2.1 General Information Teledyne Isco offers two different batteries for use with its
equipment. Both batteries fit inside of or on top of Isco
equipment and fasten to the equipment with rubber draw
catches. Both have advantages and disadvantages. The choice is
ultimately up to you.
The most common battery is the Isco Model 934
Nickel-Cadmium Battery, which is described in Section 2.2.
Each cell in the nickel-cadmium battery provides 1.2 VDC and
has a capacity of 4 ampere-hours (Ah). It takes ten of these cells
connected in series to make a battery of 12 volts. The cells are
packaged in an environmentally-sealed plastic housing, supplied
with a cable and two-pin M/S connector, and provide 12 volts DC.
Also available is the Isco Model 946 Lead-Acid Battery,
described in Section 2.3. This battery is a six-cell, plastic-cased,
6.5 Ah, gelled-electrolyte type, supplied with a connector. It
delivers 12 volts. A lead-acid cell provides 2.2 volts, so six are
required for 12 volts. These batteries are popularly known as
gel-cells.
2.1.1 Battery Recycling and Batteries of all types are a significant source of toxic and envi-
Disposal ronmentally hazardous materials, primarily heavy metals. The
disposal of lead-acid, nickel-cadmium, and alkaline batteries in
landfills every year represents a growing threat to the envi-
ronment. Legislation requiring the recycling and/or proper dis-
posal of rechargeable batteries has been passed in most states.
Because the laws vary from state to state, and in each locality, it
is your responsibility to find out how to recycle or dispose of these
products properly.
Since July 1, 1993, we have labeled all equipment containing bat-
teries with the three-arrow recycling logo and the type of battery
(Ni-Cd [nickel-cadmium] or Pb [lead-acid]).
2-1
Power Products Guide
Section 2 Batteries
The product you have purchased contains a rechargeable battery.
This battery is recyclable. Disposal of this battery at the end of its
useful life in the municipal waste stream may be illegal, depending
on the laws of your state or locality. Check with solid waste officials
in your area for information on recycling options or proper disposal.
2.1.2 Battery Ratings Battery manufacturers rate the capacity of batteries in
(Ampere-Hours) ampere-hours, (availability of current over time). Typically,
manufacturers rate battery capacity at a certain current over a
specific period of time. The product of this value is the
ampere-hour rating of the battery.
Typical ratings for the discharge of nickel-cadmium batteries are
over 10 hours and for lead-acid batteries are over 20 hours. As
a result, a rating of 4 or 6.5 ampere-hours for a battery does not
mean you can draw 4 or 6.5 amperes from the battery for one
hour. The actual amount at the one-hour rate is typically
one-half the 鈥渞ated鈥? capacity of the battery, or less. To determine
the actual battery rating, you must take the nominal capacity
(4 or 6.5 ampere-hours) and divide it by 10 or 20, depending on
the battery type.
In the case of the Model 934 Nickel-Cadmium Battery, you use a
figure of 0.4, and for the Model 946 Lead-Acid Battery you will
use 0.325. Customarily, currents below 1.0 ampere are expressed
in milliamperes (mA). This means you can expect to discharge
the nickel-cadmium battery at 400 mA for 10 hours. You would
expect to discharge the lead-acid battery at 325 mA for 20 hours.
Battery manufacturers provide curves in their literature
showing the discharge rates in percentages of 鈥淐,鈥? which stands
for rated capacity in ampere-hours (Ah). If you discharge the
battery at rates greater than the 20-hour rate, you can draw
more current, but for a considerably shorter time; that is, the
value of time multiplied by current will amount to much less
than 鈥淐.鈥? For more than 20 hours, you can draw less current for a
longer time.
For times beyond 20 hours, the product of current and time will
amount to more than 鈥淐,鈥? at least, up to a point. The value of
鈥淐,鈥? or more likely a percentage of it, is also used to describe the
proper charging current for a battery.
鈥淐鈥? is useful for determining how long you can power an Isco
instrument from a particular battery. Teledyne Isco provides
average current consumption figures for most equipment. You
can use these figures as a rough estimate to calculate the
expected life of a battery connected to that equipment.

Power Products Guide
Section 2 Batteries
2.1.3 Determining Life In this example, a flow meter has an average current draw of 26
Expectancy of Charge mA. We want to power it with an Isco Nickel-Cadmium Battery.
The battery has a capacity of 4.0 Ah. First, convert 4.0 Ah into
4,000 mA-h (milliampere-hours). Then divide 4,000 mA-h by 26
mA. The result is 153.8 hours. Dividing 153.8 by 24 (hours/day),
we get 6.41, or almost 6 1/2 days. Note that you convert the
battery ampere-hour rating to milliampere-hours to make the
rating match the equipment current rating, which is in milliam-
peres. If you prefer, you could leave the battery value in
ampere-hours and convert the flow meter current rating from 26
mA to 0.026 amperes.
If you want to use the Isco Lead-Acid Battery, you would convert
the ampere-hour rating from 6.5 A-h to 6,500 mA-h, and divide
that by 26 mA to get 250 hours. Dividing 250 by 24, we get 10.4
days.
Note that the figures given for current consumption for various
Isco products are average figures based on very specific oper-
ating conditions (for flow meters), such as a bubble rate of one
bubble per second and a chart advance rate of one inch per hour.
If you set the chart advance faster, or increase the bubble rate,
the current consumption will increase.
In the same way, current consumption for a sampler depends on
how often the unit takes a sample. That will vary widely from
one sampling program to another. Note that the current figures
supplied are average currents, meaning that when the plotter
or the pump run, peak current consumption will be consid-
erably greater.
The important issue here is to be aware that current con-
sumption for your equipment will depend largely on your pro-
gramming choices. Teledyne Isco cannot guarantee a specific
current consumption for a product, because programming flexi-
bility has so great an effect on it. You may have to experiment for
some time to match the battery life expectancy with your pro-
gramming choices.
2.1.4 Charged and When fully charged, a nickel-cadmium battery tests 1.2 to 1.3
Discharged Cell volts per cell. A lead-acid battery shows 2.2 to 2.3 volts per cell.
Voltages A nickel-cadmium cell is considered fully discharged below
1.0 volt. A lead-acid battery is considered fully discharged at
1.75 volts per cell. Both values are at normal (room) tempera-
tures. You can see from these figures that a 鈥渄ead鈥? battery will
not really be dead, with both batteries showing at least 10 volts
left in them. Why not discharge this capacity to zero?
The answer lies in the fact that batteries are chemical in nature.
Chemical reactions inside the cells provide the source of elec-
tricity. Discharging a battery to zero volts risks having either of
two serious things occur. One is damage to the cell鈥檚 plates from
depletion of the active elements; the other is cell reversal.
Because no two cells in a battery are identical, discharge occurs
at different rates inside each cell. One cell usually reaches
depletion before the others. If you continue to try to draw power
from the battery, the cells with remaining capacity will force
2-3
Power Products Guide
Section 2 Batteries
current through the cell, in effect, charging it backwards. This
amounts to the electrical reversal of the two poles of the cell, and
can ruin either type of battery.
In nickel-cadmium batteries, cell reversal causes gas generation,
and that may force the vents to open. In lead-acid batteries, the
reversed cell presents a high resistance to the rest of the circuit,
making recharging difficult. Finally, while the battery may show
nearly full terminal voltage, there is, in fact, very little current
capacity left in it.
2.1.5 Self-Discharge of Self-discharge is the characteristic of all batteries that makes
Batteries them run down completely over time, even though there is no
load attached. Self-discharge is the result of inevitable chemical
reactions occurring inside the cell. This characteristic is more
serious in some types of batteries than others.
Nickel-cadmium and the newer nickel-hydride batteries have
poor charge retention. Loss of as much as 1% per day of
remaining charge has been reported. On the positive side, com-
plete self-discharge of nickel-cadmium batteries does not perma-
nently harm them. Alkaline (primary) cells, (not rechargeable)
have very good charge retention, keeping most of their charge
for several years at moderate (room) temperatures. Lithium bat-
teries, also nonrechargeable and often used for memory backup,
have excellent charge retention, as long as ten years.
Lead-acid batteries have good charge retention, retaining
about 50% of capacity after one year when stored at room tem-
perature. However, you should never allow a lead-acid battery to
self-discharge completely. Unlike the nickel-cadmium battery,
complete self-discharge will generally ruin a lead-acid battery.
Because chemical reactions cause self-discharge, temperature
has an effect. Avoid storing batteries in hot environments. The
rate of chemical reaction doubles for every 10掳 C increase in
temperature. Finally, note that the rate of self-discharge tends to
increase as the batteries age, especially for nickel-cadmium
types, while their ampere-hour capacity usually diminishes.
2.2 Model 934 The Isco Model 934 Nickel-Cadmium Battery is the most
popular battery for Isco equipment. This battery offers advan-
Nickel-Cadmium
tages over other types of batteries, particularly lead-acid types.
Battery
The number of charge/discharge cycles is quite high, as many as
500 or more, according to one manufacturer. A nickel-cadmium
battery can stay discharged indefinitely, even at very low temper-
atures, without sustaining damage. This condition would ruin a
lead-acid battery.
2-4
Power Products Guide
Section 2 Batteries
Figure 2-1 Model 934 Nickel-Cadmium Battery
The battery has an internal fuse, rated at approximately 50
amperes, to prevent the possibility of fire or burns in the event of
a short circuit. If the internal fuse link blows, you will have to
return the battery to the factory for repair.
CAUTION
Do not test these batteries for charge by 鈥渟parking鈥? the output,
and be extremely careful putting meter probes inside the out-
put connector. Any accidents resulting in a shorted output will
damage the battery in less than three seconds.
One battery manufacturer states that the short-circuit discharge
rate from a fully-charged nickel-cadmium battery can be as much
as 50 to 100 times 鈥淐.鈥? For the Isco Model 934 Battery, this
could be from 200 to 400 amperes of discharge current. Usually,
the resistance of the wires prevents so large a current from
leaving the battery, but it is a dangerous level, in any case. Cur-
rents this large can do extensive damage, mostly from the heat
generated. That is why the battery is fused.
2.2.1 Charging You can recharge the nickel-cadmium battery with an Isco Power
Pack, an Isco Battery Charger, or with the Model 965 Five
Station Battery Charger. All these provide the proper current
(400 mA) for charging the batteries. To charge the battery,
connect the plug on the battery cable to the mating receptacle on
the power pack, or the connector on the charger. Leave the
battery on charge for 15 to 18 hours. The Five-Station Battery
Charger lets you charge as many as five batteries at once, and
lets you charge both nickel-cadmium and lead-acid batteries,
although not at the same time.
CAUTION
Never charge any battery inside a sealed container or enclo-
sure. Charging may release gases from the electrolyte. These
gases can generate dangerous pressure as they try to escape
2-5
Power Products Guide
Section 2 Batteries
confinement from the cells or enclosure. The gases may be
explosive and they can also be irritating to smell.
All rechargeable batteries, whether nickel-cadmium or
lead-acid, have one-way safety vents that open to relieve inter-
nal pressure generated by overcharging or very heavy dis-
charge. Their purpose is to keep the battery from bursting,
catching fire, or even exploding.
These vents do not open during normal operation. If they do
open, it indicates battery abuse. Venting shortens battery life
by depleting irreplaceable electrolyte. Avoid causing any of the
conditions that can make this happen.
2.2.2 Charging Temperature One manufacturer of nickel-cadmium cells recommends charging
them within a temperature range of 32掳 F (0掳 C) to 110掳 F (45掳
C). Below 32掳 F, charging increases the gas pressure within the
cell, and that may force the safety vent to open. Above 110掳 F,
charging efficiency decreases, and the high temperature accel-
erates deterioration of the plate separator material, hastening
end-of-life.
Measuring nickel-cadmium batteries shows an almost-constant
output voltage from charged to discharged. This is because the
electrolyte, water and potassium hydroxide (KOH), is not
depleted of ions (which affects conductivity) during discharge, as
is the electrolyte in lead-acid batteries. As a result, you cannot
measure the output voltage to calculate the remaining charge in
the battery. You can achieve the recommended 15-hour charging
interval by putting the battery on charge before leaving work in
the evening and then taking it off when you come in the next
morning (5 PM to 8 AM is 15 hours). As long as the battery is
accepting the charge, it will stay cool to the touch. When fully
charged, the battery will feel warm, as it dissipates the charging
current as heat. Discontinue charging when the battery feels
warm.
2.2.3 Avoiding As mentioned, nickel-cadmium batteries have a higher rate of
Self-Discharge self-discharge than other types of batteries. After charging,
always try to return the battery to service within a reasonable
period of time (one to two weeks at most), to ensure the avail-
ability of most of the battery's capacity. Self-discharge does not
affect the life or usability of nickel-cadmium batteries, and it
does not mean the batteries are bad. It just means that the bat-
teries will not deliver full-rated capacity if you do not return
them to service promptly after charging.
Do not store the batteries in a hot environment, such as a room
with a furnace, boiler, or heater, or in direct sunlight, if at all pos-
sible. The self-discharge characteristic seems to increase with
age, probably due to the deterioration of the plate separator
material and the growth of crystalline 鈥渨hiskers鈥? between the
plates.
2-6
Power Products Guide
Section 2 Batteries
We suggest you discontinue the use of 鈥渙ld鈥? batteries. Rapid
self-discharge is often the actual cause of unreliability in older
batteries, not diminished capacity. The manufacturer of the cells
used in the Isco battery considers end-of-life to have occurred
when battery capacity has dropped to 80% of the rating for new
cells.
Finally, if you cannot return the battery to service immediately
or don't know the charge condition, simply 鈥渢op off 鈥? the charge
for a few hours.
2.2.4 Effects of Overcharging Overcharging the nickel-cadmium battery causes the cells to
the Battery heat up. Over time this heating breaks down the separator
material used between the plates inside the cells, encouraging
the growth of the crystalline whiskers, causing shorts. Prolonged
overcharging will shorten the life of the cells; try to avoid it.
2.2.5 Using Other Battery Teledyne Isco does not recommend the use of chargers designed
Chargers for lead-acid batteries, such as automotive battery chargers. The
open-circuit voltage of lead-acid chargers is generally not high
enough to fully charge a nickel-cadmium battery, and these
chargers are usually not current-regulated. Neither does
Teledyne Isco recommend using chargers intended for other
types of nickel-cadmium batteries, especially the so-called
鈥渇ast-charge鈥? types. These chargers are designed for use only
with compatible 鈥渇ast-charge鈥? cells and can charge the proper
batteries in as little as one hour (1.0 鈥淐鈥?). Isco batteries use
鈥渟tandard鈥? cells intended for charging at 400 mA (0.1 鈥淐鈥?) for 15
to 18 hours. Chargers that provide more current than this may
cause overheating and that may force the safety vents to open,
releasing water. You cannot replace this water.
Chargers that deliver too little current to the batteries may
never charge them to full capacity, and may themselves be
damaged from the overload. Do not attempt to use any other
charging apparatus without an accurate digital multimeter to
monitor the charging current. If the charger delivers more than
600 mA, Teledyne Isco recommends you do not use it. If it
delivers less than 100 mA, the charging period becomes too long.
Even then the battery may never recharge completely. Be sure
of proper polarity before connecting any other charging
apparatus! If you use an Isco Power Pack, you can overcharge
the battery occasionally with little loss of capacity. However, you
should avoid chronic or prolonged overcharging. Again, return
the battery to service promptly.
2.2.6 鈥淢emory鈥? Effects For a long time, people believed that nickel-cadmium batteries
were subject to 鈥渕emory鈥? effects, and that a complete charge/dis-
charge cycle (exercising the battery) was necessary to maintain
battery capacity. 鈥淢emory鈥? is the characteristic a battery may
develop of appearing to have lost some of its capacity after a few
shallow discharges.
The battery will only discharge to the same shallow point. It is
now known that the memory effect is not a problem under
normal operating conditions, because most Isco applications gen-
2-7
Power Products Guide
Section 2 Batteries
erally involve a deep or full discharge. If it does occur, it is tem-
porary, and you can reverse it by a deep discharge and charge. If
you discharge the battery to random depths, charge for random
amounts of time, and subject the battery to various duty cycles,
the memory effects will not be present.
2.2.7 Servicing the This section covers replacement of the connect cable. You can
Nickel-Cadmium make this repair yourself. However, some familiarity with elec-
Battery trical/electronic repair procedures is necessary. You must know
how to solder, make proper splices, and insulate them safely. You
must follow the color codes used to maintain proper polarity on
the battery after the repair. If you are not familiar with these
procedures, or are uncomfortable doing them, return the battery
to Teledyne Isco for repair. If the fuse is all right and only the
cable needs replacing, Teledyne Isco suggests making the repair
after the battery has been discharged.
2.2.8 Replacement of the If the cable on the nickel-cadmium battery is damaged or inoper-
Battery Cable ative, you can replace it in the field. Remove the screws holding
the battery cover. Lift the cover from the case to reveal the cable
connections. To make replacement easier, the connections are
outside the potting wax. To replace the cable, simply cut away
the old cable and splices, one wire at a time, and solder in a
replacement. Carefully insulate the exposed wires with shrink
tubing (preferred) or electrical tape. Replace the battery case
cover and screws.
WARNING
When replacing a battery cable, be careful not to short the
leads from the battery together, or you may irreparably
damage the battery and you may also risk personal injury.
Insulate splices carefully. Replace only one wire at a time.
2.3 Model 946 Lead-Acid While the nickel-cadmium battery has traditionally been the
usual battery for powering Isco products, Teledyne Isco also
Battery
offers a 6.5 ampere-hour gelled-electrolyte 12-volt lead-acid
battery (see Figure 2-2). Either battery will operate an Isco
sampler, flow meter, portable pump, or other equipment satisfac-
torily, but there are differences in the charging and operating
characteristics of the lead-acid battery.
2-8
Power Products Guide
Section 2 Batteries
Figure 2-2 Model 946 Lead-Acid Battery
The lead-acid battery offers higher capacity than the
nickel-cadmium battery at a lower price. However, fewer
charge-discharge cycles are generally possible. If your experience
has been with the nickel-cadmium battery, please study the fol-
lowing before using the lead-acid battery.
鈥? Do not run an instrument to complete discharge
of the battery. Total discharge of gelled-electrolyte
batteries can cause cell reversal, and this can ruin the
battery. One manufacturer recommends 10.5 VDC,
loaded at 400 mA, as complete discharge of a 12-volt
battery.
鈥? Although it may appear that there is still much
power left when the battery voltage drops to 10.5
VDC, in fact, there is very little. Trying to use all
remaining power from a battery will cause cell reversal.
The weakest cell is the first to fail in a battery. The first
cell depleted will be forced into reversal by the rest of
the battery, if the load is still connected.
鈥? Recharge lead-acid batteries as soon as possible
after use. Unlike nickel-cadmium batteries, if you leave
lead-acid batteries partially or fully discharged for any
period of time, they may not recharge to full capacity.
Eventually they will not accept or retain a charge at all.
鈥? Battery life is related to the depth of the
discharge cycle. One manufacturer specifies that you
can expect only 200 cycles at 100% discharge for each
cycle. With a 50% depth of discharge, this number
increases to over 400 cycles. With a 30% depth of
discharge, cycle expectancy increases to over 1,000.
鈥? Avoid the use of lead-acid batteries in subfreezing
environments, especially where you expect deep
discharge. One manufacturer recommends that you
use them above 5o F (鈥?15o C). While a fully-charged
lead-acid battery will withstand cold temperatures, a
discharged battery can freeze if the temperature is low
enough, and that can ruin it. If frozen, the battery could
2-9
Power Products Guide
Section 2 Batteries
swell and crack the case. This will ruin the battery and
could also release toxic substances.
鈥? You can easily damage a gelled-electrolyte
lead-acid battery by overcharging. By necessity, the
amount of water in a gelled-electrolyte battery is quite
limited. The batteries have a one-way safety vent in
each cell that releases water when overcharging causes
the pressure to build up inside the battery. Unlike
wet-cell lead-acid batteries (such as automotive types),
you cannot replace the water. Repeated venting will dry
out the cells and kill the battery. Optimal charging
causes the battery to release no water vapor and very
little gas from the plates.
鈥? Lead-acid batteries are not charged the same way
as a nickel-cadmium battery. Proper charging is done
with a constant voltage and a tapering (or declining)
current.
Chargers for nickel-cadmium batteries typically use a con-
stant-current method. Overcharging is more likely to damage a
lead-acid battery by forcing the vents open and drying it out.
2.3.1 Charging Lead-Acid Isco鈥檚 Model 963 Single Station Battery Charger can be used
Batteries to charge lead-acid batteries.
In addition, the Isco Model 965 Five-Station Battery
Charger has outputs that can be switched for lead-acid bat-
teries.
Some battery manufacturers recommend charging the lead-acid
battery near room temperature (70掳 F or 23掳 C), if possible.
Chargers are typically designed to operate at room temperature.
Temperatures deviating significantly either direction from room
temperature may cause inaccuracies in charging the lead-acid
battery, with potentially harmful long-term effects. The Model
965 Five-Station Battery Charger contains compensation for
charging at higher and lower temperatures, but the other
chargers do not.
When charging lead-acid batteries of any type, please consider
the following:
鈥? Disconnect the battery from the equipment it is
powering before charging.
鈥? Connect the battery to the charger before plugging the
charger in or turning it on; this prevents sparks.
鈥? Never charge the battery in a sealed container, nor in an
unventilated room.
鈥? Do not let the charger run unsupervised or for a long
period of time.
鈥? Do not charge the battery upside down.
鈥? Charging produces explosive gases; do not charge near open
flames or sparks.
鈥? Do not smoke around the battery while it is charging.
2-10
Power Products Guide
Section 2 Batteries
鈥? Do not overcharge the battery.
鈥? Unplug the charger from the AC supply before discon-
necting the battery. This will prevent any sparking that
could ignite the gases produced by charging.
Charge retention is substantially better for lead-acid batteries
than for nickel-cadmium types. While a nickel-cadmium battery
can self-discharge completely in a matter of months, a lead-acid
battery will still have 50% of capacity for nine months to a year
when stored at room temperature (70掳 F or 23掳 C). At 100掳 F (38掳
C), the time drops to four months. At 40掳 F (5掳 C), the time is over
a year.
However, if a lead-acid battery does self-discharge completely, it
will often be ruined, due to sulfation of the plates. This is very
different from the nickel-cadmium battery, which is not harmed
by remaining in the discharged state, even for considerable
periods of time.
The voltage available from a lead-acid battery drops in a straight
line as the battery discharges. This is due to depletion of sulfate
ion from the electrolyte, raising the internal resistance. Available
voltage drops gradually from approximately 12.5 at full charge to
10.5 at total discharge (under load). Note that it is important to
measure the battery under load. A discharged lead-acid battery
may still show 12.5 VDC, when measured with no load.
Nickel-cadmium batteries show essentially constant voltage
across most of the discharge range.
2-11
Power Products Guide
Section 2 Batteries
2.3.2 Using Other Battery Note that an earlier version of the five-station charger is for use
Chargers with nickel-cadmium batteries only. You can use chargers for
Isco nickel-cadmium batteries to charge lead-acid bat-
teries, but it is NOT recommended!
Yo u m u s t b e c a r e f u l t o a v o i d o v e r c h a r g i n g , s i n c e a
nickel-cadmium charger delivers too much current in the latter
stages of charging. Since its open-circuit voltage is high (30
VDC), the current will remain constantly high, no matter what
the charge state of the battery is. If not turned off at the proper
time, the charger will boil the electrolyte. There is a table printed
on the lead-acid battery that tells you how long to charge with a
nickel-cadmium charger.
Because of the risk of damage to the battery from a
nickel-cadmium charger, consider using an accurate digital volt-
meter to monitor the charge voltage. Discontinue charging when
the battery voltage reaches 15.0 VDC. Charging until the
battery 鈥渇eels warm鈥? is not a reliable indicator for these batteries,
as you may already have overcharged them. Discontinue
charging if you hear a bubbling sound coming from the batteries.
2.4 Model 948 Lead-Acid In addition to the Model 946 and 947 Lead-Acid Batteries,
Teledyne Isco offers a much larger battery, the Model 948. This
Battery
battery, which resembles an automotive battery, has a capacity of
45 ampere-hours, seven times the capacity of Models 946 and
947.
Like the Model 946 battery, the Model 948 is a gelled-electrolyte,
maintenance-free battery. This battery is particularly well-suited
to installations that have moderate-to-heavy power require-
ments. It is also suitable for installations that have fairly low
power requirements, but because of their location, must operate
unsupervised for long periods of time.
Figure 2-3 Model 948 Battery
2-12
Power Products Guide
Section 2 Batteries
Teledyne Isco offers the battery, a convenient carrying case (rec-
ommended) and a six-foot connect cable. The cable terminates
in a two-pin M/S connector suitable for attachment to Isco sam-
plers and flow meters. The cable is protected with grease where
it connects to the battery.
Teledyne Isco also offers a special battery charger suitable for
recharging the Model 948 Battery (Figure 2-4). We recommend
the use of this charger, as it automatically senses when the
battery is charged and reduces the current to a safe level, thus
avoiding the possibility of overcharge. Most automotive-type
chargers do not have this capability.
This charger has an output of 6 amperes and is supplied with
leads terminated in alligator clips for easy connection to the
battery. To recharge the Model 948, simply remove the top of the
carrying case and connect the red (positive +) clip to the positive
(+) terminal on the battery and the black (negative 鈥?) clip to the
negative (鈥?) terminal on the battery. Follow the instructions
printed on the charger. For safe charging refer to the comments
made for the Model 946.
If you want to charge the battery with a different charger, note
the charging conditions indicated on the battery label. The
battery manufacturer recommends that the initial charge not
exceed C/5, which in this instance would be 9 amperes.
Chargers for smaller Isco batteries are not recommended for the
Model 948, as they will take too long to recharge the battery. Note
the nylon webbed strap around the battery case. Its purpose is to
keep the case closed, not a carrying handle. Carry the battery
case by the handles molded into both narrow ends of the case.

Section 2 Batteries
2.5 Use of Other Types of In some circumstances, you may want to use batteries other than
the nickel-cadmium and gelled lead-acid types. For long-term
Batteries
operation, the deep-cycle R-V or marine battery has been a
popular and satisfactory choice, due to its high ampere-hour
capacity and reasonable cost. In certain instances you can also
use alkaline (non-rechargeable) batteries with Isco equipment.
However, you should consider the environmental impact of
alkaline batteries because of the one-time-only use and necessity
of disposal of the spent batteries.
2.5.1 Alkaline Generally, you should only consider alkaline batteries where
(Nonrechargeable) power consumption by the equipment is extremely low and long
Batteries periods of unsupervised operation are required. The samplers
cannot use alkaline batteries, due to power requirements, and
their use with flow meters is not recommended. One application
where alkaline batteries are suitable is the 4100 series flow
loggers. The flow loggers use two, 6-volt 鈥渓antern鈥? batteries.
2.5.2 Deep-Cycle R-V or Similar in appearance and construction to an automotive battery,
Marine Batteries but specially designed to withstand deep discharges, the
deep-cycle R-V or marine battery works with Isco samplers, flow
meters, pumps, and other equipment. These batteries are quite
large compared to the standard Isco battery packs, so you must
mount them separately from the equipment they are powering.
CAUTION
Mount wet cell batteries securely so they cannot tip over. This
is important because the acid in the electrolyte is both corro-
sive and toxic.
Connection between battery and equipment is with a special Isco
cable. This cable has a two-pin M/S connector on one end and two
large alligator clips on the other.
The positive clip (+) has red shrink tubing on its wire to correctly
identify polarity. Verify polarity with a meter. Attach the clips to
the proper terminals on the battery and plug the M/S connector
into the instrument.
2.5.3 Maintenance and Keep the terminals on the battery posts clean at all times.
Charging Lead-acid batteries are notorious for 鈥済rowing鈥? corrosion on the
battery posts. These deposits will rapidly cause the conductors to
fail if allowed to form for any length of time. You can easily
identify the corrosion as white flakes or powdery deposits. Cor-
rosion on the terminals also can creep into the attached alligator
clips, especially the positive one. These deposits are harmful
because they will eventually corrode the metal (conductive) ele-
ments of the circuit completely away and because they form good
insulators when dry. Grease, baking soda, and corrosion-inhib-
iting felt washers (available from auto-parts suppliers) are all
helpful in keeping the connections between the battery and the
cable reliable and corrosion-free.
2-14
Power Products Guide
Section 2 Batteries
If the battery is not the sealed type, you should check the level of
the electrolyte in each cell every time you recharge it. Unsealed
batteries have caps on top of the case that you can remove to
check the electrolyte. Add only distilled water according to the
battery manufacturer's recommendations; never add common
tap water or more electrolyte. You can check charge condition
and the condition of each cell with an ordinary battery
hydrometer, a device that measures the specific gravity of the
electrolyte. Follow the battery manufacturer鈥檚 recommendations
for charging the battery. An automotive-type charger is usually
satisfactory for charging these batteries. Isco chargers are
designed for batteries with low ampere-hour capacities; their use
in this application is not recommended.
2.5.4 Hazard of Short As advised for the nickel-cadmium battery, do not check the
Circuits charge condition of either lead-acid or gelled-electrolyte batteries
by 鈥渟parking鈥? the output cables (momentarily shorting the wires
together). These batteries, when fully charged, can deliver large
amounts of current into a short circuit fault, especially if the
short is close to the battery. While the current may not be as high
as a nickel-cadmium battery, it is still considerable. Unlike
nickel-cadmium batteries, lead-acid batteries are not internally
fused. Enough current can flow to burn up the wires quickly. It is
possible for battery cables shorted together to 鈥渨eld.鈥? This will
cause almost immediate melting and burning of the wire insu-
lation until the wire melts open at some point.
WARNING
Fire, severe burns to the hands, and the release of toxic
fumes are all possible from such a mishap.
CAUTION
If you intend to use any power source other than an Isco bat-
tery or power converter, be sure of proper voltage and polar-
ity before connecting power to the equipment.
Never attach equipment to a power source of unknown polarity
or voltage. Never attach equipment directly to an AC power
source under any circumstances, regardless of voltage.
If you are in doubt, check the power with a reliable DC volt-
meter. Failure to observe this caution could create a shock or fire
hazard, cause serious damage to the instrument, and it could
also put you at risk of serious personal injury.

Section 3 Batteries for Flow Loggers
3.1 Internally Mounted The flow loggers contain internal mounting provisions for two
different types of batteries. The first type is a pair of standard
Batteries
6-volt alkaline 鈥渓antern鈥? batteries. The second is a 6.5 Ah, 12-volt
lead-acid battery, similar to the standard Isco Lead-Acid Battery,
but with a different cable and connector. You can also use the
Solar Panel Battery Charger, modified to accept a standard Isco
Lead-Acid Battery and supplied with an interconnect cable.
3.2 Model 947 Lead-Acid Electrically identical to the Model 946 Isco Lead-Acid Battery,
this battery comes with its own special cable and connector. You
Battery
must use this special arrangement with the flow loggers if you
want the battery to be self-contained, as the standard Lead-Acid
Battery will not fit inside the flow logger case. You can recharge
this battery the same as you recharge the standard Isco
Lead-Acid Battery.

Put the batteries into the flow logger case with the contact
springs pointing towards the bottom of the battery compartment.
Positioning is not critical, because the contact strips in the
bottom of the compartment are laid out for universal acceptance.
These batteries are available from Teledyne Isco or from any
local hardware, sporting goods, or electronics wholesaler.
Note that this type of battery is not rechargeable, despite occa-
sional claims to the contrary. Attempting to recharge alkaline
batteries is reputed to be hazardous in some instances. Never
dispose of alkaline batteries in a fire. Always dispose of dis-
charged alkaline batteries in conformance with state and local
environmental regulations.
3.4 Flow Loggers - If you want to use an external power source with the flow loggers,
almost any of the Isco batteries and power supplies are suitable.
External Power
The flow loggers have an external power connector on the case
Sources
and there is a two-foot cable available to connect to an external
power source.
Note that if you suspend a flow logger from the rungs of a man-
hole, use of an external power source is not practical, as you must
secure both the flow logger and the battery. It is generally not
possible to use an AC-powered unit in a manhole due to the lack
of availability of an AC power connection. The following devices
are suitable as external power sources for the flow loggers:
Batteries
鈥? Isco Model 946 Lead-Acid Battery
鈥? Isco Model 948 Lead-Acid Battery
鈥? 12-Volt R-V Deep-Cycle or Marine Battery
Note
You can use the Isco Model 934 Nickel-Cadmium Battery with
the flow loggers, but Teledyne Isco does not recommend it.
This battery is not ideal for use with the flow loggers because
of its self-discharge characteristic. Because the flow loggers
need to operate over the long-term, the nickel-cadmium bat-
tery is more likely to run down from self-discharge than it is to
run down from the flow logger power demands on it.

Section 4 Isco Battery Chargers and Power Packs
4.1 Isco Chargers and Teledyne Isco offers several battery chargers and two different
power packs for use with all Isco products. You can use the power
Power Packs
packs instead of the nickel-cadmium or lead-acid batteries to
power the samplers, flow meters, or other equipment.
The power packs are made for operation from either nominal 120
VAC, 60 Hz (USA) or 220-240 VAC, 50 Hz (Europe and much of
the rest of the world) power sources. The 120-volt models are
supplied with the three-prong cord commonly used in the USA
and Canada. The 220-240-volt models are supplied with the most
common two-prong plug used in Europe.
4.2 Model 961 Battery The simplest charger is a wall plug-in transformer type, Model
961, intended for charging the Model 934 Nickel-Cadmium
Charger

at 50/60 Hz. The Model 963 Battery Charger is listed by UL
(Underwriters Laboratories) and is CE marked.
The Model 963 is a float type charger that will vary its output as
the batteries become more charged, thus reducing the risk of
overcharging.
A fully discharged 946 or 947 battery should be fully charged
within 15 to 18 hours. These batteries will not be damaged by
occasional or slight overcharging, but frequent or prolonged over-
charging will result in reduced charge capacity and fewer
charge/discharge cycles in the life of the battery.

certain the selector switch is appropriate for the battery you are
charging before applying power.
Generally the batteries (either type) will attain full charge
within 15 to 18 hours. Occasional or slight overcharging of the
batteries will not hurt them, but Teledyne Isco recommends that
you avoid frequent or prolonged overcharging. Each Five-Station

Section IV - Fire and Explosion Hazard Data
Flash point: NA Lower Explosive Limit: NA Upper Explosive Limit: NA
Extinguishing Media: Any class of extinguishing medium may be used on the batteries or their packing material.
Special Fire Fighting Procedures: Exposure to temperatures of above 212掳F can cause evaporation of the liquid content of
the potassium hydroxide electrolyte resulting in the rupture of the cell. Potential for exposure to cadmium fumes during fire;
use self-contained breathing apparatus.
Section V - Health Hazard Data
Threshold Limit Values: See Section II
Effects of a Single (Acute) Overexposure:
Inhalation:
During normal use inhalation is an unlikely route of exposure due to containment of hazardous materials within the
battery case. However, should the batteries be exposed to extreme heat or pressures causing a breach in the
battery cell case, cadmium dusts and fumes may be emitted. Inhalation of cadmium dusts or fumes may cause
throat dryness, respiratory irritation, headache, nausea, vomiting, chest pain, extreme restlessness and irritability,
pneumonitis, and bronchopneumonia. In the case of high concentration exposures (e.g., above 1 to 5 mg/m3 during
an eight hour period) death may occur within several days after the exposure.
Ingestion:
If the battery case is breached in the digestive tract, the electrolyte may cause localized burns. Ingestion of
cadmium compounds may result in increased salivation, choking, nausea, persistent vomiting, diarrhea, abdominal
pain, anemia, tenesmus, and kidney dysfunction.
Skin Absorption:
No evidence of adverse effects from available data.
Skin Contact:
Exposure to the electrolyte contained inside the battery may result in chemical burns. Exposure to nickel may cause
dermatitis in some sensitive individuals.
Eye Contact:
Exposure to the electrolyte contained inside the battery may result in severe irritation and chemical burns.
Carcinogenicity:
Cadmium and nickel have been identified by the National Toxicology Program (NTP) as reasonably anticipated to be
carcinogens. U.S. EPA classified cadmium as a "B1" probable human carcinogen. The International Agency for
Research on Cancer (IARC) recommended that cadmium be listed as a "2A" probable human carcinogen, and the
American Conference of Governmental Industrial Hygienists (ACGIH) has proposed listing cadmium as an A2
carcinogen.
The information and recommendations set forth are made in good faith and believed to be accurate as of the date of
preparation. SANYO ENERGY CORP. makes no warranty, expressed or implied, with respect to this information and
disclaims all liabilities from reliance on it.

Other Effects of Repeated (Chronic) Exposure:
Repeated overexposures to cadmium may result in lung cancer; lung, kidney, and liver dysfunction; skeletal disease
(e.g., osteoporosis) and reproductive toxicity. Chronic overexposure to nickel may result in cancer; dermal contact
may result in dermatitis in sensitive individuals.
Medical Conditions Aggravated by Overexposure:
A knowledge of the available toxicology information and of the physical and chemical properties of the material
suggests that overexposure in unlikely to aggravate existing medical conditions.
Emergency and First Aid Procedures:
Swallowing:
Do not induce vomiting. Seek medical attention immediately.
Skin:
If the internal cell materials of an opened battery cell comes into contact with the skin, immediately flush with water
for at least 15 minutes.
Inhalation:
If potential for exposure to cadmium or nickel fumes or dusts occurs, remove immediately to fresh air and seek
medical attention.
Eyes:
If the contents from an opened battery comes into contact with the eyes, immediately flush eyes with water
continuously for at least 15 minutes. Seek medical attention.
Section VI - Health Hazard Data
The batteries are stable under normal operating conditions.
Hazardous polymerization will not occur.
Hazardous decomposition products: oxides of cadmium and nickel.
Conditions to avoid: heat, open flames, sparks, and moisture.
Potential incompatibilities (i.e., materials to avoid contact with): The battery cells are encased in a non-reactive container;
however, if the container is breached, avoid contact of internal battery components with acids, aldehydes, and carbamate
compounds.
Section VII - Health Hazard Data
Spill and leaks are unlikely because cells are contained in an hermetically-sealed case. If the battery case is breached, don
protective clothing that is impervious to caustic materials and absorb or pack spill residues in inert material. Dispose of as a
hazardous waste in accordance with applicable state and federal regulations. Resultant spill residues may be characterized
as D002 (caustic) and D006 (cadmium) pursuant to the federal Resource Conservation and Recovery Act (RCRA). See
Section IV for response to fires or explosions.

Section VIII - Safe Handling and Use (Personal Protective Equipment)
Ventilation Requirements: Not required under normal use.
Respiratory Protection: Not required under normal use.
Eye Protection: Not required under normal use.
Gloves: Not required under normal use.
Section IX- Precautions for Safe Handling and Use
Storage:
Store in a cool place, but prevent condensation on cell or battery terminals. Elevated temperatures may result in
reduced battery life. Optimum storage temperatures are between -31掳F and 95掳F.
Mechanical Containment:
If there are special encapsulation or sealing requirements, consult your SANYO Energy Corp. representative about
possible cell hazard precautions or limitations.
Handling:
Accidental short circuit will bring high temperature elevation to the battery as well as shorten the battery life. Be sure
to avoid prolonged short circuit since the heat can burn attendant skin and even rupture the battery cell case.
Batteries packaged in bulk containers should not be shaken. Metal covered tables or belts used for assembly of
batteries into devices can be the source of short circuits; apply insulating material to assembly work surface.
Soldering/welding:
If soldering or welding to the case of the battery is required, consult your Sanyo Energy Corp. representative for
proper precautions to prevent seal damage or external short circuit.
Charging:
This battery is designed for recharging. A loss of voltage and capacity of batteries due to self-discharge during
prolonged storage is unavoidable. Charge battery before use. Observe the specified charge rate since higher rates
can cause a rise in internal gas pressure which may result in damaging heat generation or cell rupture and or
venting.
Section X- Recycling and Disposal
SANYO encourages battery recycling. Our Nickel Cadmium batteries are recyclable through the Rechargeable Battery
Recycling Corporation's (RBRC) Charge Up to Recycle! Program. For information call 1-800-8-BATTERY or see their
website at www.rbrc.org. Ni-Cd batteries must be handled in accordance with all applicable state and federal laws and
regulations.
The information and recommendations set forth are made in good faith and believed to be accurate as of the date of
