As a courtesy to our customers, Energizer has prepared copyrighted Product Safety Datasheets to provide information on the different
Eveready/Energizer battery systems. As defined in OSHA Hazard Communication Standard, Section 1910.1200 (c), Eveready/Energizer batteries are
manufactured 鈥渁rticles鈥?, which do not result in exposure to a hazardous chemical under normal conditions of use. For this reason, Material Safety
Datasheets are not required. The information and recommendations set forth herein are made in good faith, for information only, and are believed to be
accurate as of the date of preparation. However, ENERGIZER BATTERY MANUFACTURING, INC., MAKES NO WARRANTY, EITHER EXPRESS OR IMPLIED,
WITH RESPECT TO THIS INFORMATION AND DISCLAIMS ALL LIABILITY FROM REFERENCE ON IT.

SECTION III - FIRE AND EXPLOSION HAZARD DATA
If fire or explosion occurs when batteries are on charge, shut off power to charger.
In case of fire where nickel metal hydride batteries are present, apply a smothering agent such as METL-X, sand, dry ground dolomite, or soda ash,
or flood the area with water. A smothering agent will extinguish burning nickel metal hydride batteries. Water may not extinguish burning batteries
but will cool the adjacent batteries and control the spread of fire. Burning batteries will burn themselves out. Virtually all fires involving nickel metal
hydride batteries can be controlled with water. When water is used, however, hydrogen gas may evolve. In a confined space, hydrogen gas can form
an explosive mixture. In this situation, smothering agents are recommended.
Fire fighters should wear self-contained breathing apparatus. Burning nickel metal hydride batteries can produce toxic fumes including oxides of
nickel, cobalt, aluminum, manganese, lanthanum, cerium, neodymium, and praseodymium.
SECTION IV - HEALTH HAZARD DATA
Under normal conditions of use, the battery is hermetically sealed.
Ingestion: Swallowing a battery can be harmful.
Contents of an open battery can cause serious chemical burns of mouth, esophagus, and gastrointestinal tract.
If battery or open battery is ingested, do not induce vomiting or give food or drink. Seek medical attention immediately. CALL NATIONAL
BATTERY INGESTION HOTLINE for advice and follow-up (202-625-3333) collect, day or night.
Inhalation: Contents of an open battery can cause respiratory irritation. Hypersensitivity to nickel can cause allergic pulmonary asthma. Provide fresh
air and seek medical attention.
Skin Contact: Contents of an open battery can cause skin irritation and/or chemical burns. Nickel, nickel compounds, cobalt, and cobalt compounds
can cause skin sensitization and an allergic contact dermatitis. Remove contaminated clothing and wash skin with soap and water. If a chemical
burn occurs or if irritation persists, seek medical attention.
Eye Contact: Contents of an open battery can cause severe irritation and chemical burns. Immediately flush eyes thoroughly with water for at least
15 minutes, lifting upper and lower lids, until no evidence of the chemical remains. Seek medical attention.
Note: Nickel, nickel compounds, cobalt, and cobalt compounds are listed as possible carcinogens by International Agency for Research on Cancer
(IARC) or National Toxicology Program (NTP).

SECTION V - PRECAUTIONS FOR SAFE HANDLING AND USE
Storage: Store in a cool, well ventilated area. Elevated temperatures can result in shortened battery life.
Mechanical Containment: Never seal or encapsulate nickel metal hydride batteries.
Do not obstruct safety release vents on batteries. Encapsulation (potting) of batteries will not allow cell venting and can cause high pressure
rupture.
Handling: Accidental short circuit for a few seconds will not seriously affect the battery. However, this battery is capable of delivering very high short
circuit currents. Prolonged short circuits will cause high cell temperatures which can cause skin burns. Sources of short circuits include jumbled
batteries in bulk containers, metal jewelry, and metal covered tables or metal belts used for assembly of batteries into devices.
If soldering or welding to the battery is required, use of tabbed batteries is recommended. If this cannot be done, consult your Energizer Battery
Manufacturing, Inc. representative for proper precautions to prevent seal damage or short circuit.
Do not open battery. The negative electrode material may be pyrophoric. Should an individual cell from a battery become disassembled,
spontaneous combustion of the negative electrode is possible. This is much more likely to happen if the electrode is removed from its metal
container. here can be a delay between exposure to air and spontaneous combustion.
Charging: This battery is made to be charged many times. Because it gradually loses its charge over a few months, it is good practice to charge
battery before use. Use recommended charger. Improper charging can cause heat damage or even high pressure rupture. Observe proper
charging polarity.
Labeling: If the Eveready label or package warnings are not visible, it is important to provide a package and/or device label stating:
WARNING: CHARGE ONLY WITH SPECIFIED CHARGERS ACCORDING TO DEVICE MANUFACTURER'S INSTRUCTIONS. DO NOT OPEN
BATTERY, DISPOSE OF IN FIRE OR SHORT CIRCUIT - MAY IGNITE, EXPLODE, LEAK OR GET HOT CAUSING PERSONAL INJURY.
Where accidental ingestion of small batteries is possible, the label should state:
WARNING: (1) KEEP AWAY FROM SMALL CHILDREN. IF SWALLOWED, PROMPTLY SEE DOCTOR: HAVE DOCTOR PHONE (202) 625-
3333 COLLECT. (2) CHARGE ONLY WITH SPECIFIED CHARGERS ACCORDING TO DEVICE MANUFACTURER'S INSTRUCTIONS. DO NOT
OPEN BATTERY, DISPOSE OF IN FIRE OR SHORT CIRCUIT - MAY IGNITE, EXPLODE, LEAK OR GET HOT CAUSING PERSONAL INJURY.
Disposal: Dispose in accordance with all applicable federal, state, and local regulations.
SECTION VI - SPECIAL PROTECTION INFORMATION
Ventilation Requirements: Not necessary under normal conditions.
Respiratory Protection: Not necessary under normal conditions.
Eye Protection: Not necessary under normal conditions. Wear safety glasses with side shields if handling an open or leaking battery.
Gloves: Not necessary under normal conditions. Use neoprene or natural rubber gloves if handling an open or leaking battery.
Open Battery Storage: Battery should not be opened. Should a cell become disassembled, the electrode should be stored in a fireproof cabinet,
away from combustibles.
SECTION VII - REGULATORY INFORMATION
Batteries marketed by Energizer Battery Manufacturing, Inc. have been classified as non-dangerous goods by the US Department of Transportation and
the major international regulatory bodies and are therefore not regulated.
SARA/TITLE III - As an article, this battery and its contents are not subject to the requirements of the Emergency Planning and Community Right-To-
Know Act.
