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 VI - SPILL OR LEAK PROCEDURES
Procedures to Contain and Clean Up Leaks or Spills:
In the event of a battery rupture, prevent skin contact and collect all released material in a plastic lined metal
container.
Reporting Procedure:
Report all spills in accordance with Federal, State and Local reporting requirements.
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
Storage:
Store in a cool, dry, and well-ventilated area. Elevated temperature can result in shortened battery life.
Storing unpackaged cells together could result in cell shorting and heat build-up.
Mechanical Containment:
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 that 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.
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. That is much
more like to happen if the electrode is removed from its metal container. There 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.
