Material Safety Data Sheet
6. 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.
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. See medical attention.
7. 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.
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. 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.
