Nickel Metal Hydride Battery

Effective Date: Jan 1 2010

SECTION IV - HEALTH HAZARD DATA

Under normal conditions of use, the battery is hermetically sealed.

Ingestion:

Swallowing a battery may be harmful.

The contents of a battery can cause serious chemical burns of mouth, esophagus, and gastrointestinal tract.

If battery or contents of the battery are ingested, do not induce vomiting or give food or drink. Seek medical attention

immediately and call the NATIONAL BATTERY INGESTION HOTLINE (202-625-3333) for treatment information.

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 which will not allow cell venting

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. Soldering directly to the

cell can damage the battery safety seal, cause internal damage or short circuit the cell.

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.
