Material Safety Data Sheet

Section 1: Chemical product identification

Name of Product: Lithium Manganese Dioxide Battery

Product model: CR2477

Section 2: Hazards identification

This contains lithium, organic solvent, and other combustible materials. For this reason, improper handling of the battery could lead to distortion, leakage*, overheating, explosion of fire and cause human injury or equipment trouble. Please strictly observe safety instructions.

(*Leakage is defined as an unintended escape of liquid from a battery.)

Section 4: First aid measures

None unless internal materials are exposed. If contents are leaked out, read the following instructions.

InhalationFumes can cause respiratory irritation. Remove to fresh air and consult a physician.
SkinImmediately flush the skin with plenty of water. If itch or irritation by chemical bum persists, consult a physician.
EyesImmediately flush eyes with plenty of water for at least 15 minutes. Consult a physician immediately.
IngestionIf swallowing a battery, consult a physician immediately. If contents come into mouth, immediately rinse with plenty of water and consult a physician.

Section 5: Firefighting measures

Extinguishing agentAn extinguisher of alkaline metal fire is effective. Plenty of cold water is also effective to cool the surrounding area and control the spread of fire. But hydrogen gas may evolve by the reaction of water and lithium and it can form an explosive mixture. Therefore, in the case that lots of lithium batteries are burning in a confined space, use a smothering agent.
Firefighting procedureUse self-contained breathing apparatus and full protective gear not to inhale harmful gas.

Section 6: Accidental release measures

Accidental ReleasesDo not breathe vapors or touch liquid with bare hands (see section 4).
Waste Disposal MethodsEvacuate area. If possible, a trained person should attempt to stop or contain the leak by neutralizing the spill with soda lime or baking soda. A NIOSH Approved Acid Gas Filter Mask or Self-Contained Breathing Apparatus should be worn. Seal leaking battery and soda lime or baking soda in a plastic bag and dispose of it as hazardous waste.
OtherFollow North American Emergency Response Guide (NAERG)#138 for cells involved in an accident, cells that have vented, or have exploded.

Section 7: Handling and storage

1) Handling

Never swallow.

Never reverse the positive and negative terminals when mounting.

Never short-circuit the battery.

Never heat.

Never expose to open flame.

Never disassemble.

Never weld the terminal or wire to the body of the battery directly.

Never touch the liquid leaked out of the battery.

Never bring fire close to battery liquid.

Never keep in touch with the battery.

2) Storage

Never let the battery contact with water.

Never store the battery in a hot and high humid place.

Section 12: Ecological information

Aquatic Toxicity: Do not let internal components enter marine environments. Avoid releases into waterways, wastewater, or groundwater.

Section 13: Disposal considerations

The battery disposal may be regulated by national or local government regulation. Please follow the instructions of proper regulation. As electric capacity is left in a discarded battery and it comes into contact with other metals, it could lead to distortion, leakage, overheating, or explosion, so make sure to cover the (+) and (-) terminals with friction tape or some other insulator before disposal.

Section 14: Transport information

In general, all cells/batteries being transported by ship, aircraft or railway, must be packaged in a safe and responsible manner. Do not leave them in high temperature or in high condensation. Battery cartons should be handled with care. Rough handling may result in batteries being short circuited or damaged.
