blow, been dropped, run over or damaged in any way (e.g., pierced 

with a nail, hit with a hammer, stepped on). Damaged battery packs 

should be returned to the service center for recycling.

WARNING: Fire hazard. Do not store or carry the battery pack 

so that metal objects can contact exposed battery terminals.

For example, do not place the battery pack in aprons, pockets, tool 

boxes, product kit boxes, drawers, etc., with loose nails, screws, 

keys, etc. 

Transporting batteries can possibly cause fires if the 

battery terminals inadvertently come in contact with conductive 

materials such as keys, coins, hand tools and the like.

 The US 

Department of Transportation Hazardous Material Regulations (HMR) 

actually prohibit transporting batteries in commerce or on airplanes 

(e.g., packed in suitcases and carry-on luggage) UNLESS they are 

properly protected from short circuits. So when transporting individual 

battery packs, make sure that the battery terminals are protected and 

well insulated from materials that could contact them and cause a 

short circuit.

SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION (Li-Ion)

• 

Do not incinerate the battery pack even if it is severely 

damaged or is completely worn out.

 The battery pack can 

explode in a fire. Toxic fumes and materials are created when 

lithium ion battery packs are burned.

• 

If battery contents come into contact with the skin, 

immediately wash area with mild soap and water.

 If battery 

liquid gets into the eye, rinse water over the open eye for 15 

minutes or until irritation ceases. If medical attention is needed, 

the battery electrolyte is composed of a mixture of liquid organic 

carbonates and lithium salts.

• 

Contents of opened battery cells may cause respiratory 

irritation.

 Provide fresh air. If symptoms persist, seek 

medical attention.

WARNING: 

Burn hazard. Battery liquid may be flammable if 

exposed to spark or flame.
