Incorrect handling of lithium batteries can result in injury
• In the event of a short circuit, overheating or mechanical damage, lithium batteries
can cause severe injuries.
• When handled correctly and appropriately lithium batteries pose no risk.
• Store lithium batteries in a cool, dry place, ideally in the original packaging.
• Store lithium batteries away from heat sources (e.g. radiators or sunlight). Lithium
batteries are hermetically sealed. Never attempt to open a lithium battery.
• If the battery housing is damaged small amounts of the electrolyte may leak out.
If this should happen, seal the lithium battery in airtight packaging and wipe up
the traces of electrolyte using absorbent paper towels. You must wear protective
rubber gloves when doing so. Clean your hands and the aected surface thoroug-
hly with cold water.
• Never attempt to recharge non-rechargeable lithium batteries. When charging lit-
hium batteries you must use a suitable charging device intended for the purpose.
• Before disposing of the device remove the lithium batteries. Protect used lithium
batteries against potential short circuits, e.g. by covering the poles with adhesive
tape.
• Only use powder extinguishers or other suitable extinguishing agents to extingu-
ish a burning lithium battery.
