Handling the battery
DANGER
Do not attempt to disassemble or modify the battery pack.
Attempting to do so can cause an explosion, or liquid leakage from the battery pack.
A battery pack other than the one specified by Lenovo, or a disassembled or modified battery
pack is not covered by the warranty.
DANGER
If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion. The battery
pack contains a small amount of harmful substances. To avoid possible injury:
Replace only with a battery of the type recommended by Lenovo.
Keep the battery pack away from fire.
Do not expose it to excessive heat.
Do not expose it to water or rain.
Do not short-circuit it.
Store it in a cool dry place.
Keep it away from children.
The battery pack is a consumable supply.
If your battery begins to discharge too quickly, replace the battery pack with a new one of the type
recommended by Lenovo. For more information on replacing the battery pack, contact your Customer
Support Center.
DANGER
Do not drop, crush, puncture, or subject to strong forces. Battery abuse or mishandling can cause
the battery to overheat, which can cause gasses or flame to “vent” from the battery pack or coin
cell. If your battery is damaged, or if you notice any discharge from your battery or the buildup
of foreign materials on the battery leads, stop using the battery and obtain a replacement from
the battery manufacturer.
