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 about 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.
DANGER
Only recharge the battery pack strictly according to instructions included in the product
documentation.
DANGER
Do not put the battery pack in trash that is disposed of in landfills. When disposing of the battery,
comply with local ordinances or regulations and your company's safety standards.
DANGER
There is a danger of an explosion if the backup battery is incorrectly placed. The lithium battery
contains lithium and can explode if it is not properly handled, or disposed of. Replace only with a
battery of the same type. To avoid possible injury or death, do not: (1) throw or immerse into water,
(2) allow it to heat to more than 100°C (212°F), or (3) attempt to repair or disassemble it. Dispose of
it as required by local ordinances or regulations and your company's safety standards.
