DANGER
If the rechargeable battery is incorrectly replaced, there is danger of an explosion. The battery
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 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.

The battery is a consumable supply. If your battery begins to discharge too quickly, replace the battery
with a new one of the type recommended by Lenovo. For more information about replacing the battery,
contact your Customer Support Center.
DANGER
Do not drop, crush, puncture the battery, or make it 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 or coin-cell battery. 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 strictly according to instructions included in the product documentation.
DANGER
Do not put the battery 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 coin-cell 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.
