© Copyright Lenovo 2013 vii
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.
Batteries can degrade when they are left unused for long periods of time. For some rechargeable
batteries (particularly Lithium Ion batteries), leaving a battery unused in a discharged state could
increase the risk of a battery short circuit, which could shorten the life of the battery and also can
pose a safety hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or store
these batteries in a discharged state.
Rechargeable battery notice
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.
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 water or rain.
• Do not attempt to disassemble it.
• Do not short-circuit it.
