Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and
provides no warranties for failures or damage arising out of their use.
If an unauthorized battery is installed, the following message is displayed: "The battery installed is not
supported by this system and will not charge. Please replace the battery with the correct Lenovo battery for
this system."
DANGER
Do not attempt to disassemble or modify the battery.
Attempting to do so can cause an explosion, or liquid leakage from the battery.
A battery other than the one specified by Lenovo, or a disassembled or modified battery is not
covered by the warranty.
DANGER
If the rechargeable battery is incorrectly replaced, there is danger of an explosion. The battery
contains a small amount of harmful substance. 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.
• Keep it away from children.
The battery is a consumable supply. If your battery begins to discharge too quickly, replace the battery with a
new one of the types 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.
