General battery notice
DANGER
Batteries supplied by Lenovo for use with your product have been tested for compatibility and
should only be replaced with approved parts. A battery other than the one specified by Lenovo, or a
disassembled or modified battery is not covered by the warranty.
Battery abuse or mishandling can cause overheating, liquid leakage, or an explosion. To avoid
possible injury, follow these instructions:
• Do not open, disassemble, or service any battery.
• Do not crush or puncture the battery.
• Do not short-circuit the battery, or expose it to water or other liquids.
• Keep the battery away from children.
• Keep the battery away from fire.
Stop using the battery if it is damaged, or if you notice any discharge or the buildup of foreign
materials on the battery leads.
Store the rechargeable batteries or products containing rechargeable batteries at room
temperature, with batteries charged to approximately 30%–50% of the full capacity. We recommend
that the batteries be charged at least once per year to prevent over-discharging.
Do not put the battery in trash that is disposed of in landfills. When disposing of the battery, comply
with local ordinances or regulations.
