Using The External Battery Kit - Lenovo ThinkCentre M600 User Manual

Safety information
DANGER
There is a danger of explosion if the rechargeable battery pack is incorrectly replaced. 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.
• Keep it away from children.
Note: (JEITA guidance): Batteries are expendable products. When a fully charged battery no
longer provides sufficient run time, it should be replaced. Batteries used longer than the warranty
period may be good candidates for replacement. Battery replacements under warranty must be
validated by Lenovo using Lenovo system diagnostics installed on the computer, or available for
download at www.lenovo.com/thinkvantagetoolbox and either www.lenovo.com/powermanager_xp or
www.lenovo.com/powermanager_vista_win7. Battery life is affected by several factors such as recharge
cycle count, temperature, system usage, screen brightness, applications, and other customer preferences.
Note: Lenovo batteries are shipped partially charged to maximize shelf life. To maximize the longevity of
your battery, you should fully charge it after receiving it. Batteries should also be recharged at least twice a
year. If the battery is stored with a low charge for extended periods of time, the battery may become
unusable and might be disabled.Batteries supplied by Lenovo for use with your product have been tested
for compatibility and should only be replaced with approved parts.
A battery pack other than the one specified by Lenovo, or a disassembled or modified battery pack is
not covered by the warranty.
Lenovo does not support batteries that are not genuine Lenovo-made or authorized. Lenovo systems may
continue to boot, but may not charge unauthorized batteries.
Warning: 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.
