DANGER
Personal computers manufactured by Lenovo contain a coin cell battery to
provide power to the system clock. In addition, many mobile products, such as
notebook computers, utilize a rechargeable battery pack to provide system power
when in portable mode. Batteries supplied by Lenovo for use with your product
have been tested for compatibility and should only be replaced with approved
parts.
Never attempt to open or service any battery. Do not crush, puncture, or
incinerate batteries or short circuit the metal contacts. Do not expose the battery
to water or other liquids. Only recharge the battery pack strictly according to
instructions included in the product documentation.
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 can also pose a safety hazard. Do
not let rechargeable Lithium-Ion batteries completely discharge or store these
batteries in a discharged state.
