Batteries
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.
