Guidelines for safe battery usage
This notebook uses a Lithium-ion battery. Do not use it in a humid, wet or
corrosive environment. Do not put, store or leave your product in or near a
heat source, in a high temperature location, in strong direct sunlight, in a
microwave oven or in a pressurized container, and do not expose it to
temperatures over 60° C (140° F). Failure to follow these guidelines may
cause the battery to leak acid, become hot, explode or ignite and cause
injury and/or damage. Do not pierce, open or disassemble the battery. If
the battery leaks and you come into contact with the leaked fluids, rinse
thoroughly with water and seek medical attention immediately. For safety
reasons, and to prolong the lifetime of the battery, charging will not occur at
temperatures below 0° C (32° F) or above 40° C (104° F).
The full performance of a new battery is achieved only after two or three
complete charge and discharge cycles. The battery can be charged and
discharged hundreds of times, but it will eventually wear out. When the
operation time becomes noticeably shorter than normal, buy a new battery.
Use only the approved batteries, and recharge your battery only with the
approved chargers designated for this device.
Use the battery only for its intended purpose. Never use any charger or
battery that is damaged. Do not short-circuit the battery. Accidental short-
circuiting can occur when a metallic object such as a coin, clip or pen
causes direct connection of the positive (+) and negative (-) terminals of the
battery. (These look like metal strips on the battery.) This might happen, for
example, when you carry a spare battery in your pocket or purse. Short-
circuiting the terminals may damage the battery or the connecting object.
The capacity and lifetime of the battery will be reduced if the battery is left
in hot or cold places, such as in a closed car in summer or winter. Always
