Guidelines for safe battery usage
This computer uses a Lithium-ion or Lithium-polymer 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 computer or 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, refer to qualified service personnel. Use only the approved batteries, and
recharge your battery only with the approved chargers designated for this device.
The capacity and lifetime of the battery will be reduced if the computer is left in hot or
cold places, such as in a closed car in summer or winter. Always try to keep the computer
between 15°C and 25°C (59°F and 77°F). A device with a hot or cold battery may not
work temporarily, even when the battery is fully charged. Battery performance is
especially limited in temperatures well below freezing.
Do not dispose of batteries in a fire as they may explode. Batteries may also explode if
damaged. Dispose of batteries according to local regulations. Please recycle when
possible. Do not dispose as household waste.
Wireless devices may be susceptible to interference from the battery, which could affect
performance.
­ Note: Please refer to www.acer.com for battery shipping documents.
Warning! Batteries may explode if not handled properly. Do not disassemble or dis-
pose of them in fire. Keep them away from children. Follow local regulations when
disposing of used batteries.
