Battery information
This product uses a Lithium-ion battery. Do not use it in a
humid, wet and/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 low (below 0 °C/32 °F) or
high (over 40 °C/104 °F) temperatures.
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 talk and standby times
are noticeably shorter than normal, buy a new battery. Use
only Acer approved batteries, and recharge your battery only
with Acer approved chargers designated for this device.
Unplug the charger from the electrical plug and the device
when not in use. Do not leave a fully charged battery
connected to the ac charger, since overcharging may shorten
its lifetime. If left unused, a fully charged battery will lose its
charge over time. If the battery is completely discharged, it
