Battery information
This product uses a Lithium Polymer 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 tempera-
ture location, in strong direct sunlight, in a microwave oven or
in a pressurized container, and do not expose it to tempera-
tures 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 disas-
semble the battery. If the battery leaks and you come into con-
tact 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 bat-
tery 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 con-
nected to the AC adapter, 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
