Battery information
This product uses a Lithium 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 45° C/113° 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 may take a few minutes before the charging indicator appears on the display or
before any calls can be made.
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.
Leaving the battery in hot or cold places, such as in a closed car in summer or winter
conditions, will reduce the capacity and lifetime of the battery. Always try to keep the battery
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 particularly 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.
Replacing the battery pack
Your smartphone uses Lithium batteries. Replace the battery with the same type as that which
came bundled with your product. Use of another battery may present a risk of fire or explosion.
