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 Acer approved batteries, and recharge your battery only with Acer
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 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 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.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere and
obey all signs and instructions. Potentially explosive atmospheres include areas
where you would normally be advised to turn off your vehicle engine. Sparks in
such areas could cause an explosion or fire resulting in bodily injury or even
death. Switch off the notebook near gas pumps at service stations. Observe
restrictions on the use of radio equipment in fuel depots, storage and
distribution areas; chemical plants; or where blasting operations are in progress.
Areas with a potentially explosive atmosphere are often, but not always,
marked. They include below deck on boats, chemical transfer or storage
facilities, vehicles using liquefied petroleum gas (such as propane or butane),
and areas where the air contains chemicals or particles such as grain, dust or
metal powders. Do not switch the notebook on when wireless phone use is
prohibited or when it may cause interference or danger.
Replacing the battery pack
The notebook 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.
Warning! Batteries may explode if not handled properly. Do not
disassemble or dispose of them in fire. Keep them away from
children. Follow local regulations when disposing of used
batteries.
