• BATTERIES, CHARGERS, AND ACCESSORIES

This section provides information about the phone's batteries, accessories,
and chargers. Be aware that the information in this section is subject to
change as the batteries, chargers, and accessories change.
Check the model number of any charger before use with this device.
Note: For information on how to charge and recharge your battery,
refer to "Charge the battery" on page 11.

Charging and Discharging

Your phone is powered by a rechargeable battery.
Note that a new battery's full performance 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 operating time (talk-time and standby
time) is noticeably shorter than normal, it is time to buy a new battery.
Use only batteries approved by the phone manufacturer and recharge
your battery only with the chargers approved by the manufacturer.
18
Unplug the charger when not in use. Do not leave the battery connected
to a charger for longer than a week, since overcharging may shorten its
lifetime. If left unused, a fully charged battery will discharge itself over
time.
Temperature extremes can affect the ability of your battery to charge.
Allow it to cool down or warm up first.
Warning: Use only batteries, chargers and accessories approved by
the phone manufacturer for use with this particular phone model.
The use of any other types may invalidate any approval or warranty
applying to the phone, and may be dangerous. For availability of
approved accessories, please check with your dealer.
