• BATTERY STATEMENTS
Charging and Discharging
Your phone is powered by a rechargeable battery.
Note that a new battery's full performance may be 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. 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.
For good operation times with NiMh batteries, discharge the battery from time
to time by leaving your phone switched on until it turns itself off (or by using the
battery discharge facility of any approved accessory available for your phone).
