14. Battery information
Your device is powered by a rechargeable battery. 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 Nokia-approved batteries, and recharge your
battery only with Nokia-approved chargers designated for this device.
Unplug the charger from the electrical plug and the device when not in use. Do
not leave the battery connected to a charger. Overcharging may shorten its
lifetime. If left unused, a fully charged battery loses its charge over time.
Temperature extremes can affect the ability of your battery to charge.
Always switch the device off and disconnect the charger before removing the
battery.
Check the model number of any charger before use with this device. This device is
intended for use when supplied with power from AC-1, ACP-7, ACP-8, ACP-9,
ACP-12, LCH-8, LCH-9, or LCH-12 chargers.
To prolong the battery life of NiMh batteries, discharge the battery from time to
time by leaving your device switched on until it turns itself off. Do not attempt to
discharge the battery by any other means.
Use the battery only for its intended purpose. Never use any charger or battery
that is damaged.
