6. Battery information
■ Charging and Discharging
Your device is powered by a rechargeable battery. 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, take the device to an authorized service to replace
the old 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 will lose its charge over time. Temperature extremes can affect the ability of
your battery to charge.
Use the battery only for its intended purpose. Never use any charger or battery that is
damaged.
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.
