4. 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. 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 a fully charged battery connected to a charger, since overcharging
may shorten its lifetime. If left unused, a fully charged battery will lose its charge
over time.
Never use any charger that is damaged.
Leaving the device 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.
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.
