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.
