19. Battery information
■ Charging and discharging
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, replace the 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 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.
Use the battery only for its intended purpose. Never use any charger or battery that is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object such as a coin, clip, or pen
causes direct connection of the positive (+) and negative (-) terminals of the battery. (These look like metal strips on the
battery.) This might happen, for example, when you carry a spare battery in your pocket or purse. Short-circuiting the
terminals may damage the battery or the connecting object.
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 and its ability to charge. 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.
