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 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.
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. 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! Dispose of batteries
according to local regulations. Please recycle when possible. Do
not dispose as household waste.
