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 call and standby times are
noticeably shorter than normal, buy a new battery. Use only
Nokia approved batteries. In addition, recharge your battery
only with Nokia approved chargers designated for this device.
Always switch the device off and disconnect the charger
before removing the battery.
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.
