■ 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. The battery should only be replaced by a qualified service
technician. 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 59°F and 77°F
(15°C and 25°C). 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.
