18. Battery information

Charging and discharging

Your device is powered by a rechargeable battery. 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.
If a replacement battery is being used for the first time or if the battery has not been
used for a prolonged period, it may be necessary to connect the charger, then disconnect
and reconnect it to begin charging the battery.
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.
If the battery is completely discharged, it may take several minutes before the charging
indicator appears on the display or before any calls can be made.
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
