14. Battery information
This section provides information about batteries, chargers, safety guidelines and
technical information. Be aware that the information in this section is subject to
change as batteries and chargers change.
■ Charging and discharging batteries
Your phone 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
phone.
Unplug the charger from the electrical plug and the phone 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 59°F and 77°F (15°C and
25°C). A phone 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.
