15. Reference information

This section provides information about your phone batteries, enhancements,
chargers, safety guidelines, and technical information. Be aware that the information
in this section is subject to change as batteries, chargers, and enhancements change.

■ Batteries and chargers

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,
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 and
then disconnect and reconnect it to start the charging.
Unplug the charger from the electrical plug and the device when not in use. Do not
leave 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 a few 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 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.
