13. 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 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.
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.
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
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.
