This section provides information about your phone’s 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, 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 after the battery has finished charging.
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.
