Charging and discharging
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
