Battery information
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 begin charging the battery.
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.
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.
The BL-5BT battery provides up to 140 minutes (WCDMA) /
180 minutes (GSM) of talk time, and up to 230 hours
(WCDMA) / 240 hours (GSM) of standby time. Battery talk and
standby times are estimates only and depend on signal strength,
network conditions, features used, battery age and condition,
temperatures to which battery is exposed, and many other
factors. The amount of time a phone is used for calls will affect
its standby time. Likewise, the amount of time that the phone
is turned on and in standby mode will affect its talk time.
