18. Battery and charger information
Your device is powered by a rechargeable battery. The battery intended for use with this
device is BL-4U. Nokia may make additional battery models available for this device. This
device is intended for use when supplied with power from the following chargers: AC-8.
The exact charger model number may vary depending on the type of plug. The plug variant
is identified by one of the following: E, EB, X, AR, U, A, C, K, or UB.
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 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, then disconnect and reconnect it to
begin charging the battery. If the battery is completely discharged, it may take several
minutes before the charging indicator appears on the display or before any calls can be
made.
Battery Safety. Safe removal. Always switch the device off and disconnect the charger
before removing the battery.
Proper charging. 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.
Avoid extreme temperatures. Always try to keep the battery between 15°C and 25°C (59°F
and 77°F). Extreme temperatures reduce the capacity and lifetime of the battery. A device
with a hot or cold battery may not work temporarily. Battery performance is particularly
limited in temperatures well below freezing.
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.
Disposal. 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.
Leak. Do not dismantle, cut, open, crush, bend, deform, puncture, or shred cells or batteries.
In the event of a battery leak, do not allow the liquid to come in contact with the skin or
eyes. In the event of such a leak, flush your skin or eyes immediately with water, or seek
medical help.
Damage. Do not modify, remanufacture, attempt to insert foreign objects into the battery, or
immerse or expose it to water or other liquids. Batteries may explode if damaged.
