Battery

Battery and charger information

Your device is powered by a rechargeable battery. The battery
intended for use with this device is BL-4S. 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-3. 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.
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 59°F and 77°F (15°C and 25°C). 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. 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. 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, puncture, or
shred cells or batteries. In the event of a battery leak, prevent
battery liquid contact with skin or eyes. If this happens, flush
the affected areas 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.
Correct use. Use the battery only for its intended purpose.
Improper battery use may result in a fire, explosion, or other
hazard. If the device or battery is dropped, especially on a
hard surface, and you believe the battery has been damaged,
take it to a service center for inspection before continuing to
use it. Never use any charger or battery that is damaged. Keep
your battery out of the reach of small children.

Nokia battery authentication guidelines

Always use original Nokia batteries for your safety. To check
that you are getting an original Nokia battery, purchase it
from a Nokia authorized service center or dealer, and inspect
the hologram label using the following steps:
Successful completion of the steps is not a total assurance of
the authenticity of the battery. If you have any reason to
believe that your battery is not an authentic, original Nokia
battery, you should refrain from using it, and take it to the
nearest Nokia authorized service center or dealer for
assistance. If authenticity cannot be verified, return the
battery to the place of purchase.
