Battery and charger information
Your device is powered by a rechargeable battery. The battery intended for use with this device is BL-4CT. 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.
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. 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.
