Batteries and chargers
Battery and charger information
This device is intended for use with a BL-5K rechargeable
battery. Nokia may make additional battery models
available for this device. Always use original Nokia batteries.
This device is intended for use when supplied with power
from the following chargers: AC-15 . The exact charger
model number may vary depending on the type of plug. The
plug variant is identified by one of the following: E, X, AR, U,
A, C, K, or B.
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, you need

Battery safety
Always switch the device off and disconnect the charger
before removing the battery. When you unplug a charger or
an accessory, hold and pull the plug, not the cord.
When your charger is not in use, unplug it from the electrical
plug and the device. Do not leave a fully charged battery
connected to a charger, as overcharging may shorten the
battery's lifetime. If left unused, a fully charged battery will
lose its charge over time.
Always 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.
Accidental short-circuiting can happen when a metallic
object touches the metal strips on the battery, for example,
if you carry a spare battery in your pocket. Short-circuiting
may damage the battery or the connecting object.
Do not dispose of batteries in a fire as they may explode.
Dispose of batteries according to local regulations. Recycle
when possible. Do not dispose as household garbage.
Do not dismantle, cut, open, crush, bend, puncture, or shred
cells or batteries. If a battery leaks, do not let battery liquid
touch skin or eyes. If this happens, immediately flush the
affected areas with water, or seek medical help.
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.
Use the battery and charger for their intended purposes
only. Improper use, or use of unapproved batteries or
chargers may present a risk of fire, explosion, or other
hazard, and may invalidate any approval or warranty. If you
believe the battery or charger is damaged, take it to a
service center for inspection before continuing to use it.
