Battery and charger information
Your device is powered by a rechargeable battery. The battery 
intended for use with this device is BP-6MT. 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

For availability of approved accessories, please check with 
your dealer. When you disconnect the power cord of any 
accessory, grasp and pull the plug, not the cord. 
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.
