Battery and charger info
Your device is intended for use with a
BL-4U 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-11. The exact
Nokia charger model number may
vary depending on the plug type,
identified by E, X, AR, U, A, C, K, B, or
N.
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.
Important: Talk and standby
times are estimates only. Actual times
are affected by, for example, network
conditions, device settings, features
being used, battery condition, and
temperature.
Battery safety
Always switch the device off and
unplug 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.
