This device is intended for use when

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

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.
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 waste.
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

incompatible chargers may present a

risk of fire, explosion, or other hazard,
