136 Product and safety information
AC-10. 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.
Correct use. Use the battery only for its intended purpose. Improper battery use may
result in a fire, explosion, or other hazard. If the device or battery is dropped, especially
on a hard surface, and you believe the battery has been damaged, take it to a service
centre for inspection before continuing to use it. Never use any charger or battery that
is damaged. Keep your battery out of the reach of small children.
