Nokia Battery Authentication Guidelines - Nokia 2730 classic User Manual

66 Battery
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 59°F and
77°F (15°C and 25°C). 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 center 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.
