Nokia Battery Authentication Guidelines - Nokia 6790 Surge Guia Del Usuario

Unplug the charger from the electrical plug and the device when not in use. Do not leave
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.
Always try to keep the battery between 15ºC and 25ºC (59ºF and 77ºF). 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 the battery. 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.
Do not dispose of batteries in a fire as they may explode. Batteries may also explode if
damaged. Dispose of batteries according to local regulations. Please recycle when possible.
Do not dispose as household waste.
Do not dismantle, cut, open, crush, bend, deform, puncture, or shred cells or batteries. In the
event of a battery leak, do not allow the liquid to come in contact with the skin or eyes. In
the event of such a leak, flush your skin or eyes immediately with water, or seek medical
help.
Do not modify or remanufacture, attempt to insert foreign objects into the battery or
immerse or expose it to water or other liquids.
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.
Use the battery only for its intended purpose. Never use any charger or battery that is
damaged. Keep your battery out of the reach of small children.
