Nokia Battery Authentication Guidelines - Nokia 770 User Manual

overcharging may shorten its lifetime. If left unused, a fully charged
battery will lose its charge over time.
If the battery is completely discharged, it may take a few minutes before
the charging indicator appears on the display or before any calls can be
made.
Use the battery only for its intended purpose. Never use any charger or
battery that is damaged.
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.
Leaving the battery in hot or cold places, such as in a closed car in
summer or winter conditions, will reduce the capacity and lifetime of
the battery. Always try to keep the battery between 15°C and 25°C (59°F
and 77°F). A device with a hot or cold battery may not work temporarily,
even when the battery is fully charged. Battery performance is
particularly limited in temperatures well below freezing.
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.

■ Nokia battery authentication guidelines

Always use original Nokia batteries for your safety. To check that you
are getting an original Nokia battery, purchase it from an authorized
Nokia dealer, look for the Nokia Original Enhancements logo on the
packaging, and inspect the hologram label using the following steps:
Successful completion of the four steps is not a total assurance of the
authenticity of the battery. If you have any reason to believe that your
battery is not an authentic original Nokia battery, you should refrain
from using it, and take it to the nearest authorized Nokia service point
