Nokia N900 - Manual (Page 128)

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.
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 a Nokia authorized service center or dealer, and
inspect the hologram label using the following steps:
Authenticate hologram
1
When you look at the hologram on the label, you should see the Nokia connecting
hands symbol from one angle and the Nokia Original Accessories logo when looking
from another angle.
2 When you angle the hologram left, right, down and up, you should see 1, 2, 3 and
4 dots on each side respectively.
Successful completion of the steps is not a total assurance of the authenticity of the
battery. If you cannot confirm authenticity or if you have any reason to believe that your
Nokia battery with the hologram on the label is not an authentic Nokia battery, you
should refrain from using it, and take it to the nearest Nokia authorized service center
or dealer for assistance.
