Battery information
Charging and discharging
Your device is powered by a rechargeable battery. 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 replacement 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.
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.
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.
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.
Do not dismantle 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.
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 authorised Nokia
dealer, and inspect the hologram label using the following steps:
Successful completion of the 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 authorised Nokia service point or dealer for assistance. Your
authorised Nokia service point or dealer will inspect the battery for
authenticity. If authenticity cannot be verified, return the battery to the place
of purchase.
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 Enhancements
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.
What if your battery is not authentic?
If you cannot confirm that your Nokia battery with the hologram on the label
is an authentic Nokia battery, please do not use the battery. Take it to the
nearest authorised Nokia service point or dealer for assistance. The use of a
battery that is not approved by the manufacturer may be dangerous and
may result in poor performance and damage to your device and its
enhancements. It may also invalidate any approval or warranty applying to
the device.
