Batteries and chargers
Nokia battery authentication guidelines
Always use original Nokia batteries for your safety. To help
ensure that you are getting an original Nokia battery,
purchase it from a Nokia authorized service center or dealer,
and check the hologram label.
Authenticate hologram
1 Look at the hologram. You should see the Nokia
connecting hands symbol from one angle and the Nokia
Original Accessories logo from the other angle.
Product and safety information
2 Angle the hologram left, right, down, and up. You
should see 1, 2, 3 and 4 dots on each side respectively.
However, this 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, stop
using the battery and take it to the nearest Nokia authorized
service center or dealer.
For additional information, refer to the warranty and
reference leaflet included with your Nokia device.
Battery and charger information
This device is intended for use with a BL-5K rechargeable
battery. Nokia may make additional battery models available
for this device. Always use original Nokia batteries.
This device is intended for use when supplied with power
from the following chargers: AC-15 . The exact charger model
number may vary depending on the type of plug. The plug
variant is identified by one of the following: E, X, AR, U, A, C,
K, or B.
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, you need
to replace the battery.

the IEEE-std-1725-200x standard.
Battery safety
Always switch the device off and disconnect the charger
before removing the battery. When you unplug a charger or
an accessory, hold and pull the plug, not the cord.
When your charger is not in use, unplug it from the electrical
plug and the device. Do not leave a fully charged battery
connected to a charger, as overcharging may shorten the
battery's lifetime. If left unused, a fully charged battery will
lose its charge over time.
Always keep the battery between 15°C and 25°C (59°F and
77°F). Extreme temperatures reduce the capacity and lifetime
of the battery. A device with a hot or cold battery may not
work temporarily.
