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 authorised service centre or 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 Nokia authorised service centre or dealer for
assistance. If authenticity cannot be verified, return the
battery to the place of purchase.
