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.
For additional information, refer to the warranty and reference leaflet included with your Nokia device.
