Nokia battery, please do not use the battery. Take it to the nearest authorized Nokia service
point or dealer for assistance. The use of a battery that is not approved by the manufacturer

2. When you angle the hologram to the left, right, down, and up
sides of the logo, you should see 1, 2, 3, and 4 dots on each side
respectively.
3. Scratch the side of the label to reveal a 20-digit code, for
example 12345678919876543210. Turn the battery so that the
numbers are facing upwards. The 20-digit code reads starting from
the number at the top row followed by the bottom row.
4. Confirm that the 20-digit code is valid by following the
instructions at www.nokia.com/batterycheck.
To create a text message, enter the 20-digit code for example
12345678919876543210 and send to
+44 7786 200276.
National and international operator charges will apply.
You should receive a message indicating whether the code can be
authenticated.
