Comparison between Nokia original battery and cottage battery;

1. The color of the packaging cover of the original electric appliance is dark, and it is matte paint. The assembled electrical appliances are bright in color because they contain fluorescent powder in the middle.

2. Original electric sheath, which feels good when assembled, smooth and rough.

3. There is a small point beside the contact of BL-5C, but BL-4C does not. This is very important, please pay attention.

4. When buying batteries, you can push the edge of the packaging skin with your nails. The original battery will not peel off, but the assembled battery will definitely (this is what an expert from Nokia told me)

5. The color of the original electrical contact is sub-light, not bright, and the battery has scratches after being used once.

6. Generally, the price of primary electricity will not be lower than 100. If the price is low, you should pay attention.

7, battery work: forge and imitate all letters, numbers and so on. They are all similar to the original ones, as well as battery capacity, production date and so on. Even the manufacturers are the same, except that the packaging outside the counterfeit copy is not as clear as the original, and the font is more blurred than the original, but it is not obvious, so it is easy to buy seriously unless you have a real battery comparison.

8. Holographic label: If there is a holographic label on the counterfeit Nokia BL-5C battery, it can be proved by looking at the holographic label. When you look at the holographic label, you can see the logo of Nokia's hands touching from one angle and the logo of Nokia's original accessories from another angle. When you tilt the holographic label to the left, right, down and up, you can see 1, 2, 3 and 4 dots on each side of the logo.

9 Scrape the black area on the right side of the original Nokia accessory logo, and after removing the ink on it, you should be able to see the 20-digit numbers displayed in two lines.

10. Turn the holographic label to the number area, and you should be able to read these 20 numbers. Then please go to/Nokia/0,66965, 00.html for verification. This verification can only be successfully performed once.
