Is the county name and production date printed on Tianneng battery box authentic?

There is no guarantee that the county name and production date are true. The identification method is as follows:

1, it depends on whether the battery packaging of the electric vehicle is damaged or there are signs of disassembly, then open the packaging to see the appearance of the battery, see if there are scratches and abrasions on the surface, and then see if there are signs of corrosion on the metal terminals of the positive and negative electrodes of the battery. The surface of the original battery must be novel.

2. Many brands of electric vehicle batteries will be affixed with anti-counterfeiting labels at the butt joint of the battery shell when they leave the factory. Pay attention to see if the original anti-counterfeiting label is normal. You can also scrape off the password coating of the anti-counterfeiting label to verify the authenticity.

3. Just look at the production date and warranty card printed on the battery of the electric vehicle. Under normal circumstances, regular electric vehicle battery products will have these two things, especially the warranty card is an effective way to solve the problem when there is a problem with the product, and the product without the warranty card is definitely a fake.
