Matters needing attention in purchasing Tianneng battery
1, the delivery date should not exceed one month, and the delivery time is too long. On the one hand, the battery capacity is damaged, and on the other hand, the warranty given by the manufacturer to the dealer is calculated from the delivery date. If the delivery time is too long, the warranty dealer in the future will not be guaranteed.
2. Anti-counterfeiting code, check it on the website of Tianneng, or call to verify the authenticity. As long as we can find the security code, it is an authentic Tianneng battery. Tianneng's security code is in the form of scratch cards, and counterfeiters can't know the security code in advance, so they can't make it.
