How to distinguish between new batteries for electric vehicles, turnover batteries, and maintenance batteries?

First of all, if divided by type, it can be divided into original batteries and after-sale batteries, while original batteries are new batteries, and after-sale batteries include revolving batteries and maintenance batteries. Under normal circumstances, if the original battery fails within 8 months, the new battery will be replaced directly; and if the failure occurs more than 8 months and not more than 1 year, the replacement battery will be the revolving battery; and if it exceeds 1 year and If there is a failure in less than 15 months, then the replacement will be the maintenance battery. Secondly, according to performance points, new batteries have the best performance, turnover batteries are the second, and maintenance batteries are the worst. Why do you say that? Because the new battery is the original battery, the revolving battery is the battery to be repaired during the first stage of failure, and the maintenance battery is the battery to be repaired during the second stage of failure, so the new battery is better than the revolving battery and the maintenance battery. Finally, if it is divided by appearance packaging, the new battery does not have any traces of polishing, and it has a series of certifications such as a certificate of conformity, a quality assurance card, and a date of manufacture. The packaging of turnover batteries and maintenance batteries will have the words turnover and maintenance. Regarding the user, when choosing, they can be carefully identified to avoid wrong selection. Of course, some brand batteries also have their own security codes. For the user, you can check the authenticity yourself. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
