Does BYD still offer battery warranty after vehicle transfer?

[VonSawyer]

Second-hand BYD vehicles' batteries are eligible for the lifetime warranty. However, the battery will not be covered under the lifetime warranty policy if it sustains abnormal damage, which refers to damage caused by human factors. The battery mainly consists of the casing, power management system, cooling system, and battery cells. The primary function of the battery is to store energy. However, the power management system, cooling system, and casing are also crucial. Without these systems, the battery cannot function properly. Within the six-year warranty period, BYD will replace all the aforementioned components free of charge. Over prolonged use, the battery's capacity will gradually decrease as the number of charge and discharge cycles increases. Given the high cost of replacing new energy vehicle batteries, the ability to replace the battery for free is particularly important. To meet consumer demands, BYD offers a lifetime battery warranty policy. BYD's warranty policy is exceptionally favorable, and when the power battery's capacity degrades by 20%, it can generally qualify for a free replacement.
