Is the battery of BYD electric vehicles covered by a lifetime warranty?

BYD electric vehicles offer a lifetime warranty for the battery cells, not the entire battery. Here is an extended explanation: Power battery and battery cells are not the same: A power battery includes battery cells and other components (such as connecting wires, circuit boards, connectors, casings, etc.). Warranty and free repair are not the same: The warranty period, also known as the three-guarantee validity period, is stipulated by the state to be no less than 2 years or 50,000 kilometers, during which conditional returns or exchanges are possible (specific terms can be found in the "Regulations on the Liability for Repair, Replacement, and Return of Household Automotive Products"). Generally, automakers avoid using the term "warranty" and instead specify the duration of the free repair period. Free repair refers to the period during which repairs are provided at no cost, but returns or exchanges are not permitted.
