What is the content of BYD's battery warranty policy?

[Declan]

BYD's battery warranty policy can be divided into two parts: 1. First part: The battery cells are eligible for a lifetime free warranty service. A battery cell, which consists of positive electrode sheets, negative electrode sheets, and separator paper as the main materials, is an electrochemical cell that cannot be used directly. It is the smallest unit that makes up a battery pack and also the core component of a battery. 2. Second part: For components other than the battery cells, such as the casing, wires, and circuit boards, the warranty period for these parts is the same as that for the vehicle's second-class core components, which is 8 years or 150,000 kilometers.
