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

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.
BYD's battery warranty is truly reassuring, as I've personally experienced as an owner. They offer an 8-year or 150,000-kilometer warranty (whichever comes first) covering core components like the battery and electric motor. If you're the first owner and maintain regular service at authorized 4S shops, you can even apply for a lifetime warranty – a huge benefit for frequent drivers like me. Once when I had a minor battery issue, the service center conducted thorough checks and replaced it free of charge within just one hour. I'd advise new buyers to carefully read the manual, keep maintenance records, and not miss warranty deadlines. Additionally, proper battery maintenance is crucial: avoid excessive discharge and don't let the charge drop below 20% for extended periods when parked. This practice extends battery life, saving both hassle and money.
