What is BYD's Lifetime Battery Replacement Policy?
2 Answers
BYD's lifetime battery replacement policy offers a lifetime warranty on the three key electric components for the first individual owner (non-commercial use). Here are some relevant details about BYD: 1. Powertrain: Equipped with BYD's self-developed BYD371QA eco-friendly engine, it achieves a fuel consumption of only 4.2 liters per 100 kilometers. This inline 3-cylinder double overhead camshaft engine, paired with Bosch's electronic fuel injection system, delivers a specific power output exceeding 50kW and a maximum torque of 90 N·m. All models come standard with a 5-speed manual transmission. 2. Features: The entire lineup is equipped with ESP electronic stability program, tire pressure monitoring, as well as advanced technologies like cruise control, auto hold, and battery preheating.
When I bought the BYD electric vehicle, the salesperson introduced this lifetime battery policy, saying that the battery would degrade severely over time, such as dropping below 70% capacity or failing to charge at all, and I could get a free replacement battery. However, certain conditions must be met: the vehicle must be registered under me as the first owner, cannot be used as a taxi or ride-hailing vehicle, and must undergo annual maintenance checks at authorized service centers. I remember choosing BYD back then for this very assurance, as the biggest worry with new energy vehicles is the high cost of battery repairs. The policy also states that it only covers normal usage—if the battery is damaged in an accident or due to personal modifications, it won’t be covered. After three years of driving, the battery is still in good condition, and regular maintenance has been key. A friend of mine also bought one, but the policy became void after the ownership transfer, so I’ve been driving carefully. I think this policy is one of BYD’s major highlights.
