What are the conditions for BYD's battery lifetime warranty?

[LeviLee]

BYD's battery lifetime warranty conditions include: Only the first owner of the vehicle is eligible for the lifetime warranty on the three key components (battery, motor, and electronic control); Maintenance must be performed at authorized service centers within the intervals specified in the user manual; Only genuine BYD parts must be used for repairs and maintenance; Registration on BYD Cloud Service and DiFan Club is required; The vehicle must not have been driven continuously for 12 months or exceed a total mileage of 30,000 kilometers; Accident repairs must be conducted at BYD-authorized service centers; Normal battery capacity degradation applies. Currently, BYD's battery warranty policy offers a lifetime warranty on the three key components for the first individual owner (non-commercial use), while the vehicle's overall warranty policy covers 6 years or 150,000 kilometers. For the three key systems, BYD provides a lifetime warranty. Additionally, BYD's battery degradation replacement standard is a degradation exceeding 30% during the warranty period. According to the "BYD Vehicle Warranty and Maintenance Service Manual" provided with the vehicle, the warranty period for the power battery (including only the battery cells, BIC, and cooling circuit), front and rear drive motors, and front and rear drive motor controllers is lifetime.

Speaking of BYD's lifetime battery warranty, as one of their car owners, I've personally experienced this. The conditions are quite clear: you must be the first owner of the vehicle, meaning you can't resell the new car and still enjoy the warranty. The vehicle cannot be used for commercial operations, such as ride-hailing or taxi services, and must be purely for private use. Maintenance is key here—it must be strictly performed according to the manual at BYD-authorized service centers on schedule. Don't skip and go to small repair shops casually. I once almost missed a maintenance deadline, but thankfully the after-sales service reminded me in time. If the battery capacity drops below 70%, they can replace it for free after inspection, but only if it's due to normal degradation or original factory defects. Modifying the battery is strictly prohibited, such as installing additional electrical devices yourself, which could void the warranty. Keep these points in mind, and you can enjoy this benefit with peace of mind.

From a technical perspective, BYD's battery lifetime warranty is quite scientifically designed. The conditions include that it only applies to the first private owner, and the vehicle cannot be used for commercial purposes. The maintenance requirements are very strict: it must be performed at authorized dealers every 10,000 kilometers or according to the owner's manual schedule—don't think about saving money by doing it yourself. For the battery, free replacement is only triggered when the capacity degrades below 70% and is confirmed by official testing. This warranty covers faults under normal use, excluding accidental collisions or human-caused damage, such as long-term improper charging. There are also additional clauses: do not disassemble or modify the battery system without authorization, and avoid using it in non-recommended environments, such as prolonged parking in extreme temperatures. Familiarizing yourself with these terms ensures your rights are protected.

For regular users, BYD's battery lifetime warranty is a great money-saving tool, but don't miss the conditions. You must be the first owner, and the car must be for private use only—no renting it out for profit. Maintenance must be done at authorized shops, and don't delay regular check-ups. If the battery capacity drops below 70%, you can get a replacement, saving a big expense. A reminder: don't make unauthorized modifications, like installing non-official accessories, as the warranty could be voided. Stick to the manual, and it will be cost-effective in the long run.

BYD's battery lifetime warranty emphasizes safety and maintenance. I personally pay great attention to this: the vehicle must be the first private owner and not used for commercial purposes. Maintenance must be strictly periodic and handled at authorized service centers to prevent accidents. For example, my friend almost lost the warranty because maintenance was delayed by two weeks. Do not modify any components to avoid safety hazards. The battery can be replaced if its capacity falls below 70%, but it requires an official inspection. Always charge through official channels, as proper maintenance can enhance overall lifespan.

Long-term ownership of BYD comes with a battery lifetime warranty for peace of mind. Conditions apply: must be the first owner and limited to private vehicle use. Do not interrupt maintenance; visit authorized service centers on schedule—skipping may jeopardize the warranty. Free battery replacement is available if capacity drops below 70% under normal degradation, ensuring value retention and safety. Avoid any modifications or misuse, such as overloading or improper charging. Maintaining good records enhances resale value, making it a worthwhile commitment.
