How Long is the Warranty for BYD Batteries?

[Dale]

BYD battery warranty period is eight years or 150,000 kilometers, while the warranty for BYD new energy vehicles is six years or 150,000 kilometers. Additionally, the battery cells come with a lifetime warranty service, which is generally higher than other electric vehicle brands in the same class. Lithium iron phosphate batteries can be cycled over 2,000 times, with high charge-discharge rates and good safety performance. They generally withstand bending, high temperatures, and even punctures without issues. New energy vehicle battery packs have a lifespan, which varies depending on the materials used and daily usage conditions. For example, lithium iron phosphate batteries can be cycled over 2,000 times, with high charge-discharge rates and good safety performance, generally withstanding bending, high temperatures, and even punctures without problems. Ternary lithium batteries, widely used in new energy vehicles today, have higher energy density, resulting in better range performance and longer lifespan. In the battery field, BYD possesses 100% independent research, development, design, and production capabilities. Currently, BYD's battery products cover consumer 3C batteries, power batteries (lithium iron phosphate batteries and ternary batteries), solar batteries, and energy storage batteries, forming a complete battery industry chain.

I recently bought a new BYD car, and the salesperson told me the battery warranty is about two years, whichever comes first—like exceeding the mileage or the time limit. Once, my battery had some issues and wouldn’t start properly. I took it to the 4S store, and they checked it was still under warranty, so they replaced it with a new one for free. To be honest, the battery is pretty important. When driving, make sure not to forget to turn off the headlights or AC after turning off the engine, as that can drain the battery and shorten its lifespan. BYD’s overall warranty policy is quite considerate, but don’t expect too long for consumables like batteries. I recommend having the technician check the battery health with a device during each maintenance session to prevent issues in advance. Batteries are more fragile in cold weather, especially in winter, so paying more attention to your car’s condition can save you a lot of trouble.

When it comes to BYD's battery warranty, I think it typically covers about two years, depending on the specific model and purchase contract details. The battery plays a crucial role in the car, responsible for starting the engine and powering devices, with an average lifespan of three to four years, so BYD's warranty period is quite reasonable. I have some mechanical knowledge and understand that lead-acid batteries are prone to aging—for example, frequent short trips can lead to insufficient charging, shortening the battery's life. Replacing it after the warranty period isn't expensive, costing just a few hundred yuan. I recommend installing a battery voltage monitor to check its status on your phone and avoid sudden failures. BYD has an extensive service network, so if any issues arise, you can directly visit an authorized dealer, but don’t overlook the importance of regular maintenance.

A friend asked about BYD's battery warranty. I checked the information, and it's valid for two years. If the battery fails within two years, it's quite convenient to get a free replacement at the dealership. When buying a new car, the salesperson will definitely remind you of this, but the battery isn't expensive, so just use it normally. From my own experience, avoid listening to music for too long after turning off the engine, as that drains the battery quickly. If the battery is failing, replace it promptly to avoid the hassle of breaking down halfway. Simple maintenance can extend its lifespan, such as cleaning the battery terminals to prevent corrosion.
