Is BYD Battery Replacement Free?

[VonMason]

BYD offers free battery replacement for life. As long as the battery degradation reaches 20%, you can go to a 4S store for a free replacement. Of course, after 8 years, additional labor fees will be charged, but the battery itself remains free. Below is some relevant information: Battery: In terms of batteries, the BYD Han pure electric version uses BYD's self-developed Blade Battery (lithium iron phosphate battery), which not only has excellent energy density but also provides good safety guarantees. After all, it is currently the only battery that can pass the nail penetration test. It also supports fast charging technology, taking only 0.42 hours to fast charge to 80%. Reasons for lifetime free replacement: There are three reasons. The first is the trend of new energy vehicles, the second is a matter of capability, and the third is to give consumers confidence in new energy vehicles and eliminate concerns about subsequent battery replacement costs. Moreover, new energy vehicles also come with purchase subsidies and do not cause emission pollution to the environment, which is the trend.

I'm a BYD new energy vehicle owner, and it's been almost four years since I bought the car. Recently, I noticed a significant drop in range—it couldn't even last half the distance on a full charge. After taking it to the 4S store for inspection, I found out it was a battery issue. The service staff informed me that BYD batteries come with an eight-year or 150,000-kilometer warranty, covering free replacement for non-manufacturing defects within the warranty period. My car had driven less than 50,000 kilometers, so it was still under warranty, and they replaced the battery for free. The whole process went smoothly without costing me a penny, and I felt BYD's service was quite considerate. I recommend other owners who encounter similar issues not to hesitate and directly contact an authorized service center for inspection. Remember, once the warranty expires, battery replacements will have to be paid out of pocket, reportedly costing tens of thousands. Also, pay extra attention to battery health during regular maintenance to avoid unexpected issues.

I often help friends with car repairs and maintenance. BYD's battery replacement is indeed free within the warranty period. Specifically, their battery warranty generally covers eight years or a specified mileage. If quality issues are detected, such as significant capacity degradation or functional abnormalities, the 4S dealership will replace it for free. However, be cautious about damage caused by human factors, such as collisions or unauthorized modifications to the charging system, as those may not be covered. I think as a car owner, it's important to regularly check the battery's performance—you can use the app to view health reports. If you notice anything unusual, take it to a service center early to avoid further deterioration. Also, replacing the battery after the warranty expires could cost 10,000 to 20,000 yuan, so it might be better to choose a brand with a longer warranty when buying the car. In short, free replacement is a great benefit, but don't wait until the warranty expires—your wallet might suffer later.

From a cost-saving perspective, the expense of replacing a battery isn't cheap. If a BYD vehicle's battery fails within the warranty period, getting a free replacement can save a significant amount of money. Based on my experience, the battery warranty covers eight years, and any issues within the first five years under normal driving conditions are usually covered for free. Last year, a friend's car had its battery degrade to only half its original range, and after inspection, it was replaced at no cost. However, if the warranty expires or maintenance isn't performed on time, you might have to pay tens of thousands out of pocket. So, I strongly recommend thoroughly understanding the warranty terms when buying a new car and keeping all records. BYD is quite reliable in this regard. Additionally, don't just focus on the free benefits—consider future costs as well, and choose a reputable brand from the start.
