What is BYD's Battery Warranty Policy?

[MacReid]

Warranty policy is 8 years or 150,000 kilometers, with battery cell lifetime warranty. BYD is currently the only new energy vehicle manufacturer in the world that offers genuine lifetime warranty for battery cells. Below is relevant information: 1. BYD Tang: The all-new Tang continues the Tang family's "Dragon-Face" design language, though there are some minor exterior detail changes compared to the gasoline and plug-in hybrid versions. The most noticeable difference lies in the front grille style. This massive matrix grille appears quite imposing, with a design resembling a soldier's armor. 2. Interior: The interior adopts the latest family-style design, featuring a simple and technological theme. It comes equipped with a three-spoke flat-bottom steering wheel, a rotatable large-size central control screen, a full LCD instrument panel, and an electronic gear lever. The functions built into the central control screen are very powerful and advanced, with aesthetically pleasing UI design and themes.

Here's what I understand about BYD's battery warranty policy: For pure electric models like the Han EV, the entire battery pack is covered for 8 years or 150,000 kilometers, with the battery cells enjoying a lifetime warranty. As for hybrid models like the Song Plus DM-i, the entire battery is also covered for 8 years or 150,000 kilometers, with the battery cells also under lifetime warranty. Note that the warranty period starts from the date of invoice. Your driving habits are quite important; if the battery abnormally degrades to below 70%, you can apply for a free replacement. However, damages caused by human factors or water-related accidents are not covered under the warranty. After registering on the official app, the vehicle's maintenance records are automatically tracked by the system.

As a long-term owner, here are a few key points to remind you: BYD's lifetime warranty for the three-electric system comes with conditions—it must be the first owner, annual mileage cannot exceed 30,000 kilometers, and accident repairs must be done at authorized service centers. I've seen cases where people didn't pay attention to these terms and ended up losing the lifetime warranty. For non-commercial vehicles, the whole vehicle warranty is 6 years or 150,000 kilometers, while core components like the motor controller are covered for 8 years or 150,000 kilometers. If you buy a used car, the warranty reduces to the basic 8 years or 150,000 kilometers. Additionally, wear-and-tear parts like tires and wipers only come with a 6-month warranty, so make sure to inspect them thoroughly when picking up the car.

Last time when helping a friend check out a car, I specifically studied the warranty details. For pure electric vehicles, the battery will be replaced free of charge if its capacity degrades below 70%, but normal degradation is not covered. There are two types of warranties: the entire power battery pack is covered for 8 years or 150,000 kilometers, while the battery cells inside have a separate lifetime warranty. For hybrid vehicles, maintenance requires attention to maintaining the HEV mileage ratio—the manual suggests running at least a few hundred kilometers on fuel each month. Remember to go to authorized service centers for maintenance during the warranty period, as even changing an air filter outside might affect the warranty. These terms are clearly outlined in Chapter 7 of the user manual.

Pro tips: Remember to get a PDI inspection at the after-sales service within 72 hours of taking delivery of your new car - missing this window may affect warranty coverage. If you notice abnormal battery swelling or a sudden range drop exceeding 30%, go straight to the 4S store for capacity testing. My colleague's Tang DM got its battery replaced for free last year, and the process went smoothly. Avoid unauthorized circuit modifications - even wiper blade replacements require documentation. Commercial vehicles have shorter warranty periods - ride-hailing drivers should note the 3-year/600,000km limit. Never use damaged charging guns in rainy conditions as water-induced short circuits count as user-inflicted damage.

There are several lesser-known facts about the practical application of warranty policies: The first owner refers to the first name on the vehicle registration certificate. If you purchase a test drive vehicle, the lifetime warranty on the three-electric system will be voided after the transfer. Battery replacement is not solely based on capacity; the voltage difference between each cell is also checked. After an insurance claim, even if it's just replacing a bumper, you must use original parts; otherwise, it will affect the warranty. For minor scratches, it's best to go to a certified body and paint center. Hybrid vehicle owners should remember to perform engine maintenance every 7,500 kilometers, as it is recorded in the system. Finally, it is recommended to register for BYD Cloud Service, where all warranty information can be conveniently checked.
