What are the battery replacement conditions for the 2015 BYD Tang?

[VanEmilia]

BYD Tang uses lithium iron phosphate batteries with a warranty condition of 8 years or 150,000 kilometers. Below is detailed information about the BYD Tang: 1. Overview: BYD officially launched the "Tang" SUV in Shenzhen on January 20, 2015. The front features a completely new design, including large chrome accents, a black honeycomb grille, and a "big mouth" style air intake on the front bumper. 2. Powertrain: The BYD Tang is equipped with a three-engine dual-mode powertrain system, consisting of a 2.0TI turbocharged engine and front/rear electric motors, enabling independent power output for front and rear wheels. In hybrid mode, all three "engines" work simultaneously, delivering maximum power of 371Kw and peak torque of 720Nm.

I've been driving the BYD Tang 2015 model for several years. The main condition for battery replacement is significant degradation in range due to battery aging. After driving this car for 70,000 to 80,000 kilometers, the pure electric range dropped from 80 kilometers to just over 50. When charging, checking the app showed a degradation of over 30%, which is basically the signal. BYD's original warranty covers 8 years or 150,000 kilometers, offering free battery replacement, but only after inspection at an authorized service center. Daily attention should be paid to charging speed and driving stability. If the dashboard shows a warning light or there's a noticeable lack of acceleration, it's time to consider a replacement. Cost-wise, replacing the battery out of warranty can cost around 10,000 yuan, which is quite expensive. It's recommended to minimize fast charging to protect battery lifespan. In short, don't delay; regular maintenance can help avoid trouble.

I have some knowledge about car maintenance, and driving a BYD Tang hybrid requires understanding the battery status. The conditions for battery replacement aren't just based on mileage; you also need to use diagnostic tools to check its health. If the capacity drops below 80%, it's considered risky. During the warranty period, replacements are free, but the 4S shop will check the charge-discharge cycles and voltage fluctuations. After the warranty expires, you'll need to replace it when the degradation affects pure electric driving or causes hybrid switching failures. Maintenance is key—avoid overcharging and over-discharging to extend its lifespan. I often monitor it with an OBD device. If the range drops by more than 20% or the charging time doubles, it's time to act. Self-funded replacements are costly, requiring a budget of several thousand, but safety comes first—don't take it lightly.

I carefully calculate car maintenance costs, with BYD Tang's battery replacement conditions focusing on economic benefits. The warranty offers free replacement within 8 years, but severe degradation like halved range affecting daily commutes is the real trigger point. Otherwise, stretching a few more years saves money since new batteries cost tens of thousands. Check via App for degradation over 25% or charging abnormalities, then visit the shop for evaluation. If power drops too fast or performance becomes unstable, replace immediately—don't risk major faults to save small money. Gentle driving and slow charging can delay replacement, being both economical and reassuring.

I prioritize driving safety and drive a BYD Tang hybrid. The condition for battery replacement is key to preventing accidents. When battery degradation affects the power supply system, such as interruptions in pure electric mode or dashboard warnings, immediate replacement is necessary. Faults are handled for free within the warranty period; post-warranty, safety tests like capacity tests must be acted upon if they fail. Maintenance includes regular checks on battery levels and temperature to avoid the risk of spontaneous combustion. I once experienced sudden power loss and felt much more at ease after a timely replacement. Don't wait for small issues to escalate—cost and convenience are secondary, safety is the primary guarantee of life.
