What is the battery replacement standard for BYD battery degradation?

[StMalia]

When the battery capacity falls below 66% of the standard capacity, a new battery replacement is directly required. Here are the relevant details: 1. BYD: BYD is a Chinese automotive brand established in 1995, primarily manufacturing commercial vehicles, passenger cars, and batteries. Starting with a team of just over 20 people, it grew into the world's second-largest rechargeable battery manufacturer by 2003. In the same year, BYD Auto was established, adhering to a development strategy of independent R&D, production, and branding, with the goal of creating truly affordable and high-quality vehicles for the general public. 2. Pure Electric Vehicles: Pure electric vehicles are powered by an onboard power source, using electric motors to drive the wheels, and comply with all road traffic and safety regulations. Due to their relatively lower environmental impact compared to traditional vehicles, their prospects are widely viewed as promising, though the current technology is still not fully mature.

I've been driving a BYD electric car for several years, and BYD has clear standards regarding battery degradation. Their official warranty typically covers 8 years or 150,000 kilometers, with free battery replacement if the capacity drops below 70%. You need to visit a 4S store for professional testing, using specialized equipment to measure battery health. In daily use, pay attention to reduced range—for example, if it used to run 400 kilometers but now only manages 280, it's time for a check-up. Don't wait until it's completely dead, as severe degradation affects driving safety and charging efficiency. It's recommended to perform battery maintenance every six months, including balanced charging to extend lifespan. If the warranty expires, battery replacement can be costly, but BYD services are transparent—they'll present a solution before you decide.

As a long-term BYD user, I've found that battery degradation replacement mainly depends on the warranty terms. My car's battery degraded to 65% within the warranty period, and the 4S store replaced it for free. The standard is that you can apply when capacity falls below 70%, but it must be confirmed by official testing. Never make assumptions yourself - for example, reduced range could just be due to cold winter winds, not actual degradation. BYD's after-sales service is quite good, with the process taking about a week. Remember to keep maintenance records, as this can save trouble. After warranty expires, you'll have to pay out of pocket, which could cost tens of thousands, so pay attention to warranty details when buying. When driving an EV daily, avoid frequent full charges and complete discharges to reduce aging.

BYD's battery replacement criteria are quite practical, with the key being the warranty policy. During the warranty period (e.g., 8 years), you can get a free replacement if the battery health drops below 70%. This requires an official inspection—you can't just rely on the dashboard showing reduced range. I've researched this, and post-warranty replacements can be costly, costing tens of thousands, so it's advisable to get a checkup before the warranty expires. BYD has an extensive service network, making appointments convenient. Don't overlook this, as severe degradation could lead to sudden breakdowns, affecting safety. Using slow charging more often than fast charging during maintenance can help delay the issue.
