If it is a pure electric vehicle, the battery can last for about 8 years, while for gasoline vehicles, the battery can last for 3 to 4 years. Below is the relevant introduction about the battery: 1. Battery Pack: The internal structure of the battery pack from top to bottom includes insulation cotton, thermal management module, insulation materials, etc., with the battery casing on the outside. Inside, there are also water-cooling heat dissipation plates and structural supports for the battery. 2. Design: Traditionally, cylindrical single cells were used, which created many gaps when stacked. After accounting for cooling supports and structural components, the space utilization rate was only 40%. The flat blade battery can reduce the ineffective gaps between single cells, and the increased surface area greatly aids in heat dissipation. After overall arrangement, the space utilization of the blade battery can reach up to 60%.

I'm a long-time BYD electric vehicle user. I've had the car for four years, driving it daily for commuting, and the battery performance remains stable. Generally, BYD batteries last about 8 to 10 years or can exceed 150,000 kilometers, which is BYD's official standard. The factors affecting battery life mainly relate to daily habits: it's best to minimize fast charging, use slow charging once or twice a week, keep the battery level between 20% and 80%, and avoid fully discharging it frequently. Temperature is crucial—during hot summers, park in the shade or use air conditioning to cool down; in winter, preheating the battery can extend its lifespan. A friend of mine has driven a BYD for five years, and the battery health is still around 85%, showing that with proper maintenance, it can last even longer. BYD's Blade Battery technology enhances safety and durability, but remember to schedule regular check-ups at the 4S店 to ensure no unexpected wear or corrosion. Battery aging varies by user, so don't worry too much—just develop good habits, and you can easily get several more years of use.

Having driven for over 20 years, switching from gasoline cars to BYD electric vehicles, I feel the battery lifespan is genuinely impressive. Officially, it's said to last 8 to 10 years or 150,000 kilometers, but actual performance depends on driving habits. In high-temperature regions, frequent exposure to direct sunlight or regular fast charging can accelerate battery degradation, potentially reducing capacity below 80% in seven to eight years. Good practices include avoiding deep discharges—don’t let the charge drop below 20% often—and prioritizing slow charging weekly. BYD's battery management excels with automatic temperature adjustments to minimize overload issues. Cost-wise, replacements are free within the warranty period, but post-warranty costs are high, so it’s wise to prioritize maintenance from day one. Long-term, EVs save money compared to gas cars, but battery lifespan directly impacts resale value—well-maintained cars can still fetch decent prices after a decade. In short, careful driving ensures lasting battery performance.

I've repaired many BYD vehicles, and owners often ask how long the battery lasts. The standard is around 8 years, but issues can arise as early as 5 years, such as reduced range, often due to poor charging habits: frequent use of fast charging overheats the battery, or failing to warm up the car in winter. BYD batteries are designed for durability, and most don't show major faults within the warranty period, but maintenance is key: slow charge once a week, keep the battery at medium charge, and don't ignore temperature effects—cooling in summer, warming in winter. Regularly check battery connections to avoid rust and corrosion; these small steps can extend lifespan. After the warranty, battery replacement is costly, but diligent maintenance can add two more years. Don't underestimate these details—they directly impact daily driving reliability.
