How Often Should BYD Batteries Be Replaced?
2 Answers
If it is a pure electric vehicle, the battery can last for about 8 years. If it is a gasoline-powered vehicle, the battery can last for 3 to 4 years. Here is some relevant information about the battery: 1. From top to bottom, the battery pack internally consists of insulation cotton, thermal management modules, insulation materials, etc., with the battery casing on the outside. Inside, there are also water-cooled heat dissipation plates and structural supports for the battery. 2. Traditionally, cylindrical-shaped single cells were used, which left many gaps when stacked. After accounting for cooling supports and structural components, the space utilization rate was only about 40%. The flat blade battery can reduce the ineffective gaps between single cells, and the increased surface area also plays a significant role in heat dissipation. After overall arrangement, the space utilization of blade batteries can reach up to 60%.
I've been driving a BYD electric car for three years, starting with the Han model, and the battery performance has been consistently good. I haven't heard of any specific number of years when it must be replaced—it really depends on individual usage. Among my friends who drive BYD, some have driven for seven or eight years before the battery degraded to 80% capacity, at which point replacement or repair might be needed. Factors affecting this include driving habits, charging frequency, and environmental temperature. Frequent long-distance driving or fast charging can accelerate degradation, but with normal city use, you might not need a replacement for up to ten years. BYD's official warranty usually covers eight years or 120,000 kilometers, meaning if there's a serious battery issue within eight years, you can get a free replacement. My advice is to regularly check the battery health using the vehicle diagnostic tool and avoid over-discharging to maximize battery life beyond ten years. It saves money and hassle.
