How Many Years Can the BYD e5 Battery Last?
1 Answers
The BYD e5 uses a ternary lithium battery. Due to the chemical properties of ternary lithium batteries, their capacity naturally degrades over time, leading to a reduction in driving range. According to the manufacturer's guidelines, the power battery should be replaced entirely after 8 years or 150,000 kilometers, while the battery cells are covered by a lifetime replacement warranty (for 1, 2, or 3 sets). Proper usage and maintenance can extend the lifespan of the BYD e5 power battery: 1. Regularly use charging equipment to fully charge the power battery (it is recommended to perform a full charge at least once a week). 2. When storing the vehicle unused for an extended period: Always charge the battery to 100% first, then discharge it to between 30%-40%. If the storage period exceeds three months, the battery must be recharged; otherwise, it may lead to over-discharge, reducing battery performance. 3. Charge the battery when the power level drops to the warning red mark: This ensures that the vehicle does not run out of power and become stranded. It is not recommended to charge the battery only after it is completely depleted, as this can negatively impact the battery's lifespan.
