How Many Years Can an Electric Vehicle's 8-Year Warranty Actually Last?

Lithium iron phosphate batteries are characterized by: strong safety, long lifespan, and high stability at elevated temperatures. Theoretically, a single cell can achieve 100% deep cycling up to 5,000 times, with a maximum service life of 10 years. In practice, around 2,000 charge-discharge cycles are generally trouble-free, allowing usage for 5-8 years. Signs of a failing vehicle battery include: 1. Difficulty starting the car: If the car suddenly becomes hard to start without other factors, it may be a sign of impending battery failure. 2. Dimming lights at idle: For example, when stopped at a red light or temporarily parked, the headlights may suddenly dim due to reduced charging power from the engine at idle. 3. Battery warning light illuminates: When the battery warning light comes on, it alerts the owner to have the battery inspected at a repair shop. 4. Normal driving but occasional complete power loss after parking and restarting: This occurs when the battery's end-of-life results in insufficient starting current, increasing oxide buildup on the terminals and causing a total power loss.
