How long is the battery life of Tesla Model 3?

[VonJune]

Tesla's official data on battery lifespan is 450,000 to 600,000 kilometers, approximately usable for about 20 years. In reality, electric vehicle batteries are not that fragile at all. Domestic policies stipulate that electric vehicles should provide an 8-year or 150,000-kilometer warranty for the battery. Here is the relevant introduction: Battery: Tesla's unit battery consists of over a dozen small packs, and each small pack is composed of more than seventy batteries. The higher the electric vehicle's range and the larger the battery capacity, the more expensive the battery. Battery replacement cycle: Tesla's battery pack is composed of over 7,000 18650 batteries, and the lifespan of 18650 batteries is calculated by charge-discharge cycles, approximately 1,000 times. If charged once every 2 days, it can be used for about 2,000 days, which means the battery needs to be replaced approximately every 5 years. Of course, the actual usage depends on the specific condition of the vehicle.
