How often does a Tesla need a battery replacement?
1 Answers
Tesla requires battery replacement approximately every 8 to 10 years. Tesla battery lifespan: How often does a Tesla need a battery replacement? Tesla's battery pack is composed of over 7,000 18650 cells, and the lifespan of 18650 batteries is calculated by charge-discharge cycles, approximately 1,000 cycles. If charging every 2 days, this translates to about 2,000 days of use, meaning the battery would need replacement roughly every 5 years. Battery protection: Tesla's batteries are relatively large, offering a high range per full charge. Under the same cell cycle life, Tesla's mileage lifespan is greater. Additionally, due to the large battery capacity, the average depth of discharge by customers tends to be shallower, indirectly extending the cycle life. As for calendar life, there's no clear evaluation or official statement. However, based on current observations, Tesla's battery lifespan is likely comparable to that of the vehicle's chassis and drive system. Without external damage, mid-term battery replacement should not be necessary.
