How Many Years Are Electric Vehicle Batteries Under Warranty?
2 Answers
Electric vehicle batteries are typically under warranty for one year. These batteries are usually lead-acid batteries, and manufacturers generally provide a 15-month warranty to dealers. However, in the secondary market, the warranty period offered to users is typically one year. This is due to the time cycle involved from factory production to distribution and then to repair shops. For battery quality issues within 8 months, a new battery will be replaced. For issues occurring between 9 to 11 months, a reconditioned battery will be provided, and for issues between 12 to 15 months, a maintained battery will be offered. If there are quality issues within 8 months, a new battery can be replaced. However, if the battery damage is caused by human factors, including battery swelling that is determined not to be a quality issue after inspection, only a downgraded reconditioned battery will be provided as a replacement.
Generally speaking, the warranty period for electric vehicle batteries is mostly around 8 years, with some brands offering longer coverage. For example, Tesla provides an 8-year or 160,000-kilometer warranty, depending on the specific model and usage conditions. As an experienced EV owner, I've noticed that warranties typically cover capacity degradation below 70%. However, driving habits like frequent fast charging or prolonged parking in extreme temperatures can accelerate battery aging. If issues arise during the warranty period, manufacturers will replace the battery for free. After the warranty expires, replacing a battery pack could cost tens of thousands, making proper maintenance crucial. It's recommended to stop charging at 80% and avoid complete discharge to extend battery life. Additionally, regional climate significantly impacts battery performance, with hotter areas experiencing faster degradation—a factor worth considering in advance.
