Tesla batteries are designed to last between 300,000 and 500,000 miles, which typically translates to about 8 to 15 years of use depending on driving habits and conditions
. Tesla CEO Elon Musk has mentioned that their batteries can endure about 1,500 full charge cycles, supporting this mileage range
. In terms of degradation, Tesla batteries lose roughly 1% of their capacity per year, meaning after 10 years they often retain about 90% of their original capacity
. Real-world data shows that after 200,000 miles, Tesla Model S and Model X batteries degrade by about 12%, and after 322,000 km (roughly 200,000 miles), Tesla Model 3, Model Y, and Model X retain around 88% of their original capacity
. Tesla offers an 8-year battery warranty that covers 100,000 to 150,000 miles depending on the model, guaranteeing at least 70% battery capacity retention during that period
. For example, the Model S and X warranties cover 8 years or 150,000 miles, while the Model 3 and Model Y warranties cover 8 years or 100,000 to 120,000 miles
. Battery life can be affected by factors such as frequent fast charging, extreme temperatures, and driving style, but Tesla’s battery management system helps mitigate these effects
. Proper care can extend battery longevity closer to the upper end of the expected lifespan. In summary:
- Tesla batteries last approximately 300,000 to 500,000 miles or about 8–15 years
- Battery capacity typically degrades about 1% per year, retaining ~90% capacity after 10 years
- Tesla warranties cover 8 years or 100,000–150,000 miles with at least 70% capacity retention guaranteed
- Real-world data shows Tesla batteries maintain good capacity well beyond 200,000 miles
This makes Tesla batteries among the longest-lasting in the electric vehicle market today.
