Tesla Battery Warranty: What's Covered and What's Left Used
Every Tesla battery is covered for 8 years, with a mileage cap of 100,000, 120,000 or 150,000 miles depending on the model, and a promise that capacity will not fall below 70 percent. The clock starts on the first delivery date, not the model year, so a used car carries whatever is left. Since December 2025, Model 3 and Model Y owners can buy two more years for 2,000 dollars, but only before the original warranty ends, and that extension does not cover capacity loss at all.
