How long do electric car batteries last?

The battery pack in an electric vehicle is made to last the lifetime of the vehicle. However, they do slowly lose the amount of energy they can store over time. This phenomenon is called “battery degradation.” You can limit battery degradation by only using Level 3 charging infrequently, and reducing exposure to extreme temperatures.Battery replacements are vanishingly rare, with only about 1.5 percent of EVs needing actual replacements, and because of the long eight- or 10-year battery warranties, these replacements are generally covered by the manufacturer. Many manufacturers are now training technicians to repair faulty cells in battery packs instead of completely replacing them.
