EV batteries hold up much better than in smartphones. Data from Teslas shows 1%-2% degradation per year (so you can expect to have 80%+ of range after 10 years)

EV batteries hold up much better than in smartphones. Data from Teslas shows 1%-2% degradation per year (so you can expect to have 80%+ of range after 10 years). Leaf fares worse (~4% per year), but it only has air-cooled battery. Tesla and other modern EVs have active battery management system that heats and cools the battery to keep it in the right temperature range. Replacement is costly, unfortunately. It's the most expensive component of an electric car.
