How much does it cost to replace a battery in an electric car?

According to data from industry researchers Recurrent Auto, battery replacements are incredibly rare, with only about 1.5 percent of EVs needing actual replacements – and almost all of those replacements being done under warranty. (Battery warranties are generally eight to 10 years.) The actual cost of a complete replacement battery can be very high – in the tens of thousands of dollars – but most manufacturers are now training special service technicians to repair batteries by replacing faulty cells, instead of the entire battery pack.
