The cost of replacing an electric car battery is one of the most shocking aspects of EV ownership. Depending on the model, replacement can cost anywhere from $5,000 to $20,000 or more. For many owners, this is almost as expensive as buying a new car. While warranties cover the battery for several years, once the warranty period ends, drivers are left with a massive expense if the battery fails. Some brands have better long-term performance, but the risk remains. This is a major factor that affects resale value as well, since buyers are afraid of taking on that cost. Owners often share their frustration online, pointing out that while EVs are marketed as cheaper to run, the potential of such an expensive repair makes them financially risky. Clearer information about long-term battery costs would help buyers make informed decisions.
