Federal regulation in the U.S. also mandates that electric car batteries be covered under the manufacturer’s warranty for at least 8 years, but most EV batteries last nearly 20 years on average. This means that they aren’t being replaced on a yearly basis.
In addition, the price for an electric car’s battery can cost somewhere between $5,000-15,000, similar to having a transmission replaced in a standard vehicle. The best way to ensure that your battery lasts as long as possible is to avoid exposing your EV to extreme temperatures, and to keep Level 3 fast-charging to the absolute minimum, even if it seems convenient.
