Buying an electric vehicle is a major purchase, so naturally you’ll want to be confident that your new wheels will last you for the long run. This is why the battery life of electric cars is an important question for many new buyers. We’re all familiar with how smartphone batteries seem to run out of juice much faster after a couple of years use, so you don’t want to experience the same thing with your car.
As a general rule, an EV battery is said to be degraded once it can no longer reach 80% of its original charge – at this point it won’t give you the range or reliability you need.
The good news is that electric car battery life expectancy is actually pretty long. Most manufacturers today say you can expect the batteries to last at least eight years or 100,000 miles before reaching that 80% threshold. That’s about the same distance as in a traditional car before things start going wrong. According to a study by GeoTab, a firm that tracks thousands of EV’s performance, the battery life of an electric car will decrease by a fairly negligible 2.3% per year.
So, how long do EV batteries last, what makes them degrade, and what protections are in place? Read our guide on electric car battery life expectancy to find out.
