How long do electric car batteries last?

Generally, electric car batteries last for as long as the rest of the car. But like with your phone or laptop battery, they degrade over time. Ultimately the cells should still be providing at least 70 percent of their capacity even after 200,000 miles, which is the sort of mileage that few cars ever reach, whether they’re ICE or EV.

How long does a car battery last after the warranty expires?

Even after the warranty expires, the battery can continue to function for many years. Although it may lose some capacity, it can still power the vehicle for a substantial distance. While new electric vehicle batteries are made to last a long time, there will be a point when you need to replace the battery.

Will a battery replacement keep you from going electric?

For many EV-curious buyers, the fear of spending thousands on a battery replacement at some point could understandably keep them from going electric. But a study done in March by Recurrent, a Seattle-based company that analyzes used electric car batteries, shows this is much less likely to happen than you might think.

How often do EV batteries degrade?

These findings challenge earlier concerns about rapid battery degradation in electric vehicles. On average EV batteries degrade 2.3% per year, but as newer models are released with better technology, that number has since improved to 1.8% per year. These figures highlight the remarkable advancements in battery technology.

Why do EV batteries last longer?

New battery technology, including better thermal management and advanced Battery Management Systems, helps batteries last longer. Though some wear is expected, things like charging habits and driving conditions affect how fast a battery loses its capacity. Real-life data shows that modern EVs have slow degradation rates.

When should EV batteries be replaced?

New Research Suggests It's Way Longer Than You Might Think An independent analysis of 15,000 EV batteries finds that most don't need to be replaced until they're well over a decade old. For many EV-curious buyers, the fear of spending thousands on a battery replacement at some point could understandably keep them from going electric.
