According to the U.S. Department of Energy’s National Renewable Energy Laboratory, modern EV batteries will last anywhere from 12 to 15 years in moderate climates and operate between 100,000 and 200,000 miles—and even longer with careful charging practices. Hydrogen tanks in fuel cell electric vehicles generally have a certified lifespan of about 15 years.
For comparison, the Bureau of Transportation Statistics reports that the average age of all passenger vehicles in the U.S. is 12-13 years, meaning EVs and hydrogen fuel cell electric vehicles can match or exceed the typical lifespan of conventional cars.
If you are still concerned, know that most of these vehicles come with battery warranties of 8 years or 100,000 miles (some brands offer up to 10 years or higher mileage). These warranties typically guarantee that the battery will retain around 70% of its original capacity during that period. In addition to the battery, EVs also include standard bumper-to-bumper and powertrain warranties, so drivers can expect reliability for many years—often well beyond the warranty period.
