How long do EV batteries last?

Modern EVs are designed to last 15-20 years, comparable to or even longer than traditional internal combustion engine (ICE) vehicles. The key factor in their longevity is the battery. EV batteries are typically considered at the end of their life when they drop below 70 to 80 per cent of their original capacity.

How long do EV battery warranties last?

However, most EV battery warranties come with an important caveat; the maximum charge capacity of the battery can fall to a certain percentage in those eight years, without it being considered broken. This is usually pegged at 70 percent.

Will EV batteries outlast the life of a car?

Data published in September 2024 by Geotab, a transportation telematics company, claims the “vast majority of EV batteries will outlast the usable life of the vehicle”. The company says how, with a sample size of 5,000 EVs representing 1.5 million days of ownership, the average battery degrades by 1.8 per cent per year.

How long does a car battery last?

The degradation curve also begins shallowing out, indicating a loss of around 10 percent capacity or less after 150,000 or even 200,000 miles. On our long-term Model 3, the battery degraded roughly 6 percent in the first 20,000 miles, but then held there all the way to our 40,000-mile end point.

How much battery capacity does an EV lose a year?

Indeed, EVs are currently estimated to lose an average of 2.3% of their battery capacity per year. To put that into context, if you purchase an EV today with a 240 km (150 miles) range, you’ll have only lost about 27 km (17 miles) of accessible range after five years.

Are EV batteries worth it?

Battery replacement is the most significant expense associated with owning an EV. While early EV models showed faster battery degradation, contemporary batteries, with improved technology and management systems, are now much more durable than before.
