How long do EV batteries last?

The short answer: longer than most people fear. Batteries do lose some capacity every year, so a car's range slowly drops, but for most modern EVs the loss is gradual and a full replacement is rare. Geotab concludes that modern EV batteries are built to last beyond a typical vehicle's service life, and Recurrent reaches a similar view from its own data.

What the real-world data shows

Average wear is about 2% a year. Geotab, a fleet telematics company, analyzed more than 22,700 electric vehicles across 21 models. The average loss of battery capacity was 2.3% per year. If that rate held steady, a car would still have roughly 80% of its original capacity after eight years. Its earlier analysis found 1.8% a year, so the figure moves a little between studies and models.

Replacements are uncommon. Recurrent, which tracks battery health in more than 30,000 EVs, reported in late 2025 that:

• under 4% of the cars it tracks have had a battery replaced outside of major recalls, including cars more than 10 years old;
• about 8.5% of first-generation EVs have had one;
• about 2% of second-generation models, such as early Chevy Bolt EVs and Tesla Model 3s;
• only 0.3% of 2022 and newer models.

Lifespan estimates. The US government's FuelEconomy.gov site cites a Department of Energy study suggesting EV batteries may last 12 to 15 years in moderate climates. AAA says most last eight to 15 years, depending on climate, driving and charging habits.

Wear is not perfectly steady over a battery's life; Recurrent describes it as an S-shaped curve rather than a straight line. And the range shown on the dashboard is not a perfect measure of battery health, because software updates and the weather both change it.

What makes a battery wear faster

Geotab's data points to three main factors:

Cars in hot climates also lost about 0.4% a year more than those in mild climates.

None of this means you should avoid fast charging on a road trip. It means the battery lasts longest when most of your charging is slower AC charging, at home or at work.

What the warranty covers

The standard battery warranty in the US is 8 years or 100,000 miles160,000 km, whichever comes first, according to Recurrent and AAA. Some carmakers go further: Recurrent notes that Hyundai EV batteries from 2020 onward are covered for 10 years or 100,000 miles160,000 km. Nissan covers new Leaf batteries for 8 years or 100,000 miles160,000 km.

Most warranties cover two things:

• Defects that stop the battery working.
• Excessive capacity loss. A common threshold is 70% of original capacity. For example, the Tesla Model 3 Standard Range is guaranteed to keep at least 70% for 8 years or 100,000 miles160,000 km. Thresholds and how they are measured differ by brand.

Warranties do not cover accident damage or damage from not following the maintenance instructions. Terms also vary by country and model year, so read the warranty booklet for your exact car.

If the battery does need work

Out of warranty, AAA estimates a full replacement at $5,000–$20,000≈ £3,900–£16,000≈ €4,500–€18,000≈ A$7,500–A$30,000 or more, depending on battery size and the car. Ask for a written diagnosis first: a fault is not always the whole battery.

How to help your battery last

• Do most of your charging on slower AC charging, and save fast charging for trips.
• Avoid leaving the car sitting at 100% or near empty for long periods. Your owner's manual says what daily charge limit it recommends.
• Park in the shade or a garage in hot weather when you can.
• Keep the car's software up to date and have it serviced as the manual says.
• Buying used? Ask for a battery health check and see how much warranty is left. Our used car checklist covers the rest.
