Nearly every EV sold today carries at least an 8-year / 100,000-mile battery warranty, usually promising the pack won't fall below about 70% of capacity in that window. Hyundai and Kia lead on duration, offering 10 years / 100,000 miles on many models. Tesla and Rivian stretch the mileage limit, with some packs covered to 150,000-175,000 miles. Mainstream brands — Ford, GM, VW, Nissan, BMW, Mercedes, Volvo, Polestar — mostly cluster at the 8-year / 100,000-mile, 70% baseline. The capacity floor matters as much as the years: it defines when a faded battery actually qualifies for a free repair.
EV battery warranties by brand (US, 2026)
| Brand | Years | Mileage | Capacity floor |
|---|---|---|---|
| Hyundai / Kia | 10 years | 100,000 miles | ~70% |
| Tesla | 8 years | 100,000-150,000 miles | 70% |
| Rivian | 8 years | up to 175,000 miles | 70% |
| Ford / GM | 8 years | 100,000 miles | ~70% |
| VW / Nissan / BMW / Mercedes | 8 years | 100,000 miles | ~70% |
How EV battery warranties work
An EV battery warranty is separate from the car's bumper-to-bumper cover and is the most valuable single guarantee on the vehicle. It has two parts that both matter. The first is the time-and-mileage limit — whichever comes first. The second, often overlooked, is the capacity threshold: the percentage of original capacity below which the maker will repair or replace the pack. A battery can fade and still be 'within warranty' on years and miles, yet only qualify for a free fix if it drops under that floor, typically 70%.
In the US, regulations require at least 8 years / 100,000 miles of emissions-related coverage that includes the battery, which is why so many brands converge on that number. California-emissions states have historically pushed for longer terms on some components.
Who offers the best coverage
Longest duration: Hyundai and Kia
Both Korean brands build long warranties into their identity. Many Hyundai and Kia EVs carry 10 years / 100,000 miles of battery cover with a roughly 70% capacity guarantee — two extra years over the industry baseline. Note that some terms differ for second owners, so the full 10 years may apply only to the original buyer in certain markets.
Highest mileage: Tesla and Rivian
Tesla covers most batteries for 8 years, with the mileage limit rising by model: shorter-range cars sit nearer 100,000 miles while long-range Model S and X packs reach 150,000 miles, all to a 70% floor. Rivian keeps the 8-year limit but stretches mileage furthest, with some large-pack R1T and R1S configurations covered up to 175,000 miles — attractive for high-mileage drivers.
The mainstream baseline
Ford, GM, Volkswagen, Nissan, BMW, Mercedes-Benz, Volvo and Polestar mostly land on the same formula: 8 years / 100,000 miles with a roughly 70% capacity guarantee. The differences between them are usually in the fine print — proration, transferability and how aggressively each defines a qualifying fault — rather than the headline numbers.
The fine print that catches people out
- Capacity floor vs years: a pack that fades to 75% at year five is 'in warranty' but won't be replaced free, because it hasn't dropped below 70%.
- Whichever comes first: high-mileage drivers hit the mileage cap years early; low-mileage owners are limited by the years.
- Transferability: most US battery warranties transfer to later owners, but some perks (and longer Hyundai/Kia terms) may not — check before buying used.
- What counts as a fault: normal gradual degradation above the floor is excluded; warranties cover defects and capacity dropping below the threshold, not everyday fade.
- Service conditions: skipping required software updates or using non-approved repairs can affect a claim.
Ask three questions: how many years and miles, what is the capacity floor (almost always ~70%), and does the cover transfer to you as a second owner. Those three answers tell you almost everything about what the battery guarantee is really worth.
How often are batteries actually replaced?
Rarely. Independent data suggests only a low single-digit percentage of EVs ever need a battery replacement, and most that do are covered by warranty or recall. Because average degradation runs near 2.3% a year, the typical pack stays comfortably above the 70% threshold for the full warranty period and well beyond. The warranty is real protection, but for most owners it is insurance against an unlikely event rather than a scheduled cost.
UK and India in brief
The 8-year / 100,000-mile (or 160,000 km) battery warranty is broadly the global norm. In the UK, terms are usually quoted in miles or kilometres with the same ~70% capacity language, and Hyundai/Kia again lead on duration. In India, several manufacturers offer 8-year battery cover, and some have promoted longer or lifetime-style warranties on specific models — always confirm the exact years, kilometres, capacity floor and transfer terms in the local owner's handbook, as they differ from US figures.
