Hyundai Kona Electric Battery FAQ

How long does the Hyundai Kona Electric battery last?

Based on aggregated real-world data, the Hyundai Kona Electric loses roughly 1.8% of its capacity per year. At 100,000 km it typically retains about 91.9% State of Health, and it is covered by a 10-year / 160,000 km battery warranty down to 70% capacity. Most Kona Electric batteries are expected to outlast the rest of the car.

How much does it cost to replace a Hyundai Kona Electric battery?

A full Hyundai Kona Electric pack is around 64 kWh. At current installed prices of roughly $120–$180 per kWh, an out-of-warranty replacement would land in the $7,700–$11,500 range — but module-level repair is often far cheaper, and most owners never need it. See our EV battery replacement cost guide.

Is a used Hyundai Kona Electric a good buy?

A used Hyundai Kona Electric can be an excellent value as long as the battery is healthy. Always check the State of Health before buying — at 88% (typical at higher mileage) the car still delivers strong daily range. Run a free VoltChek estimate and confirm with an OBD2 scanner before you commit.
