What to check when buying a used Kona Electric
- Check recall and software-update history with a Hyundai dealer (Hyundai says changes from battery-protecting software updates are not covered by the warranty). (Hyundai Motor UK)
- Ask whether it was used as a taxi/private hire – that shortens the battery warranty to 5 years / 100,000 miles. (Hyundai Motor UK)
- Compare any test result with the ranges above and with the ADAC rule of thumb: at least 92% at 50,000 km, 88% at 100,000 km, 84% at 150,000 km, 80% at 200,000 km. (ADAC)
Battery warranty (UK)
Hyundai UK: high-voltage battery warranty of 8 years or 100,000 miles for Kona EV 20MY and all newer production models (8 years or 125,000 miles for models first produced before 2020); 5 years / 100,000 miles for taxi, private hire or driving-school use.

Model averages can't tell you about the car in front of you. An independent battery test (typically a short OBD plug-in test, some remote) gives an SoH figure and often a certificate you can use when negotiating.
- AVILOO – Independent OBD-based battery test (FLASH / Premium) with certificate; available via partners in the UK and EU.
- Generational – UK remote battery health assessment and certificate, used by dealers and fleets.
