What to check when buying a used Zoe
- Check whether the battery is owned or leased – a leased battery means ongoing monthly payments and separate terms. (Renault UK)
- Riddermarks: only 61.3% of Zoe 40 kWh cars tested were above 90% SoH (average 79,336 km). (Ny Teknik / Riddermarks Bil)
- 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)

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.
