FAQ
How long is a used EV battery warranty?
For most of the 35 models we cover, the UK battery warranty runs 8 years from first registration with a mileage cap of around 100,000 miles, and applies if capacity falls below 70%. Exceptions include older Nissan Leafs (5 years / 60,000 miles, measured in capacity bars), Kia cars registered before 2024 (7 years), BYD (250,000 km), smart (125,000 miles) and Dacia Spring (75%).
Does the battery warranty transfer to a second owner?
Usually the cover belongs to the car, but check the wording: Vauxhall describes its battery warranty as transferable, while Tesla says it transfers when ownership is transferred through Tesla. Read the full terms on the model page and confirm with the manufacturer using the VIN.
Is normal battery degradation covered?
No. Battery warranties cover capacity falling below a set threshold (usually 70%) or defects within the time and mileage limits. Gradual loss above that threshold is treated as normal ageing.
Is my input stored?

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 OBD plug-in test with certificate (SoH, range, remaining warranty, cell balance); sold through dealers and independent mobile testers.
- Moba – Postal OBD kit: you run the test yourself and post the box back for a digital battery certificate (Europe – check vehicle support and delivery country).
