What to check when buying a used MG5
- Check whether the car was registered as a private-hire vehicle with MG – the general warranty is shorter for those cars. (MG 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)
How to check the battery on a used MG5
- Ask for the SoH on the MG service record and confirm with an independent test. (MGEVs.com owner forum)
- Ask for an independent battery test. AVILOO lists FLASH-test support for the MG5 Electric SR 50.3 kWh and LR 61.1 kWh packs shown above, so a dealer certificate or a mobile tester can give an SoH figure you can compare with the results on this page. (AVILOO GmbH)
Battery warranty (UK)
MG UK (warranty statement, online version dated 1 Jan 2025): vehicle 7 years / 80,000 miles; HV battery listed at 96 months / 100,000 miles with capacity below 70% treated as excessive loss. Private-hire/taxi registered EVs: vehicle 3 years / 60,000 miles (80,000 miles if registered from 22 Mar 2024), HV battery 8 years / 100,000 miles from 1 Jan 2025 – check how the car was registered.

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.
