What to check when buying a used Xpeng
- G6 battery sizes changed between model years – check the exact pack on the V5C / spec sheet. (EV Database, AVILOO GmbH)
- 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 Xpeng
- Ask for an independent battery test. AVILOO lists FLASH-test support for the Xpeng G6 (66, 80.8, 87.5 kWh) and P7 86.2 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)
XPENG UK (G6 warranty leaflet): battery eight years or 100,000 miles, whichever comes first. The leaflet does not state the capacity threshold – ask XPENG what SoH level triggers a claim. Source: XPENG UK, checked 2026-10-20. Always confirm the terms for the specific car with the manufacturer.

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.
