Data gaps: Large datasets group the 64/78 kWh cars; little independent data yet for the 2024-on 69/70/82 kWh packs (one single-car Moba certificate and one Polestar certificate).
What to check when buying a used Polestar 2
- Find out the battery supplier on a 78 kWh car: in Carla's data CATL-cell cars averaged 94.35% and LG Chem 93.53% after more than 100,000 km. (Carla AB)
- Riddermarks found 99.6% of 273 tested Polestar 2 78 kWh cars above 90% SoH (average 88,050 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)
How to check the battery on a used Polestar 2
- Polestar workshops can issue an official battery state-of-health certificate (cyclable capacity at 25°C vs nominal). (Polestar / Brandt Personbilar AB Skövde)
- Ask for an independent battery test. AVILOO lists FLASH-test support for the Polestar 2 64–82 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)
Polestar UK: battery 8 years or 100,000 miles, whichever comes first; if SoH drops below 70% of original capacity within the first 8 years the battery is repaired or replaced at no cost. Vehicle warranty 3 years / 60,000 miles. Source: Polestar UK, checked 2026-10-20. Always confirm the terms for the specific car with the manufacturer.

What is the Polestar 2 battery warranty in the UK?
Polestar UK: battery 8 years or 100,000 miles, whichever comes first; if SoH drops below 70% of original capacity within the first 8 years the battery is repaired or replaced at no cost. Vehicle warranty 3 years / 60,000 miles.
What battery chemistry does the Polestar 2 use?
NMC for all versions (64/78 kWh 2020–2023; 70/82 kWh 2024–2025).
How can I check the battery of a specific Polestar 2?
Use an independent battery test (OBD-based or remote) and compare the result with the ranges on this page. Model averages cannot tell you the condition of one specific car.
