Used Tesla Model 3 battery health & degradation data
Last updated: · 12 sourced data points
The Model 3 was the UK's best-selling used EV in 2025 (nearly 10% of used EV sales). Battery chemistry and cell supplier vary by version and year, and Swedish data shows this matters as much as mileage. Sources: Electrifying.com, Carla AB.
Battery options: Standard Range / RWD (LFP or NCA/NCM depending on year & factory), Long Range, Performance.

Data gaps: Most independent data is from Swedish dealers and the global AVILOO dataset; there is little published UK-only Model 3 data. Tesla's own figure (85% after 200,000 miles) covers Long Range packs only.
What to check when buying a used Model 3
- Find out the exact pack (LFP vs nickel-based, LG vs Panasonic cells). In Carla's data LFP Model 3s averaged 93.3% SoH after >100,000 km vs 88.2–89.8% for Panasonic packs. (Carla AB)
- Riddermarks: only 62.1% of Panasonic 77.8 kWh Model 3s were above 90% SoH (average 115,340 km), vs 97.6% of LG 78.8 kWh cars. (Ny Teknik / Riddermarks Bil)
- Ask the seller to show the warranty status in the Tesla app (Specs & Warranty) – remaining warranty is valuable. (Tesla 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)
Battery warranty (UK)
Tesla UK (current terms): Model 3 RWD – 8 years or 100,000 miles; Model 3 Long Range / Performance – 8 years or 120,000 miles; minimum 70% battery capacity retention over the warranty period.

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.
