Tesla battery degradation data from 100,000+ mile owners. Model 3 and Model S long-term capacity retention covered. What to expect at 100k, 150k and 200k miles.
This High Mileage Guide guide combines structured analysis β verdicts, risk scoring and cost ranges where we have enough data β with real fault cases pulled directly from MyCarFault's reporting database, so the guidance below reflects what owners actually experience rather than manufacturer specifications alone. Background and analysis come first, followed by the linked fault reports and related guides you can jump to directly using the links above.
Tesla battery degradation is one of the most researched topics in EV ownership. Unlike combustion engines where high mileage creates progressive mechanical wear, Tesla battery degradation is relatively gradual and predictable β and significantly better than early fears suggested.
No β 100,000 miles typically shows 5-8% capacity loss. Barely perceptible in real-world range.
Marginally β sustained Supercharger-only use shows slightly higher degradation than mixed AC/DC. For most owners this is negligible.
Model 3 LFP (SR+, post-2021) shows best retention data. Model 3 Long Range also very strong.
