In short: Tesla’s fleet data shows Model 3 and Model Y batteries losing about 15% of capacity on average after 200,000 miles. Independent fleet data puts typical EV battery fade at around 2% a year, faster with heavy DC fast charging, and battery replacements outside recalls are rare.
An earlier version of this page included owner quotes and study figures we could not trace to a source. They are gone. Every number below comes from a named, published source listed at the end.
What the large data sets show
| Source | Sample | Finding |
|---|---|---|
| Tesla 2023 Impact Report | Tesla’s own fleet | Model 3/Y: about 15% average capacity loss after 200,000 miles. Model S/X: about 12%. |
| Geotab, January 2026 | 22,700+ EVs, 21 makes and models | Average fade 2.3% a year (1.8% in its 2024 study). Heavy DC fast charging above 100 kW: up to 3.0% a year; mostly AC: about 1.5%. |
| Recurrent, November 2025 | US EVs on its platform | Under 4% of EVs had a battery replaced outside major recalls, including 10-year-old cars; about 0.3% for 2022 and newer models. |
Batteries do not fade in a straight line. Recurrent describes an S-shaped curve: a small early drop, then a long, slow decline. As a rough illustration only, Geotab’s 2.3% average over eight years would leave a pack near 82% of new, well above Tesla’s 70% warranty threshold.
Myth: Supercharging destroys the battery
Charging power is now the biggest factor Geotab found, ahead of climate. Vehicles that depend heavily on DC fast charging above 100 kW faded up to 3.0% a year, about twice the roughly 1.5% of vehicles charged mostly on AC. That is a real difference for a ride-hail car that Supercharges daily, and a small one for a typical owner who charges at home and Supercharges on trips.
Myth: never charge to 100%
Geotab found degradation only rose noticeably when vehicles spent more than 80% of their time near full or near empty. The practical advice depends on chemistry:
- LFP packs (some rear-wheel-drive trims, including Canada’s Model 3 Premium RWD): Tesla’s owner’s manual recommends keeping the charge limit at 100%, even for daily use, and fully charging at least once a week.
- Nickel-based packs (Long Range and Performance): use the lower daily limit Tesla suggests and charge to 100% shortly before a long drive.
Not sure which you have? On LFP cars the charge-limit slider is labelled 50% and 100%; on nickel-based cars it says Daily and Trip.
Myth: cold winters wear out the battery
Cold cuts range temporarily, often by a quarter or more in Canadian winter tests (see our winter range guide), but the range returns when it warms up. For long-term wear, Geotab found the opposite climate effect: vehicles in hot regions faded about 0.4 percentage points a year faster than those in mild ones.
Myth: you will need a new battery in five years
Recurrent’s November 2025 data found replacement rates of about 8.5% for first-generation EVs (2016 and older), about 2% for second-generation EVs including early Model 3s, and about 0.3% for 2022 and newer models. Many of the replacements that did happen were covered by warranty.
What Tesla’s battery warranty covers
New Teslas carry an 8-year battery and drive unit warranty with a distance limit that depends on the model and trim, and Tesla guarantees at least 70% of original capacity during that period. Rear-wheel-drive Model 3 and Model Y trims have historically had the lowest distance limit, and Drive Tesla Canada reported in 2026 that the Canadian Model 3 Premium RWD moved to 8 years or 160,000 km. Confirm the terms for your exact car on Tesla’s warranty page before you buy.
How to slow battery wear
- Charge at home on AC when you can, and treat Superchargers as the road-trip tool they are.
- Follow the charge-limit advice for your chemistry, and avoid leaving a nickel-based pack at 100% or near empty for days.
- Park in shade or a garage in hot weather; heat is the climate factor that showed up in long-term wear.
- If you are shopping used, check battery health and remaining warranty first. Our used Tesla guide covers how.

Frequently asked questions
How much battery capacity does a Tesla lose?
Tesla’s 2023 Impact Report put the average loss at about 15% after 200,000 miles (about 320,000 km) for Model 3 and Model Y, and about 12% for Model S and Model X. Individual cars vary.
Does Supercharging wear out the battery faster?
Somewhat, if it is most of your charging. Geotab’s January 2026 study of more than 22,700 EVs found vehicles relying heavily on DC fast charging above 100 kW lost up to 3.0% a year, about double the roughly 1.5% for vehicles mostly charged on AC. Occasional road-trip Supercharging makes little difference.
What does the Tesla battery warranty cover?
Tesla covers the battery for 8 years with a mileage limit that depends on the model, and guarantees at least 70% capacity within that period. Check the exact distance for your car on Tesla’s warranty page; Drive Tesla Canada reported that the Canadian Model 3 Premium RWD moved to 160,000 km in 2026.
How often do Tesla batteries need replacing?
Rarely. Recurrent’s November 2025 analysis found under 4% of EVs had a battery replaced outside of major recalls, about 2% for second-generation EVs such as early Model 3s and about 0.3% for 2022 and newer models.
Should I charge my Tesla to 100%?
It depends on the battery. For LFP batteries Tesla recommends keeping the limit at 100% and fully charging at least weekly. For nickel-based packs (Long Range and Performance), Tesla’s guidance is a lower daily limit and 100% only before a long trip.
