Model S battery degradation — what to expect

~91%

Fleet average at 100,000 mi

Real-world fleet data across thousands of Model S vehicles shows remarkably consistent retention — one of the best long-term EV battery track records.

~88%

Fleet average at 200,000 mi

The degradation curve flattens significantly after the first 50,000 miles. Many high-mileage Model S owners report no meaningful impact on daily driving.

8 yr / 150k mi

Warranty period (all trims)

All Model S variants: 8 years or 150,000 miles, minimum 70% capacity retention.

The Model S has one of the best long-term battery track records of any EV. Early 18650-cell vehicles (2013–2016) showed slightly higher initial drops, but the curve flattens quickly. Newer 2170-cell variants (Long Range, Plaid) maintain capacity even more consistently. High-mileage Model S vehicles — 200,000+ miles — remain common and functional.

Charging tip

Set your daily charge limit to 80–90%. Supercharger use is fine for travel but heavy reliance on DC fast charging accelerates degradation over time.

Cell chemistry determines how you should charge. LFP owners can charge to 100% daily; NMC owners should stay at 80–90% for daily use.

Cell format

Model S: 18650 (2013–~2020), 2170 (newer variants). Battery capacity ranges from 62–98 kWh depending on trim and model year.

Model S battery health FAQs

How well does the Tesla Model S battery hold up long-term?
Among the best of any EV: fleet data shows about 91% capacity at 100,000 miles and still roughly 88% at 200,000 miles. Cars past 200,000 miles remain common and usable thanks to a curve that flattens early.
Do older 18650-cell Model S batteries degrade faster?
Early cars (2013–2016) showed a slightly larger initial drop, but the curve flattens quickly. Newer 2170-cell Long Range and Plaid packs hold capacity even more steadily over high mileage.
What is the battery capacity of a Model S?
Usable capacity ranges from about 62 kWh (60/60D) to 98 kWh (Long Range Plus), with most 100D and Plaid cars around 95 kWh. The table above breaks it down by variant and year.
Is the Model S battery under warranty?
Yes — 8 years or 150,000 miles, with a minimum 70% capacity retention guarantee across all trims.
