Tesla Model S Battery Health & Range, Used Buyer’s Guide

Thinking of buying a used Tesla Model S? Here's the battery, range and warranty picture, and the checks that tell you whether a particular car is a good one before you go and see it.

Published 4 July 2026 · EV All Day

Quick answer

A used Tesla Model S (2014-present (UK)) typically has usable ~70-100 kwh across the 70/75/85/90/100 packs, a WLTP range of around 240-405 miles depending on pack and age when new, and a battery warranty of 8 years / 150,000 miles on later cars; 8 years / unlimited miles on some older ones. The value of any individual car comes down to its battery health, check the real-world range now versus when new before you buy.

How the Model S's battery ages

Model S packs are famous for longevity, often past 90% capacity after very high mileage. But you’re usually buying an older, higher-value car, so verify the actual capacity now rather than trusting the reputation.

Battery cooling is a big part of the story: this car uses active liquid cooling. Cars that have spent their life on rapid chargers, been left sitting at 100%, or lived somewhere hot tend to lose capacity faster, which is why two identical Model Ss on the same mileage can be worth different amounts.

What to watch out for on a used Tesla Model S

  • Older cars, check the range shown at 100% against the original and any battery/BMS history
  • Free Supercharging and some features are car-specific and may not transfer to you
  • Air suspension, door handles and the MCU (main screen) are known wear items
  • Confirm which Autopilot/hardware generation the car has

What the Used EV Check shows for a Tesla Model S

Enter the registration and the Used EV Check returns, for that specific Model S: its expected real-world range now versus when new, an estimated degradation figure, a battery-health grade where a manufacturer test record exists, and the battery warranty remaining in miles and months. It also pulls the full MOT and mileage history so you can spot clocking or a car that has covered far more motorway miles than the advert suggests.

It's the fastest way to tell a good Tesla Model S from a tired one before you drive out to view it. For the wider process, see our complete used-EV buyer's guide and how to check an EV's battery health.

Range and battery-health figures are estimates modelled from real-world data and are shown for the specific vehicle in the Used EV Check. Range data is powered by ClearWatt. A battery-health grade is shown where a manufacturer test record exists, it is a comparative grade, not a measured state-of-health percentage.

Used Tesla Model S FAQ

How do I check a used Tesla Model S's battery health?+
You can't see battery state of health on the V5C, the MOT or the advert, and DVLA doesn't publish it. Enter the registration into the Used EV Check and it returns this Tesla Model S's estimated real-world range now versus when new, its degradation estimate, a battery-health grade where a manufacturer test record exists, and the remaining battery warranty. Range data is powered by ClearWatt.
How much battery degradation is normal on a used Tesla Model S?+
Model S packs are famous for longevity, often past 90% capacity after very high mileage. But you’re usually buying an older, higher-value car, so verify the actual capacity now rather than trusting the reputation. As a rule of thumb, most EV batteries lose the first few percent early on and then settle to a slow decline, so a used Model S that still returns close to its original range for its age and mileage is a good sign. The Used EV Check estimates this specific car's degradation for you.
What battery warranty does the Tesla Model S have?+
Tesla Model S battery warranty is typically 8 years / 150,000 miles on later cars; 8 years / unlimited miles on some older ones. It covers the battery falling below a set capacity within that time or mileage, and it usually transfers to you as the next owner. The Used EV Check shows how much of the warranty is left in miles and months.
What is the real-world range of a used Tesla Model S?+
Around 240-405 miles depending on pack and age is the WLTP figure when new. In real use expect roughly 180-330 miles in real use, and less again in cold weather or at motorway speeds. What matters on a used car is the expected range now, which the Used EV Check estimates for the specific vehicle rather than quoting the brochure.
