Quick answer

A used Ford Mustang Mach-E (2021-present) typically has usable ~68-72 kwh (standard range) or ~88-91 kwh (extended range), by year, a WLTP range of around 273-379 miles depending on battery and drivetrain when new, and a battery warranty of 8 years / 100,000 miles to 70% capacity. The value of any individual car comes down to its battery health, check the real-world range now versus when new before you buy.

Ford Mustang Mach-E at a glance

Body type	Large SUV
Years	2021-present
Battery (usable)	Usable ~68-72 kWh (Standard Range) or ~88-91 kWh (Extended Range), by year
WLTP range (new)	Around 273-379 miles depending on battery and drivetrain
Real-world range	Roughly 225-295 miles in real use depending on battery, less in winter
Battery warranty	8 years / 100,000 miles to 70% capacity
Battery cooling	Active liquid cooling (no heat pump on UK cars)

Figures are typical across the model's life and vary by year and trim, treat them as a guide, not a guarantee for a specific car.

How the Mustang Mach-E's battery ages

Battery cooling is a big part of the story: this car uses active liquid cooling (no heat pump on uk cars). 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 Mustang Mach-Es on the same mileage can be worth different amounts.

What to watch out for on a used Ford Mustang Mach-E

Confirm the high-voltage contactor recall (and its 2025 re-fix) is done: it caused power loss on 2020-2022 cars
Early cars had a 12V charging fault that led to a UK door-lock recall covering almost the whole range, check completion
Battery capacity changed by year (68 to 70 kWh SR, 88 to 91 kWh ER, LFP on late Select cars), so confirm the exact car
Pre-facelift cars rapid-charge slower in practice (around 107 kW) than the brochure 150 kW suggests

What the Used EV Check shows for a Ford Mustang Mach-E

Enter the registration and the Used EV Check returns, for that specific Mustang Mach-E: 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 Ford Mustang Mach-E 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 Ford Mustang Mach-E FAQ

How do I check a used Ford Mustang Mach-E'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 Ford Mustang Mach-E'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 Ford Mustang Mach-E?+

Too new for long-term UK degradation figures, but the signs are good: the Mach-E topped What Car’s reliability survey for its class with no battery-degradation pattern reported. The battery-related risk on used cars is a specific recall rather than fade, so recall completion is the thing to confirm. 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 Mustang Mach-E 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 Ford Mustang Mach-E have?+

Ford Mustang Mach-E battery warranty is typically 8 years / 100,000 miles to 70% capacity. 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 Ford Mustang Mach-E?+

Around 273-379 miles depending on battery and drivetrain is the WLTP figure when new. In real use expect roughly 225-295 miles in real use depending on battery, less in winter, 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.

What is the Ford Mustang Mach-E battery contactor recall?+

On cars built between 2020 and 2022, the high-voltage battery main contactors could overheat and cut drive power. Ford’s fix was a control-module software update, and a smaller 2025 follow-up recall covered cars where the first fix had not installed correctly. It is a hardware and software issue rather than battery wear, so it does not mean the pack is unhealthy, but you should confirm both recalls have been completed on the specific car by registration.
