MG5 EV Battery Health & Range: Used Buyer’s Guide

Quick answer

A used MG5 EV (2020-2025) typically has usable ~46-49 kwh standard range (lfp on the facelift) or ~57.4 kwh (61.1) long range, a WLTP range of around 199-250 miles depending on battery when new, and a battery warranty of 7 years / 80,000 miles on cars registered before 2024, 8 years / 100,000 miles from 2024, 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.

MG5 EV at a glance

Body type	Estate
Years	2020-2025
Battery (usable)	Usable ~46-49 kWh Standard Range (LFP on the facelift) or ~57.4 kWh (61.1) Long Range
WLTP range (new)	Around 199-250 miles depending on battery
Real-world range	Roughly 150-210 miles in real use depending on battery
Battery warranty	7 years / 80,000 miles on cars registered before 2024, 8 years / 100,000 miles from 2024, to 70% capacity
Battery cooling	Active liquid cooling

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 MG5's battery ages

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 MG5s on the same mileage can be worth different amounts.

What to watch out for on a used MG5 EV

A pre-facelift Long Range charges much more slowly than the facelift car (about 63 kW vs 87 kW on DC, 6.6 kW vs 11 kW on AC), confirm which you’re viewing
Chemistry differs: the Standard Range is generally LFP and the Long Range NMC, which changes ideal charging habits
An early-car recall covered brake lights not showing under strong regenerative braking, check it was done
Pre-facelift (2020-2022) interiors feel built to a price, and the MG5 has no Euro NCAP crash rating

What the Used EV Check shows for a MG5 EV

Enter the registration and the Used EV Check returns, for that specific MG5: 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 MG5 EV 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 MG5 EV FAQ

How do I check a used MG5 EV'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 MG5 EV'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 MG5 EV?+

The UK’s only mainstream used electric estate, and the liquid-cooled packs have aged well in owner data: one high-mileage Long Range still held around 86% after 103,000 miles, and a Standard Range taxi around 99% after 45,000 miles. The facelift Standard Range uses an LFP battery that is happy being charged to 100% daily. 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 MG5 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 MG5 EV have?+

MG5 EV battery warranty is typically 7 years / 80,000 miles on cars registered before 2024, 8 years / 100,000 miles from 2024, 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 MG5 EV?+

Around 199-250 miles depending on battery is the WLTP figure when new. In real use expect roughly 150-210 miles in real use depending on battery, 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.

Does the pre-facelift MG5 EV charge slowly?+

Noticeably, yes. The original 2020-2022 MG5 EV tops out at around 63 kW on a DC rapid charger and 6.6 kW on AC, so a rapid charge takes longer than most rivals and a home charge is slower too. The 2022 facelift raised this to about 87 kW DC and 11 kW AC. If you do regular longer trips, the facelift car is worth seeking out, and either way check the specific car’s charging speeds rather than assuming.
