Quick answer

A used Hyundai Ioniq 5 (2021-present) typically has usable ~54 kwh (58) or ~70-74 kwh (72.6 then 77.4 from 2022); ~80 kwh (84) on the 2024 facelift, a WLTP range of around 249-354 miles depending on battery and year 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.

How the Ioniq 5'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 Ioniq 5s on the same mileage can be worth different amounts. Read more in our guide to what's normal for EV battery degradation.

What to watch out for on a used Hyundai Ioniq 5

The ICCU recall is the priority: confirm it was completed, and because some cars failed again after a software-only fix, check whether the unit was replaced
Four battery sizes over its life (58, 72.6, 77.4 and the 2024 facelift’s 84 kWh) on near-identical cars, confirm which by build date and spec
Pre-2024 cars have no rear wiper, a long-standing owner gripe fixed only at the facelift
The 800V rapid-charging headline needs a 350 kW-class charger, and heat-pump fitment varied on early trims

What the Used EV Check shows for a Hyundai Ioniq 5

Enter the registration and the Used EV Check returns, for that specific Ioniq 5: 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 Hyundai Ioniq 5 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 Hyundai Ioniq 5 FAQ

How do I check a used Hyundai Ioniq 5'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 Hyundai Ioniq 5'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 Hyundai Ioniq 5?+

Like its EV6 cousin, the Ioniq 5’s 800V E-GMP pack ages slowly, with US fleet data showing around 98% of range retained after five years. The real used-buyer issue is not degradation but the ICCU recall, so recall completion matters more here than battery-health fear. 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 Ioniq 5 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 Hyundai Ioniq 5 have?+

Hyundai Ioniq 5 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 Hyundai Ioniq 5?+

Around 249-354 miles depending on battery and year is the WLTP figure when new. In real use expect roughly 180-275 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.

Which Hyundai Ioniq 5 battery is which?+

There are four. The car launched in 2021 with a 58 kWh Standard Range and a 72.6 kWh Long Range; the Long Range grew to 77.4 kWh in spring 2022; and the 2024 facelift moved to 63 and 84 kWh packs. The cars look almost identical, so a 2021 72.6 kWh and a 2022 77.4 kWh are easy to mix up. Check the build date and spec, and use the battery capacity on a report rather than the badge, since the headline figure is the gross size, not the usable one.
