The Jeep EV battery warranty
Jeep battery cover is typically 8 years / 100,000 miles to 70% capacity, with an optional 3-year extension. The warranty usually transfers with the car, so what matters on a used one is how much is left and whether the battery is still comfortably above the capacity threshold. Read more in our guide to how EV battery warranties work.
How Jeep EV batteries age
Jeep’s first mainstream EV, the Avenger, uses a Stellantis liquid-cooled battery of around 51 kWh usable with a sensible capacity buffer, so it should age steadily, but the car has only been on sale since 2023, so there is little long-term data yet. The bigger used-buyer traps are not the battery: making sure you are looking at the electric Avenger rather than the petrol or mild-hybrid versions, and checking the 2024 recalls and the patchy electronics.
Whatever the make's reputation, individual cars vary with charging habits, climate and mileage, which is why we always frame battery health as an estimate for the specific vehicle. Our guide to what's normal for EV battery degradation covers the general picture.

What the Used EV Check shows for a Jeep
Enter the registration and the Used EV Check returns, for that specific car: 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, plus the full MOT and mileage history.
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.
