The Lexus EV battery warranty
Lexus battery cover is typically 8 years / 100,000 miles to 70% capacity, extendable to 10 years / 1,000,000 km with annual Lexus battery health checks, alongside the service-activated Lexus Relax vehicle warranty. 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 Lexus EV batteries age
Lexus backs its EV batteries harder than almost anyone: the UX 300e’s pack is warranted to 70% for up to 10 years and 1,000,000 km where the annual health check is done, and the Relax programme keeps the vehicle warranty rolling for up to 10 years as long as it is serviced at Lexus. The pack is air-cooled and charges gently, but it uses the older CHAdeMO rapid-charge standard, which is worth weighing for longer trips.
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 Lexus
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.
