Battery state of health is the new odometer
Why a 40,000-mile EV at 98% is a better buy than a 20,000-mile one at 89%.
Mileage tells you how far a gas car has been driven. It tells you almost nothing about how much life is left in an EV's battery, which is why state-of-health (SoH) numbers matter more than the odometer once you're shopping electric.
A 40,000-mile EV reporting 98% SoH has a healthier battery — and a longer remaining range — than a 20,000-mile EV sitting at 89%, because SoH tracks charging habits and climate exposure, not just distance. Ask for the SoH reading from the car's own diagnostics before you commit, not a generic range estimate from the listing.
