You’re tempted by this used electric car. What is its battery really worth?
A listing, a year, a mileage. And alongside them, the answers no other site brings together: how long the manufacturer covers the battery, what condition it is likely to be in, whether it is leased, and what a failure would cost.
What is this car’s battery worth?
Remaining warranty, expected state of health, battery lease and cost of a failure. All at once — and nothing you enter leaves your browser.
We check, we don’t certify. The date of first registration is shown in box B of the V5C logbook. The state of health given is a range calculated from the battery’s age, mileage and chemistry: only a measurement on the vehicle gives a figure.
Duration, mileage and capacity threshold, by model and by range of years, with their sources. When sources disagree on a condition, we don’t publish it.
Nobody knows a battery’s state of health without measuring it. We estimate where a comparable battery sits – only a measurement on the car gives the exact figure.
No certificate, no measurement, no car for sale. When the useful answer earns us nothing – a battery still under warranty is repaired free of charge by the manufacturer – that is the answer we give.
