The battery is the single biggest factor in an electric car’s value and usable range — and the one thing you can’t judge by looking. We read it for you using professional Bosch diagnostic equipment, then explain plainly what the figure means. No jargon, no sales pressure.
EV Battery Health Check — £67.50
A direct read of your vehicle’s State of Health (SoH) through the diagnostic port, using our Bosch KTS 590 and ESItronic software — the same platform main dealers use. You’ll get the SoH percentage, a clear explanation of what it means for your range, and the diagnostic printout to keep. Ideal for peace of mind, or before a private sale or purchase.
EV Battery Health Certificate — £95
Everything in the check, presented as a branded AZ Autos certificate you can show a buyer or keep on file. Includes the SoH figure with a Good / Fair / Degraded rating, estimated real-world range across summer, mixed and winter driving, remaining manufacturer battery warranty, and full vehicle details — handed over with a face-to-face explanation.
What the figure means — and what it doesn’t
State of Health is read directly from your vehicle’s own battery management system. It’s a point-in-time snapshot of the capacity the battery reports — not an independent laboratory measurement, and not a guarantee of future performance. We’ll always talk you through it honestly.
Vehicle compatibility
Battery health data is available on most, but not all, electric vehicles depending on make, model and how the manufacturer shares it. We confirm your car is supported before your appointment, so you’re never charged for a check we can’t complete.
