EV Battery Health Testing in Gateshead, Tyne and Wear

Know Your EV's Real Battery Health in Gateshead
State of health is the industry way of describing an EV battery's condition — the percentage of its original usable capacity still available today, since every lithium-ion battery loses a little capacity over time through age, charge cycles and how often it's been fast-charged. It matters most when you're buying or selling a used EV, since two cars of the same age and mileage can have very different real-world range depending on how the previous owner treated the battery, and it matters if your own range has started to feel shorter than the dashboard suggests it should.
State of health is read straight from the battery's own management system, not guessed at from how the car feels to drive, which is what makes it worth doing for EV owners across Gateshead and Birtley who want a real answer. You'll get a plain-English explanation of what the percentage means for your range and, if you're buying or selling, a written result to back it up.

Frequently Asked Questions
What does 'state of health' actually mean for an EV battery?
It's the percentage of the battery's original usable capacity that's still available today, worked out from data held in the battery management system rather than anything you can judge just by driving the car. A battery reading close to its original figure is behaving close to new, while a lower figure means less range is available than the car had when it left the factory.
Is a lower state of health a fault, or is that just normal?
All lithium-ion batteries lose some capacity over time through age, charge cycles and how often the car has been fast-charged, so a modest drop after several years on the road is expected rather than a fault. What matters is whether the figure is in line with the car's age and mileage or noticeably worse than that, and that's exactly what the test tells you.
Can you test a used EV before I decide to buy it?
Yes — it's one of the most useful checks you can do on a used EV, since two cars of the same age and mileage can have very different battery health depending on how the previous owner charged and drove it. Bring the car in, or ask the seller if you can bring it to us, and we'll tell you honestly what the battery's actual condition is.
Do you carry out high-voltage work on the battery pack itself?
No — our test reads data from the battery management system without opening the high-voltage pack, which is enough to establish state of health accurately. If a result points to something that needs pack-level investigation or repair, we'll say so honestly rather than take on work outside what we do.
What do I actually get from an EV battery health test?
A clear state of health percentage, a plain-English explanation of what it means for your real-world range, and a written result you can keep for your own records or show to a buyer or seller.
