Why Get A Degradation Check Before You Buy?
Every EV battery loses capacity over time. Degradation isn't visible on a test drive, and it directly affects how far the car will actually go.
Measured, Not Estimated
We measure the battery's actual degradation using diagnostic equipment, rather than relying on the dashboard's own estimate, which can be inaccurate.
Compared To Original Spec
Your report shows exactly how the battery's current condition compares to when the vehicle was new, as a clear percentage figure.
Negotiate With Confidence
Higher-than-expected degradation should mean a lower asking price. Our report gives you the evidence to negotiate, or walk away.
Clear, Honest Report
You get a plain-English report showing degradation percentage, estimated real-world range and our honest recommendation.
