Disclaimer

Last updated 2026-10-20

This website is for general information only. It is not professional, mechanical, legal, financial or purchasing advice, and nothing on it is a guarantee of the condition, range, value or remaining life of any vehicle or battery.

• Battery health varies widely between individual cars of the same model, even at the same age and mileage, depending on climate, charging habits, use, software and manufacturing variation.
• Our figures are medians, averages or single-car reports compiled from third-party sources. They may contain errors, may be out of date, and may not represent cars in your country.
• Different measurement methods give different SoH values for the same car.
• Warranty summaries are simplified; the manufacturer's official terms for the specific vehicle always apply.
• Owner-contributed data is self-reported and reviewed only for plausibility.

Before buying a used EV, get the specific vehicle independently inspected and its battery tested, and check the warranty status with the manufacturer. To the extent permitted by law we accept no liability for decisions made using this site.

Trademarks: vehicle makes and model names (e.g. Nissan, Tesla, Hyundai, Kia, Volkswagen, BMW, Renault, MG, BYD) and the names of test providers and data sources are trademarks of their respective owners. We use them only to identify the vehicles and sources discussed. We do not use their logos, and we are not affiliated with, sponsored or endorsed by any manufacturer, dealer or data source.
