State of health reports
Many cars show a battery health figure in the settings menu. Third-party tools and dealers can also run a report.
| Check | Why it matters | How |
|---|---|---|
| Battery health | Capacity left | Settings or OBD tool |
| Warranty | Coverage on high-cost part | Ask for documents |
| Charging history | Heavy fast charging adds wear | Ask the seller |
| Software updates | Affects features | Check with dealer |
Figures are typical ranges and vary by car, climate and driving style.
Ask for documents
Request service records and battery warranty details. Check that the warranty transfers to the second owner.
The battery tells you the age of the car better than the odometer does.
Test it
Charge from a low level and watch the range estimate. Try a DC fast charge to see that it performs normally.
Worth doing
- Get a battery health report
- Confirm warranty transfer
- Check charging port condition
- Test fast charging
Practical tip
A cheaper EV with low battery health can cost more later. Pay for a proper inspection.
Bottom line
A used EV can be a bargain when its battery checks out.
Specifications, prices and rules change. Confirm current details with the manufacturer or the relevant authority before you buy or repair.
