# Buying a used hybrid: battery questions

A used hybrid's odometer and auction grade do not establish battery health. Ask what testing, service history and warranty documents exist for the specific car, and consider a specialist inspection.

## Ask what was actually measured

A model name, age, odometer or auction grade cannot stand in for a measured battery result. If a seller cites battery health, ask for the test date, method and written result. If none exists, treat its condition as unknown.

## Compare the whole car

Review the service history, warning lights, fuel economy label, tyre condition and any warranty terms. The energy label is an estimate for comparison; actual costs depend on how and where you drive.

## Decide with evidence

A specialist inspection can identify concerns before purchase. Ask which inspection and service records Motor Traders can supply for the vehicle you want.
