Sourced fact
The defensible method is to record state of charge, predicted range, date and relevant conditions together.

Dashboard range method and limits on a used EV
Record the displayed state of charge and predicted range together with the date and relevant conditions. The snapshot can prove only what this vehicle displayed at that moment under the recorded conditions. It cannot measure usable battery capacity, establish State of Health or promise future range.

Key facts and evidence
For a UK used EV, reviewed 13 August 2026, a dashboard range figure is a dated vehicle display rather than a professional battery measurement. Recording state of charge and conditions makes the observation interpretable. It can evidence the displayed estimate at that moment, but it cannot establish usable capacity, battery safety, State of Health or future range.
Sourced fact
The record shows what the vehicle displayed at that time and under those stated conditions.
Sourced fact
A single display is not a measured capacity, battery-safety finding, State of Health report or future-range assurance.
Use a dashboard range display as a dated observation, not as a battery-capacity measurement or a promise of future driving range.
Method
Capture the state-of-charge and predicted-range displays together, then retain the date, vehicle identity and relevant temperature, route and charging context supplied for the observation.
What the dashboard can prove
The photograph or written record can establish the value shown by this vehicle at the recorded moment, subject to the accuracy of the accompanying identity and conditions.
What the dashboard cannot prove
It cannot establish measured usable capacity, traction-battery integrity, an independently validated State of Health value or the range a future owner will achieve.
What to do next
A dashboard range snapshot does not decide roadworthiness or authorise a test drive.
Immediate action: Record the display before relying on any seller interpretation of it.
- Do not rely on the figure if state of charge, date, vehicle identity or relevant conditions are not recorded.
Checks that stay with this vehicle
Using normal controls, record the displayed state of charge, predicted range, date and stated temperature, route and charging conditions.
The observation is tied to this vehicle, this moment and the conditions supplied with it.
Stop drawing conclusions if the vehicle identity or the display conditions cannot be established.
Professional hand-off
- Commission an independent vehicle-specific battery assessment when usable capacity or State of Health matters to the purchase.
