Battery

Understand the battery.

Capacity, condition, degradation and the evidence that makes a number useful.

Turn your range and consumption into an estimated usable-capacity band. See what the numbers can—and cannot—tell you.

Compare current usable capacity with the original capacity, and calculate historical average loss.

Break down a real replacement quote. No invented battery prices or automatic market valuations.

Understand the context

Understand SoH, state of charge and usable capacity—and why they should never be treated as interchangeable.

Why a single annual percentage cannot define the condition of every used EV.

Check the method, baseline and identity before relying on a battery-health percentage.

Understand capacity loss without confusing gradual ageing with a specific battery fault.

Time, distance, capacity thresholds and exclusions all matter when checking a used EV warranty.
