How far to rely on itThe data is read straight from the car's battery system and sensors, which suits checking for faults. It does not measure capacity; the health figure is the car system's own estimate.Measured with the car's own sensors over a full charge, without taking the car's estimate directly. The report includes the measured values and the charge curve. An accuracy figure will be published once comparison data has built up.
