Abstract: A device estimates the health of a battery by first collecting measurements of the battery over multiple charging and discharging cycles. Scores are assigned to the measurements according to scoring rules stored in a memory of the device. The device calculates battery based on an average of the measurements, where each measurement has an assigned score greater than a threshold.
