Abstract

A quick conditioning cycle system to avoid performance degradation at the end of calibrating cycle. The quick conditioning cycle system discharges a battery to a level where battery remaining capacity is still high enough to backup memory at a guaranteed period of time. During the quick learning cycle, the battery pack is discharged from a full charge. If measured capacity exceeds a predetermined threshold (Cpc), calibration stops. Otherwise, the quick conditioning cycle system reports a defected battery when measured capacity is less than Cpc and continues discharging to a full conditioning cycle, if desired.
