The status of the battery pack is continuously monitored by the gas gauge. The gas gauge does not read the actual
charge on a battery pack, but measures and tracks the current into and out of the battery pack. The gas gauge is
synchronized to the battery pack condition by performing a full discharge cycle followed by a charge cycle. A new
battery pack must first be discharged and fully charged followed by another discharge and charge cycle. This process
continues until the remaining capacity value is close to the full charge capacity value. A recondition cycle is performed
the first time a battery pack is connected and repeated periodically. The frequency of recondition cycles is determined
