*1. Temperature coefficient for detection and release voltage is applied to overcharge detection voltage n, overcharge release voltage n,
overdischarge detection voltage n, and overdischarge release voltage n.
*2. Temperature coefficient for overcurrent detection voltage is applied to over current detection voltage 1 and 2.
