Note1：When charging complete and the adapter is still in, the battery voltage will slowly drop down.
When the voltage drop is larger than 100mV from the full voltage, the re-charging cycle will
start.
Note2：If the battery voltage during plug in is larger than 4V, the charging current will be limited to
0.25C to avoid the battery voltage overshoot.
