Therefore, advanced battery analyzers with an "alert" function (boost), Judgment, a small supply charge current to activate the safety circuit when needed and provide the deep discharged cells with energy again. Do a full charge and analysis for your Li-Ion battery. read more
By: Carrol Rogers | 2012-03-22 | College During charging, the chemical action takes place which is exactly opposite to that of discharging. Thus current in opposite direction at the time of discharge, is passed through the battery. For this the voltage applied is in excess of the voltage of the battery or cell. The battery voltage acts in opposite direction to that of the applied voltage and hence called back e.m.f. read more
