The equivalent circuit for sealed lead/acid battery has been deduced from the mechanism of electrode reaction. It consists of eight elements,namely ohmic resistance of battery RI.lead inductance L, double layer capacitance of electrode Cd .electrochemical reaction resistance Rr,reacta t capacitance C2, formation resistance of PbSO4 crystals Rc, product capacitance Cc and warburg in pedance W. The impedance values calculated from the equivalent circuit are satisfactorily fitting to the 'xperimental data for the battery(6V4Ah)in the range of frequences 0. 05Hz~12. 6kHz. It has been prov ded that the variations for values of elements are dependent on the residual capacities of the battery.There is a turning point at residual capacity 40% for the variations of RI,Rr.Cd and Cg.
