Combination capacitor/lead batteries, in which a lead acid battery is combined with a capacitors, require the simultaneous use of a pulse circuit and a capacitor. However, the problem has arisen whereby the capacitor affects the pulse circuit, and the pulse disappears. A lead acid battery is provided with a coupling device having a capacitor, a pulse circuit and a filter. Sulfation is prevented and abrupt changes in discharge current are smoothed so that the pulse waveform is not affected, greatly ameliorating the degradation of the lead acid battery. |
