A novel device for removing a lead sulfate film formed on an electrode by decomposing the film into a particulate state without causing the film to come off or float, thereby recovering the performance of the lead-acid battery and prolonging the life. The electrodes of the battery are not damaged and noise is not produced externally. The device is attached to a lead-acid battery to remove the lead sulfate film formed by sulfation on an electrode of the battery. The device comprises a voltage sensor, a reference voltage generator, a voltage comparator, an operation/nonoperation switch, an oscillator, an amplifier, a waveform shaping circuit, a negative pulse current generator, and power-on indicator. A pulse current with a short pulse width causing a skin effect is outputted and thereby the surface portion of the film is concentratedly decomposed. The pulse width of the pulse current is preferably 1 microsecond or less. |
