Abstract
A de-sulfating device including a plurality of capacitive discharge channels selectively activatable by a control board to provide a pulse wave modulated de-sulfating current to a lead-acid battery. Some exemplary embodiments may provide a de-sulfating current comprising a repeating pattern including an about 0.75 ms ON pulse followed by an about 4.5 ms OFF period, which may be applied to the battery at an operator-adjustable peak amperage of about 0-350 amps. The extent of sulfation of the battery may be ascertained by measuring the impedance of the battery.
