Patent ID: 8330428

Claim:
A method of de-sulfating a battery comprising: connecting a de-sulfating device to a battery; applying electrical pulses to the battery using the de-sulfating device, wherein the operation of applying electrical pulses to the battery using the de-sulfating device includes selectively repeatedly activating a plurality of channel power pack modules electrically connected between an alternating current source and the battery; wherein, when activated, an individual channel power pack module provides one ON pulse to the battery, and wherein the plurality of channel power pack modules includes a first channel power pack module and a second channel power pack module; and wherein the operation of applying electrical pulses to the battery using the de-sulfating device includes alternately activating the first channel power pack module and the second channel power pack module so that together, the first channel power pack module and the second channel power pack module provide pulses including a repeating pattern including an about 0.1-1.5 ms ON pulse followed by an about 1-6 ms OFF period.
