So, I've been thinking about battery desulfation lately. Supposedly sulfates can build up on battery plates and then they fail. I think desulfating can be done by excessive charging to the point of boiling the battery and topping off the boiled off water, or supposedly by using a charger that sends high voltage pulses during charging. What about a battery desulfation accessory, is this snake oil?
