Brief Description. Most lead acid battery desulfators out there use a flyback design with inductors. While this does work, the inductor can only hold so much energy each pulse. If the battery has a high resistance, that energy won''t be absorbed very well and will show up as a very high voltage spike on an oscilloscope.
