Lead-acid battery resistance-capacitance voltage reduction circuit diagram
Description of Acid Battery Operating Parameters
the lead–acid battery model in electric or hybrid vehicles, the charging and discharging process is of great importance, i.e., a charging/discharging voltage and state of charge (SoC) [7]. Very often the model of the lead–acid battery for the Stop-Start Technology is a circuit model with two resistance–capacitance (RC) blocks [8].
The calculation of the characteristic diagram is essential for discharging. Lead-acid batteries show a characteristic with continuously decreasing voltage when discharged with constant current. The higher the discharge current, the greater the voltage drop. Figure 1 shows the modeled discharge profile for a 600 Ah cell loaded with varying power.

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.
