In the plot above the V(vbat) voltage is the battery voltage plus the voltage across the capacitor C1. Current through the battery, I(L5) = I(V1), is the inductor flyback current plus the current from the diode-bridge charging C1.
Since I wanted to try a desufonator, and wanted to have it supply a small charging current, and the CIP circuit seemed to do this with one less inductor than the standard desulfator circuit, I decided to model it in more detail (eventually,as I was currently working on building a bathroom, playing with LED flashlights, and working on two old cars). In the initial plot above, I had a transformer primary resistance of 5000 ohms that severely limited the output current capability. Now the circuit does looked more like the standard desufator circuit with a low-current charger attached.

The problem with the second plot is that it shows only 9 ms detween 27 and 36 ms after starting, it is not a stable circuit yet. The measurement circuit gets a reference voltage from the 555 timer for 5 seconds and compares it with the voltage across the battery. Q6 is a level shifter circuit that converts the battery voltage referened to the +voltage supply rail, into an equivalent voltage referenced to ground. I began modeling one of the circuits and playing around with the various ideas put forth in the desulfation forums.
I don't yet know if anything can be obtained from battery measurements at the planned time, as the battery voltage will likely just be the charger surface charge. It is a Everstart, from Walmart I think, and was fairly new when left to die in an unused Mustang for a year.

I will probably leave the measurement components off the circuit board until I can make some actual oscilloscope measurements. At -20 degrees, on a trip, with no voltmeter, you don't do much troubleshooting, so I just replaced the battery. I would like to be able to drop the charger offline, or go to a maintenance charge, using the measurement circuit.
