This one is 12V only, but Google shows 42,700 results for 'battery desulfator circuit OR schematic' so there are almost certainly more sophisticated circuits freely available.
Slow charge ;needs lots of hs though, but i did manage to recover a big tractor battery through the night.
A desulfator is basically just a high voltage pulse generator, when the battery receives a sudden jolt of high voltage electricity it actually knocks of some of the sulfate that has formed on your battery's lead plates and dissolves back into the electrolyte. I've built a few solid state prototypes like this one but never got any impressive results excluding my SG build, but I will give this one a go as soon as I receive the missing parts.

In the middle of building a battery charger from a computer power supply, I discovered numerous articles on battery desulfation and desulfators. 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 thought I would add this thread about how to optimize the origional kick back type desulfator.

Below shows the current paths when Q1 is off for the 1000 microsecs.When Q1 is off current flows out of the battery and into C1.
We have all been to the circus and seen the large acrobat jump on the a springboard that propels a smaller acrobat very high into the air. One of the things that would be helpful is if you had arrows for the direction of current flow, even if you added them to the pics above.
Once you have built your super inductor the next step is to adjust the pulse width to match the inductors ability to store energy. If this process is applied over a long peroid of time it can rejuvenate your sulfated dead batteries, although it does not work with all batteries it does work best on wet cell lead-acid batteries.
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. To keep clarity at maximum I am only going to talk about the output components.Below is the basic circuit of the output stage of the kick back desulfator. This page is a collection of simulations and commentary possibly leading up to a hardware project. 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. If it is not constructed correctly then the charging energy will be wasted and when the discharge cycle occures there will not be much energy to desulfate the battery. If the circuit is operating with too light of a load you won't hit saturation and will easily hit the break down voltage of your diode and Mosfet.How hot is the Mosfet running? I would like to be able to drop the charger offline, or go to a maintenance charge, using the measurement circuit.

I wound my own inductors and with a little tuning achieved over 50 amps of pulse current. This can be done by inserting a small resistor that is in parallel with a large capacitor, in series with the battery. After you reach the point where L2 saturates you will get no additional energy out of L2 no matter how long you charge it. Put this assembly in series with the battery and connect a volt meter across the 1 ohm resistor. The voltage you read will represent the current drawn by the circuit and the 1000 uF cap will average the reading. If both diodes run a lot cooler then it means you just need to buy a diode with a much higher reverse voltage.
Next remove the resistor that determines pulse width in your circuit and install a potentiometer (trim pot). If both diodes heat up the same (as with one), then the forward current is causing the heat. This pulse causes D1 to conduct which routes the energy from L2 back into the battery. This is the region where the inductor is beginning to saturate, (water is overflowing the bucket.) Adjust the pot to where it just begins to saturate, remove the pot and measure what resistance it is. The pot you put in should be at least twice the value of the typical resistor indicated in the schematic.

It's caused by a faulty connection between flat head.
