If you are located in any developed country, you should report these individuals to the local authorities because they are breaking several laws. If you live in a 3rd world country where this type of environmental abuse is tolerated, you have my sympathy.
As long as the circuit does that, then it will do probably as much as any other device that exists on the market.
In any case, the resonant frequency would likely be extremely high, since we are talking about (one imagines) the resonant frequency of the bonds and the atoms inside the molecules of lead sulphate. A combination of that resistor and that capacitor cannot change value fast enough for the circuit to operate at anywhere near the frequency you suggest. At some point you have to realise that the original circuit was poorly designed and that there may be more than just this one aspect.

When using the Fuse configurator one have to first have a Device = XXXXXX and the Fuse Configurator knows to which device the fuse settings will be generated.
Why after pasting to the IDE from Fuse Configurator another instance of Device = XXXXXX is generated? Towlerg - The problem you found applies to all pastes regardless of what is already in the document. I suggest others who are trialing it at present revert to the earlier version until I have resolved the problem. There is some hardware feature that is needed to program this device and PicKit2 can't be changed to do it.
I can now have a few days holiday knowing that I will return to a successful bootloader session. If you want I can dig up a full circuit diagram, as only a teaser is available on the website. Desulfation is the process of reversing the process of sulfation that occurs to a lead-acid battery over time.

The circuit as it is shown is capable of adjustable power levels at the output to accomodate more than one automotive battery at the same time.
As the circuit is primarily for test and evaluation purposes, it can be modified for enhanced safety and reduced risk of shock. If you would be able to provide additional detail on what you are seeking, it would be very helpful. Once the battery has been pulse charged enough to fully desulfate it, then you may resort to conventional charging to more quickly charge it.
I use the low power version of the basic circuit to charge my NiMH and NiCd cells (two to four in series) too. Or, it would be possible to control the AC input power to 15 Volt charger transformer with a pulse driven electronic relay. The latter option would be very easy to implement and could be built into a conventional battery charger.


Hi all,now that this thread has become 'alive' again I wonder if anyone can comment on the PDF-link I mentioned in post #9.Good or bad? When the battery discharges, some of the lead from the plates combines with the electrolyte to make lead sulfate (PbSO4) which builds up on the surface of the plates as crystals (as electrons leave the battery as electricity).

That is when I stopped looking at your circuit, even though its problems go much farther than that. Besides all the obvious voltage issues, it is driving a 1000pF gate capacitance through a 275K resistor.

I was thinking about doing something a bit more that actually monitored voltage, activate a load test..
Desulfation restores, at least partially, the ability of the battery to hold a charge over the life of the battery originally caused by sulfation).
Many versions were spawned by his design but they all accomplish the same thing, that is, they use various pulsing circuits to force the lead sulphate crystals back into the electrolyte thus rejuvenating the battery and restoring its lost capacity.
The first step is to pulse the battery for 15 seconds using a Charged-Induced-Pulse described by desufonator2. Desulfation restores, at least partially, the ability of the battery to hold a charge over the life of the battery originally caused by sulfation).
Occasionally one cell will begin to warm before the others, in which case I just let them continue pulsing until all of them are warm. The typical victims of these scams are individuals that have enough knowledge to pick out exciting keywords, but no enough knowledge to understand them. It is pushed almost exclusively by those that have a commercial interest in selling desulphators. I actually came across this anomaly myself, by accident, this morning when I was testing the compiler to see if it still works on Windows XP. I was wondering if anyone has a working project or not and felt like sharing what they know. Sulfation is the formation of large non-conductive crystals of lead(II) sulfate (PbSO4) on the battery plates.
It combines features from multiple sources and sequences through them using a simple arrangement of 555 timers.
Sulfation is the formation of large non-conductive crystals of lead(II) sulfate (PbSO4) on the battery plates.
To reverse the traditional duty cycle (mostly high going low) I've always left the cap to ground.
When the battery is next charged this process is reversed with the lead sulfate crystals breaking down - returning the lead to the plates and restoring the electrolyte to its original composition. Eventually so much of the battery plate area is unable to supply current that the battery capacity is greatly reduced. Microprocessors are great for things like this, but for many people the programming tools are not available. Eventually so much of the battery plate area is unable to supply current that the battery capacity is greatly reduced. The diode splits the charge and discharge paths into two so you get away from the normal "charge through two resistors - discharge through one" which is the reason you could never get more than 50% duty cycle.


Then I suppose there should be a rectifier bridge on the secondary site in the lower-right part of the circuit. This is a particular problem when batteries are left discharged for long periods of time and when they are deeply discharged.Lead sulfate on the plates of a battery acts like an insulator reducing the plate area in contact with electrolyte. Over time this build up of lead sulfate crystals will result in a battery which cannot hold much charge - i.e. When I switched to the AC line (I used an isolation transformer for safety) the one ohm resistor instantly burned out (with a snap). Looking at the picture of your direct drive I do not see any current limiting resistors.
It can also be used every few months to keep batteries in the best possible condition all the time. Desulfation will not bring batteries with a shorted cell or worn out plates back to their former glory, but it is a valuable tool for anyone depending on battery storage for power who cannot afford to buy new batteries.When lead sulphate crystals build up on the lead plates, it is not an easy task to remove them and thereby recondition the battery. Breaking down hardened crystal build up and dissolving cystals back into the electrolyte requires a charging voltage much higher than would ever be used to actually charge the battery. But, if you were to put this constant high voltage through the battery it would overheat, release gas, and could potentially explode. So, assuming the bulb would take care of the initial surge I put a switch across it to short it out once things were up and running.
Therefore pulse conditioning is used to give very short blasts of high voltage sufficient to shift the lead sulphate crystals without overly raising the temperature of the battery as a whole.Every lead acid battery has a resonant frequency at around 2 to 6 megahertz. I powered it up and flipped the switch and poof my 3amp fuse blew and the bulb went to full brightness (mosfets blown short I assume). If pulses of electricity (high frequency, high voltage, but low power) are sent into the battery, rhythmic beating (resonance) of the plates causes the crystalline deposits to break up and the sulphate returns to the electrolyte solution.This process takes three to four weeks typically during which time the battery must be trickle charged (in parallel with the desulphator) so that the battery ends up reconditioned and fully charged.
The one ohm resistor was - according to the schematic - only there to supress startup surges so it shouldn't be aproblem to not have it there once running (I assume).I'm thinking the circuit was actually conducting in the reverse direction as well as forward and the bulb was saving me on the reverse half cycle. Below is a video showing the lead plates inside two identical batteries - one which has been desulphating for three weeks, and one which has been left in its original sulfated condition.Note that the voltage measured across the battery terminals will drop as the desulphation takes place as the internal resistance of the cells is reduced by the clearing of the crystals on the lead plates. At the same time, the amount of charge that the battery can hold will be increasing.Build a Battery DesulfatorA DIY battery desulfator circuit originally published in the US-based Home Power magazine has been successfully made for many years all over the world. This would probably have eliminated reverse current flow if there is such a thing.Anyone got any ideas??I think I'm going to abandon this circuit specifically because of the toroid issues (and maybe the whole desulfator idea). Here are links to the instructions to build the Low Power (circuit design above, and finished example circuit pictured below) and the High Power versions of the circuit. There's too much mis-information, corrected information, and buried information to be wasting my time on these circuits. These links are to be found together with a lot of other useful information here.For more infomation about battery desulfation, click here to visit the very useful Lead Acid Battery Desulfation Newsgroup. This is the third different one I've built.BTW the battery I've been playing around with that was previously somewhat usable is now, after being on the direct drive desulfator for ten days is completely crap. Also try this link to Mikey Sklar's Mini-D 12V battery desulfator, and his second generation battery desulfator with the addition of a display and data logging.
