I have lead acid battery experience for 30+ years and experimented a lot with these pulse chargers. It can help in some cases when sulfation is not too bad already and battery has not too many cycles yet. But it won't help at all at very sulfated batteries which sits for long time empty or had too many cycles already! Every lead acid battery decades over time and amount of cycles as the PbSO4 expands a lot more than just Pb or PbO so there is mechanical stress always active at the plates. Normal car batteries are designed for high current discharge but only short time, not for cycling at all. If you discharge lead acid 50% or more it will be damaged permanently. There are special types made for PV-storage or golf carts that can take more cycles but they are much more expensive than normal car batteries.

If I may make 2 suggestions, D9 should be a Schottky diode. I recommend a 1N5819, a 1 amp, 40 volt diode. Second, I recommend that a choke be placed between the battery and one of the charger leads. Many switch mode chargers have an output capacitor, which would absorb the current pulse produced by this circuit. Adding an inductor between the charger and the battery would make it so the battery gets the full pulse current provided by this circuit.

My wife does not have a clue what is going on in this video, but she just looked up from her book and yelled "PRETTY" about the PCBs. She couldn't care less what it is or is for, just the fact that it her colors.

Which is why the bedini pulse motor actually works. I've seen many ppl say it's all a farce but I've seen it work.

Good video. For those of use that do not want to make our own desulfator, you might want to try a PulseTech PowerPulse passive battery desulfator on one of your dead batteries and see if it can recover it, Pulse Tech claims that their patented frequency they use can extend the life of a battery up to three times.
Noco Genius 5 and 10, and CTEK battery chargers have a repair mode that I believe use 16 volt pulses to desulfate a battery.

I am lost after ordering the circuit board from JLCPCB because each of the electrical component you used has lots of details which makes it semi impossible to build this battery desulfator. I would appreciate adding the part numbers you used in this video. Thanks!

Another use for the 555 this chip does everything! thanks for the schematic I made one today

[Greebstreebling]

it would be interesting to know the science behind this. Could you provide a link perhaps?

[PF-givv]

I made this years ago and changed the frequency to Hundreds K.Hertz. I could see a difference the in battery within a week :)

I have a similar device I bought off ebay. Used it a lot but is very difficult to say if it desulphates. Have read that the connection between decice and battery should be low resistance and that it may need months of treatment.
I like the tip about adding a choke as that will help mine.

Bro your vodeo is nice to see and usfull

[abhayranade]

Seriously cool bro, intital i thought it just fake, but it really works .

Nice old school circuit with old component shapes. Any modern version would use surface mount equivalents and also clear instructions on what is assumed about the charger circuit and battery size/type. The circuit is obviously too weak to work with a 1000Ah battery on a 1C charger, as might be used for big installations.

[flyingbeaver]

Thanks for posting your schematic and PCB files. I've noted the possible changes as commented below. Looks very neat, and could be very useful as an add-on to an "old school" charger. (Some modern ones have a similar circuit to this one built in).

Nice, simple, and effective! Thank you, friend! SUBSCRIBED! 👍👍

Creative as usual, I hope you will explain to us how to design a 24VDC battery balancer

So im a newbie to this stuff, With lock down i needed something to do. So i trying to learn solar system etc. I've learnt i need a battery cutoff board. But if this tool can fix the many batteries i have, i'm all for it. And as for having the boards made up to make it look smart totally sold me. But reading the comments, am i to change some parts ?. Or am i ok to go ahead and buy some boards, I can have them pre soldered ? Also, ive whacked the sub button as im loving all this. :)

the most common reasons batteries die is dendrite formation causing shorts in a cell.
while it's possible to break the short dendrite structure using such a device, it's a short term fix, the dendrites will only keep growing and short again.
a secondary reason (in wet cells) is loss of lead crystal mass from dendrites falling off and collecting in the base of the battery, which will also eventually build up to cause a short.

these are not "fixable" issues. your battery is just approaching it's end of life most likely to improper usage or charging.

Very nice. Question can I keep this connected to the vehicle on the run or should it be done outside the vehicle
