can i use this diagram on 6v battery?
kasyam tv made a similar circuit like this
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.
it´s true as you say, discharging this type of battery too much cost huge amounts of charge cycles and reduced life span overall. if a battery been discharged to say below 12-11,5 volts or more you can expect it to lose as much as 50 cycles and about 10% of the rated CCA, it is possible to gain some back by long time low current charge in combination with eventual pulse charges. I have been able to revive batteries that had less than 1% CCA after they been depleted to zero volts by eg a light forgotten on for a longer time, but it is tedious work with many steps that takes sometimes over a week and you could do this one or two times tops if you are lucky and you have a 50-50 chance it even gonna work again, I have my own methods of doing this and won´t go into details how this is done as I do it different for each battery depending what it needs to wake up. But even then you can´t expect a battery to be 100% again. if a battery never gets above 80% CCA after a rejuvenation I consider it unsuitable for normal use
@@Pulverrostmannen I'm a beginner in battery technology. how can I identify 50% discharge level of a battery. If you know any source to get more knowledge at this, please share with me.
Thank you

Thank you
@@achintharathnayake9922 The quickest test you can make is to use a voltmeter to check the floating voltage of the battery, it is important to not have anything using power from the battery and that it been resting a few hours after a charge to settle the voltage. A fully charged battery will have around 12,7-12,9 volts depending what type it is. If the voltage never wanna go above 12,5 even if you know it is fully charged you can expect the battery being worn.
Another method to check charge level is to use a refractometer to check the density of each cell in a normal battery with removable caps. It needs to be a battery that is not sealed and usually a standard wet cell.
A refractometer has a scale that gonna be “bad” “charge” and “good”.
Third method is to get a digital load tester and they can show you how much current the battery has left “CCA” or “EN” aka cold cranking amps. It will not show you how many amp hours a battery has left but when the current goes down it indicates a battery that is degrading with age. This type of tester will also show in percent how many percent charge a battery has and if a cell might be bad, so it is a very useful tool. But it can also give you false readings sometimes.
But testing batteries health is always very delicate if you never done it and it gonna take some time to understand every thing that can go wrong with them.
I do also check if a battery is swelled on the sides visually as it is very common they start to bulge and if these swellings is unable to be pushed inwards with your hands. If the swelling feels solid the chance is that the cells are broken either from age, over charge/discharge or even frozen at some point.
Checking the acid level in a standard battery, if an AGM is dried up is harder as there is no free liquid in them. Same for Gel types.
I think it should be possible to find educational videos on different battery types.
I can explain more but as you see it is a lot of things to learn about this topic. So I hope this was helping some
@@Pulverrostmannen First of all, Thank you very much. I learned a lot from this explanation.
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.
choke with high inductance and power and you can increase the frequency ... the oscilloscope shows the effects of these changes well
Or you canbuy a commercial chartger that allready has this functionality for not much money that is safe and makes someone else liable if something were to go wrong. Some times it is really worth it. I wold build thi circuit just for fun but using it continually I would b hesitant about.
Nice circuit, does need the schottky diode and the choke added as suggested in the above reply. NOCCO GENIUS 1,5 or 9 do this automatically. I installed a NOCCO 5 in for 2009 ford f-150 fx4 as part of my durability modifications for cold weather. I'll be adding a 600 watt coolant heater in the lower radiator hose, and a 150 watt oil pan heater pad also for extreme cold weather.
Isn't the battery a big capacitor?
@vincentrobinette1507 What value choke needs series with battery and one of the charger leads you reckon?
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.
I just purchase my Charger with a battery rejuvenation mode, variable voltage output as well.
I am an electronic engineer and this is my option to make life easier.
what charger did you buy ? Ty
I think most chargers do that now, and strangely enough they don't tell you. I got rid of one charger because I caught but sending 16-17 V to my battery. My new charger, different brand, did that too. So I investigated. They are microcontroller operated and have a high voltage desulfation mode which is switched to normal charging after. The controller detects the condition of the battery and determines the profile and mode as the battery charges and the program progresses. It's odd these manufacturers wouldn't want to advertise this function.
@@davehimlin2374 most new automatic chargers do this now.
@@davehimlin2374 some Ctek chargers have a "Recond" Mode . MXS 7.0
@@Qui-9 I mailed a mfg and he said: "Our Battery Tender products are constant voltage products and they do not allow for sulfation to build up."
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
Thanks for watching my friend 🙂
Do you have the components list? I can share one of the boards with you if you send me the list. I got the boards from JKCPCB. Cheap to make, not cheap to ship it from Honk Kong.
Cheers
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).
I need alot of these with the suggested modifications anyone can help comment and I'll get back to you.
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.
Nice, simple, and effective! Thank you, friend! SUBSCRIBED! 👍👍
Thanks for watching my friend 🙂
it would be interesting to know the science behind this. Could you provide a link perhaps?
I made this years ago and changed the frequency to Hundreds K.Hertz. I could see a difference the in battery within a week :)
What is the duty cycle ratio of the 555 pulse?
@@JB-20 if you use a good charger you almost never need to desulfate a battery you keep it charged never discharge it more then 50% and you will be fine. Also buy quality batteries and not chinese junk. If you store a good battery for too long without charging maybe the desulfater will help to get it back running but when a battery dies while in use every day and used within its parameters you cannot bring it back like that. What sometimes help wirh flooded batteries is to use a dc welder and push a lot of current and make it boil there are videos on youtube also. I did a lot of experiments with dead batteries without any success thats how i know.
@@robsonrobbi1763 Thanks for the info.
@@robsonrobbi1763 - Most automotive systems charge the battery with a "dumb" charging circuit from the alternator, which is why most battery manufacturers won't warrant past 3 years. If this were for a home power application (say, solar), then, indeed, put in a decent charger and you will get many more years out of one.
@@davestorm6718 yes i agree with you however you can just buy a smart charger and like once every few month connect it to your car battery for one or two days. Apart from that i always had luck with my car batteries they always lasted 6 to 10 years just make sure you always top it up with destilled water
What is the amplitude of the pulses??
Creative as usual, I hope you will explain to us how to design a 24VDC battery balancer
Thanks for appreciating, do you need balancer for lithium battery?
@@CreativeTechos Simple battery balancer circuit for two lead acid batteries in series would be nice.
Lithium battery balancers can be bought everywhere so not so interesting.
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.
Seriously cool bro, intital i thought it just fake,but it really works .
Thanks for watching my friend, circuit diagram pcb files link is in video description
Thank you for the idea. We could not fine decalcifying circuit so far, your is the first I saw. But I can not understand why it has been connected to battery parallel with the power supply, instead of series with powers supply. Could you please explain how the circuit operates?
It is connected parallel to charger, because the circuit is itself getting power from charger and in return it adds high amplitude current pulses to charger dc through the mosfet & diode that is supplied to battery to break sulfates,
As shown in video, you can see on oscilloscope or on multimeter what difference it adds to charger dc
@@CreativeTechos It kinda rings the bell right?
* Desulfating. There's no calcium.
Nice circuit. Q6 is a PMOS, but the symbol is drawn incorrectly.
I was confused for a while when i watch it😅. But i get to the same conclusion.
Very nice and interesting.
Can some one give the better value of the diode and induction coil values please
Inductors is 1mh & 220uh and the diode can be used 1n4007
This is all nice. If your circuit is effective why not make it into a kit so people do not have to chase around sourcing components.
I am a skeptic and looked in the past at videos of Bendini motor generators, using DC welding machines and purchasing off the shelf desulfators. These Bedini's were in vogue several years ago but the interest seems to have dropped off.
I believe that you need 15v or more to effectively desulfate a battery. In one case I own a charger inverter to operate a battery backup system. I used a BLS battery desulfator to desulfate lead acid deep cycle batteries. I set the charger to 15v but cannot conclusively say it works.
On 2 cars I bought a battery Extra (UK) desulfator and am doubtful these have had any effect.
On another car I installed a Pulsetech Power Pulse desulfator and it seems to be better than the Battery Extra because I bought two car batteries at the same time and one of them on a "Battery extra" does not seem to hold a charge like the battery on the Pulsetech. However .these batteries were purchased in 2020 and it is now early 2023.
The Bedini seemed interesting but it is not that simple to build and whether it works or not seems to be highly subjective. Same goes for the others. The thing I am most convinced about is using a DC inverter welding machine.
In your case it might be fun to build and a hassle to source parts. In the end is it better than a standard off the shelf unit? This seems to be the question that never gets answered.
Have been using one of these made by Sterling electronics on my narrowboat for over 15yrs
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.
@essmd that one you'd have to look into the actual research for.
I haven't look that deeply into it.
Bookmarked! Love this kinda stuff
Thanks for watching my friend 🙂
1:03 Q6 is upside down (and the symbol could be the wrong channel type).
The body diode is shown in the direction from BAT+ to (what must be) BAT-.
Something will pop.
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. :)

Hope you wil notice this. thanks
Would be nice to see a before and after battery too support your claim, not just a photo from the top of the cell.

Thanks for watching my friend 🙂
My sealed Lead Acid Battery is dead & bulging, would this circuit restore it to good health ?
If you fully study the chemistry of lead acid batteries you will find that they require a charging voltage of 16.2V to fully complete the charging process. Most chargers only go to 14.7 and thus they never fully desulfate during normal charging processes. How about putting a few caps in there to get above that normal 12V range. I can provide more info as desired. Thanks, Ken.
I'd be curious to hear more detail about what you're proposing.
@@sxigma Just make sure that the charging voltage or spikes exceeds 16V for some duration. Too much will end up as boiling the battery and loss of electrolyte, but if you stay beneath that level you have each charging cycle fully desulfate on its own and not require any other process. The only thing that kills batteries is the sulfate flakes that build up on the bottom of the case and short out the plates. If the buildup did not take place, they would last indefinitely.
I think that boards like this should just be a standard part of every charging system as it also continually conditions the plates. You would have to experiment w/voltage & resistance to see if you can find an auto adjusting sweet spot, but a fully charged 16.2V charging will fully complete the cycle for a 15.3V discharge.
Что Вы скажете про это czcams.com/video/gixWuw8sT9o/video.html
The capacitor will smooth the voltage spike which is the means to desulfate the battery. It is counter intuitive here.😅
Great project and very useful.
What kind of diode and fuse to use ?
It's not explained in the schematic.
Thanks from Greece
Use any schottky diode, also 1n4007 will work, fuse 2A
You can see *voltage* pulses with an oscilloscope and normal probe. You don't know how much current from the pulses actually goes into the battery especially given the output caps on the charger.

If you actually could just take off the lead plate out of the battery and put in a jar so we can see the real proof this circuit is working right in front of our eyes rather than hoping and thinking it is working but at the same time, feeling uncertain because the plate inside the battery and how the heck we know that it is the sulphate fully dissolved without look at all the surface.

I want this board full kit how to buy it
Where from you
I build a copy of this circuit using the jlcpcb printed board. It works but i need a better specification for the inductors to be used. I used two Reland Sun wire wounded inductor with are similar in shape to what is shown in the video. Using 14v charger the high energy pulses have an high voltage as expected (more than 50v) but in the 220uH inductor i measured an external temperature of 127 degree Celsius while for the 1 mH inductor the temperature is about 50 degree celsius.
Since you suggest to put this circuit connected permanently to the battery in the car i fear that having an element at 127 °C can be a potential danger in such situation as leaking acid from the battery of gasoline vapor laying around.
So my question is .. what is the temperature i should expect to measure in the inductors and what are exact specification in terms of continous Ampere handling capability and series DC resistance for the inductors.
By the way the Mosfet temperature with the heatsink and thermal paste applied is around 40 degree Celsius so it seems to be pretty normal.
I changed both inductor using FT50-77 Amidon toroids. 1 mH is 30 turn of 0.5 mm wire. 220 uH is 14 turns 0.8 mm wire. Using 1N3819 shottky as D9 the temperature in both inductors is now around 30 celsius. Mosfet is 36 celsius. The pulse frequency is 1.25 Khz. Oscilloscope AC measure shows a peak-to-peak pulse of 31.6 volt (-11.4 volt to 20.20 volt).
So if the charger DC voltage is 14.5 Volt the pulse swing from 3.1 to 34.7 Volt. The measured pulse duration is around 80 nsec.

Most smart battery chargers do this function
And it's not a miracle cure. Heavily sulphated battery plates will end up with distortions and corrosion and that is assuming you can even get ruined batteries to desulphate at all.
