- I have heard and seen a lot about desulfators, But do they work and what do they do? Together with my two cousins, we setup and see how the signal from a desulfator on a Oscilloscope (Rigol DS1052E)
If you want My PlayHouse Desulfator Kit 1.1, it can be ordered here : www.myplayhous...
_______________________________________________________
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.
Sooooo many things done wrong on this video its comical...... AGM (absorbed glass mat also called starved electrolyte) is a special glass mat designed to wick the battery electrolyte between the battery plates, the plates are saturated with acid to about 95% of what they can hold. They contain only enough liquid to keep the mat wet with electrolyte so if the battery is broken no free liquid is available to leak out this is why the cells look dry but really they are not. +1 for getting stuck tho!
Please help me learn more. Please give more reference where I can learn more abt these
thanks for testing very cool
Hi +Frans van schie
Thank you for watching! :-)
Part of the equation here is that the battery itself acts like a giant electrolytic capacitor.
The desulfator has to have adequate energy capability to overcome that capacitance.
A desulfator circuit that can produce a high voltage, but without enough energy, will not produce as big a spike.
(ie, a large desulfator that does not have as high a spike, may outperform a smaller one with a bigger spike, when connected to the battery. The smaller one may loose that voltage when connected to the battery, whereas the larger one can retain most of it's voltage spike.)
The waveform you took is most representative when taken at the battery posts. At the desulfator, the leads are somewhat isolating it from the batteries' capacitance.
If you charge AND desulfate simultaneously, you should have a choke (coil) in one of the charger leads, or else you are ALSO pulsing the charger diodes, perhaps detrimentally. Or probably just driving the charger monitor nuts, on digital chargers...

Hi troubleshooter1975
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
best way to rejuvenate a battery:
discharge the battery to 11 volts ( under load) disconnect this load ( for a car battery fore xample a 50 watt h4 lamp) wait 5 min to see the battery recover by itself, then recharge is - slow- thus with low amps say 2 ah with a voltage of 17....this will eventualy overcharge the battery above gassing voltage ( 14.4) for a wet or AGM type, leaf this charge on for the night mayby with a desulfator parallel, then repeat the discharging again till 11volts, then repeat, remember charging a battery is really nothhing else than desulvating itself, a GOOD desulfater can inly assist you in the proces, cycling a battery will get the capacity up!
assuming there are no other problems with your battery, hope this helps!
Hi
How long would you charge the battery with 17Volt ?
Thank you for watching! :-)
He wrote: about 6 hours - "17 volt overcharge on for around six ours"
" cycling a battery will get the capacity up!"
I can not agree with that - because every datasheet states limited cycle life. Every cycle reduces battery life.
Hi Morten, the first two to three cycles i would put the 17 volt overcharge on for around six ours, then measure the time for the discharge wirh your load, as soon as you see it improving i would lower the voltage during the following cycles, this depends on the state of battery ofcourse...
Hi
Okay thanks for you input :-)

You don't put water into absorbent glass matt
Hi Iamsuccess pro
Thank You very much! glad you liked the video :-)

I guess your power supply didn't like the voltage spike from the desulfator which would perhaps explain why it went off. Knowing what the desulfator does, adding a diode at the output of the power supply would block incoming spikes, although you would need to increase the power supply output to compensate for the diode voltage drop. I'm not too sure how that would go with a charger as I don't know if the charger actually reads the battery voltage. If it does, having a diode in the way may prevent it from charging as it wouldn't be able to do the reading because of the diode. That would potentially explain why some people are using basic chargers and not the intelligent ones when dealing with some type of desulfators.

What you didn't mention in the video is that while you showed the water levels were low all the cells where badly sulphated, what would have been a good idea was to show the cells after de sulphating to show the difference on the plates
HI *****
It´s realy hard to film that,,, and i realy havent had mutch success,,, i now use a battery analyzer

This was a long time ago so you may know now, but AGM does not use water.
Hi monono954

Why would you leave the desulfator connected while you are charging? It seems the spike could damage the charger. Also, to manually desulfate, why not just leave the charger on something high like 2.75V per cell for maybe 15 minutes, then disconnect for 15 minutes, and keep repeating for maybe 8 hours, possibly draining the battery some so it doesn't overcharge.
Hi +David James
Well there are so many opinions on how to do this,, and it does not seem to be an exact science.
Thank you for watching! :-)
Is ita really working?!
So ,Why some companies making big machines as the size of refrigerator.....
I do not have any guarantees that it works..
Hello,♥️ thanks for the video. How long does the sulfur removal device for a car battery 75 amp take, 24 hours, 3 days, or a week?? ✅♥️
We are closer to 14 days
I'm pretty sure you aren't suppose to put water inside an AGM. Those were most likely safety vents in case of accidental overcharge. Why not research before doing something potentially damaging/dangerous like that?
Hi Mike Scudero
What would you put in them,, they do dry up!
Thank you for watching! :-)
My PlayHouse I believe it's supposed to be dry. The electrolyte is absorbed into the glass mat. Preventing liquid spillage in case the battery were to be dropped or tipped over.
HI Mike Scudero
The batteries are not supposed to be serviced, but they are not dry,, they contain a gel to keep them wet. That gel does evaporates over time and the battery deteriorat in capacity. Also why there are "vents" in each cell. So the idear was to vetten the gel again.
Thank you for watching! :-)
How was the battery afterwards?
Perhaps put acid in instead of distilled water.

Where did you get the desulfator on Mounting battery desulfator and chek on Oscilloscope - 134 let me know if you can. Is it one of the better desulfator?
Hi Lorne kinnee
Thank You very much! My cousin build that one.
Thank you for watching! :-)
Oh, no results ? You think it helped that battery somehow that started in unknown state to get into another unknown state 🙂
It's really hard to be sure,,what was good and bad.
big one
Hi +73 SUPERGLIDE
I am confused, what do you mean?
Thank you for watching! :-)
what to buy one but ho to buy them from is the question
Hi 73 SUPERGLIDE
Well that is the problem,, finding good desulfators to a price,,we want to pay.. these are home made. :-/
Thank you for watching! :-)
how is that a discharge? is it a discharge when go down to 0 then go back up???? on and off on and off

7:46 The English term for the German word "Spule" is NOT 'spule' just with an English pronunciation, but COIL.
The desulfator circuit would be a nice plus. Its Probably a 555 timer with a switching MOSFET for the coil and diode thing right?
Hi cue108
Thank You very much! glad you liked the video :-)

AGM batteries are supposed to be dry.. they are dry gel batteries.. addidng water just ruin them.
They do dry up over years.. But I did add way to much.
Hi how much we keep a desulfator conected? Do we have a discharge voltage limit or?
use it with a charger,,, and use it like 14 days, and then disconnect for a couple of months.
17 volt spike doesn't seem like much?
I would have imagined at least 100 volts.
I think it is difficult to get to 100 volt.
@@MyPlayHouse Super talented, Super Vunerable.
But, will it reduce top mossing?
I do not know.
Does he sell this desulfator??
Hi Jonas Hedenberg
I do not,, but have been thinking about doing something like that..

Hi +donald laisure (73SuperGlide62)
What do you mean?
Thank you for watching! :-)
Thats a Damped oscillation... Why is that so?
Hi Outta Syllabus
I do not understand..
Thank you for watching! :-)
lead acid battery plates can act like a capacitor with surface charge, not ion charge, so a dump from an inductor can set up an LC underdamped oscillation
Mayb video how to make one

For your battery, do not be good, clen desulfator, nor, home-made desulfator! your batteries, have earplugs! for them, be good: overcharger: battery charger at 15.8V to 16.2v! and THEN see how they recover power and sulfate disappear. This way to be Make desulphation. Throw it in the toilet, all those objects! They just fantasy! They created for VRLA battery that no power watering with water! Now do you understand? I hope you have learned something from me! study, you do not play!
HI +Luca di paolonicola
I do get some of it,,
