Thanks for this video. There are many ways to not use the inverter IC: Simple NPN or N-FET to invert the 555 output, or use two diodes in the resistor timing path (this allows for separate on/off times), or use a P-fet and other ways.

it is also possible to implement a similar functioning circuit with a single IC using a PWM chip such as TL494 or SG352X to control duty cycle to around 10% or so, thus eliminating the need for the extra inverter chip with all the other component function remaining the same

As always... Great video and was ready to do some research on recovery of old batteries. Great timing!! Thank you

This is the best video on desulfator circuit, very good you show the output on the scope!!

Tried this circuit, it works. Great job.

Your channel is mine of knowledge for Me. From Poland with love :)

Really nice work, dude! Really useful! 😊

No, 555 ic allows duty cycle lower than 50%, just connect a diode from pin 7 to pin 6 or pin 2 and that's it.

Your voice is so great and your videos are the best!

I have experimenting with astable multivibrator for the frequency generator instead of 555 and the inverters. It works great and is very simple to build.

Good job making the video, it was very informative. I use a Pulse Tech PowerPulse passive desulfator, they claim to have a patented frequency they use to desulfate batteries, I have been using it on my BMW battery for the past three years and never have any issue's starting even though I only drive about 25 miles per week.

I have made it and it works. Thank you so much Kasyan TV.

your explanation was awesome

Thanks for the schematics...... looking forward more helpful videos

Very nice I will have to make one as I have a 12 volt battery that needs some love, thank you for your hard work and video

Great content and presentation

nice work!

This project is very good!

Good and detailed explanation 👍 thxs

DIY desulfator. This is what I need!!!

Really helpful , many thanks ....

the true inventor. and i trust this channel.

Pls make another video soon on the results and report while using this desulfator...waiting for it.

great video!!!! Tank you!!!!

Nice vocal. Beautiful

Thank you ... good explanation

In video is lot of miss-understoods...... 1. 555 can make 5 to 95 % PWM with out problem... 2. mosfet is CAP... with 500p - 1nF ... you can supply with every signal (TTL) if u have high impedance just put resistor between this can, so charge process- on state will be slower... for. ex.: micro-controller can make 20mA of output.... We can say that we will use only 15mA R=U/I =5 / 0,015 = 333,33 ohm.....the close in E... will be 330 if you know that Cap is 1nano Farad, and Current = 15mA, Mosfet will be active after 333ns, with is really nothing when you play with 1KHz t = C*U / I t = 1nF * 5V / 15mA t= 333 ns There is good way to use inverter, but for 100KHz swithing time when you need to low down power-loosses during swithing. but if you compere a 333nS or less for 3V TshV, and to 1mili S... this is less than 0,1% of working time. I looks like you take something form the Net and try to explain what is what, bu you didnot engineer this, just copy and paste, but you are talking like it was your project...

Thank for sharing this video

Great video thanks

thank u madam..2 weeks continuously with the circuit or along with charger

Thank you 👍👍👍👍👍

Excellent

Der Desulfator wird ganz einfach verbessert, indem man die Leiterbahnen vom Schutzlack befreit und zusätzlich verzinnt zum 100uF C1, zum IRF 3205 , zur Spule und die Leiterbahnen zum Plus und Minuspool. Zusätzlich noch 1,5mm2 Gauge 14 zum Akku und größere Krokodilklemmen.

Lead sulfate, when it falls off the plates, will reduce capacity and destroy the battery. More a problem with wet types as opposed to SLA with the electrolyte as a gel.

Good!

Only 1resistance connect on pin no. 5 to ground we can get reduce the duty cycle of 555 timer ic. In this case ground to pin no. 5, 1k resistor sufficient. And 8 to 7 pin should be 1k resistor।

I love your videos, I watch so many of them. And I try to watch the ads on videos of youtubers I like such as yourself. But, 7 ads in one video is getting a little out of hand for a

Very nice channel, nice project, nice voice;) ... just maybe the explanation about the role of C1 in the circuit is a bit incomplete.

Thanks. ..super 👍

cmon guys this guy give you idea on your battery dont redicule person trying to help

Great video, as always very useful. I am considering building this project. I wanted to check-back for your experience....now that we are 5 years later. Could you recover many batteries? or did they have other issues? thank you /chriV

The only restriction of a 555 timer, is it can't produce 50% duty cycle pwm. Lower or higher is not a problem. You don't need an inverter. Produce 10% pulses instead of 90% and directly drive the mosfet.

First of all your explaining method is too good. Please help me how I can make boost power supply 3V input 12V output required for Fan. Fan current is 700mA. Thanks

While it is true that the 555 can be driven below 50% duty cycle using diodes, I do think a CD4049 makes a better gate driver than the 555 output, so kind of a two-birds-one-stone type thing.

disconnect pin 7 of 555, remove R2, connect R3 from pin 6 to pin 3, now you have 50% duty cycle. connect r3 from pin6 to pin 3 with diode, connect another diode from pin3 to new resistor to pin 6, now change new resistor to change duty cycle to 10%

Hmm, I wonder if you could make SO3 (and H2SO4 in turn) this way?

Hmmmm basically Boost converter with 10% duty cycle

HER508 diode is not available in market, can you please recommend the alternate diode for it.

thanks

simple pic or arduino project with flexibility of code control

Your links to the products are broken..

NOCO makes a battery charger with a desulfator at a very reasonable price: NOCO GENIUS2, 2A Smart Car Battery Charger, 6V and 12V Portable Automotive Charger, Battery Maintainer, Trickle Charger and Desulfator for AGM, Lithium (LiFePO4), Motorcycle and Deep Cycle Batteries

Dear madame, your channel is very useful to me.please make a video , how to convert 12v dc battery to 12-0-12 dc dual supply. Thank you. Thank you so much.

I .tried it with ne555 only it works 1.3khz pin8 to pin7 10k pin7 to pin6 100k with in4148 diode paralled with the 100k resistor and 1k to pin 3 to gate using 10nf capacitor pin2 to gnd and 10nf pin5 to gnd it works 9duty cycle

Please make a BMS topology

Hi I have a question! in the circuit diagram you displayed it shows that pin no 8 of CD4049 is connected to ground, but in the printed circuit board it shows no 16 is connected to ground instead while no 8 is not connected at all. I am a bit confused, which one is correct?

i made this circuit without the 4049 and tried it on my 12v car battery which wasn't charging beyond 8.5 volts... after a week, i tried charging the battery again... lo and behold, i got 11.4 volts! putting it back again on the desulfator for another week... and then test it again after charging if it can turn an engine over...

nice

Far as I know, its the high discharge that cleans the plates up, not a charge or pulse charge. It needs to be a high current pulse discharge instead. Has anyone made this circuit and actually repaired the battery???

Why dont you just use a simple npn transistor to flip the signal?

Hello, I was looking at the schematic and I see that the 100uf capacitor in the video is placed in the opposite direction. I'm wrong?

download archive link is not working

J'ai remarqué une autre erreur que vous avez faites. Vous avez soudé la broche n°16 du CD4049 au GND alors que le shéma indique la broche N°8 ! ! ! Pourquoi ?

How to make that 200uh inductor?

How are the circuit and battery going after several days of desulfating? Any feedback please.

Can I use a 74n04 not logic gate instead of cd4049

Can we use toroid coil more than 200 uh?

so the voltage will increase to high volts...

It simpler to use p type mosfet instead 4049 inverting buffer...

where can i buy this device

51 batteries manufacturers doesn't like this video....

Is it wrong circuit? I want to make it

Why this R1 limiting the NE555 voltage supply, since it can be perfectly povered at 12V? Furthermore, CD 4049 is absolutely useless if you adjust NE555 duty cycle that, with a different configuration from this, can be set from 10 to 90%

What this circuit do for battery ..why you charge in direct by transformer ...what frequency do for battery

The circuit basically a boost converter Without feedback circuit and output capacitor...nice video though

Kaysan TV, please tellme where can i find the cicuit diagram???

Interesting! 😁

👍👏

Is anyone assembling and selling these?

If the unloaded voltage of the battery is 12v, it is practically empty.

Can you make tesla meter for the number of design wind turbines .. I need it very much and I have a lot of waiting

Thair is a rating for cranking amps if you're car requisers more thain batreys is rated for will not start the car even if it has 12v

I don't have the application to open lay6 extension, so I just take a look carefully to the pcb in the video in order to copy the layout... something strange is in the schema CD4049 pin 8 is grounded, but in the pcb (in the video) pin 9 is grounded.... I can not proceed to make one... (sigh...)

leeeed plate, oh ok

Interesting but what makes this superior to commercially available desulfators. For example ,I own one "BLS desulfator", "two Battery Extras" and one PulseTech Power Pulse PP-12L. All of these are permanently connected to 12v batteries. My first question is how is this circuit superior to these commercially available models? How one compares to the others, is, in my opinion subjective. I can only say that on two cars with a Battery Extra on one and a Pulse Tech on the other that after 18 months with the same batteries purchased at the same date; the Battery Extra setup showed issues on a load tester, while the Pulse Tech did not. Do these products really extend battery life? Hard to say. I have the same questions about this circuit. For most of us it is easier simply to buy something off the shelf as opposed to chasing around looking for components. Then at the end of the day you can see the pulses on the scope but do these really desulfate a battery?

the unused inputs on the hex inverter ought to be grounded

can this work on lithium cells? i have a bunch of cells with good capacity but bad discharge current after a few seconds under load

il semble que vous avez fait une erreur sur la résistance R3 . Vous avez soudé une 39 Ohms et il fallait selon le schéma que vous donnez une 39k Ohms... Regardez votre vidéo à 10'08"

i tested it it draws more than 1A b4 connect to battery and not more than 27V output and the mosfet become too hot ....

How to replace CD4049UBE with a proper transistor circuit?

I built this. It does not work for me. No pulsing at all. One thing I did differently was grounding the unused inputs on the CD4049 per advice from electronics forums.

While the circuit is not the ideal way to accomplish the goal, her accent makes up for that ten fold. Da PIMP (which stands for 'Power In My Pocket') is a simpler and cleaner desolator. No affiliation. Nor do I even know where to get one, but videos are on YT.

funny naration 😂 why girl ?!

My guess high temps destroys by warping plates and removing electrolyte. and going flat destroys by sulphation. Over charging also removes water/acid. De Sulphating hard sulphate deposits, you need a higher voltage across each cell and therefore a high current but this causes heat/high temps, which removes electrolyte and warps plates. So you use a DC welder, but only for 15 seconds, Then let the battery cool and have another 15 seconds go in 2 hours time checking the CCA after each try and a trickle charge in between. Keep repeating this while the CCA increases. But once this stops going up quit. with a trickle charge in between. Using a trickle charger with an amp meter. Stop charging once the charge current drops to about an amp so as not to over charge and loose electrolyte. I have had some success doing this, getting a change from 50 CCA to 325 CCA, but Chinese desulphating charger ()*&Q^(#*&%()#*&^%_)(*&%_)(*+%_)#????????. You also need a load tester or something to measure the CCA. I have seen U tube videos of people bring batteries to the boil, but this would remove electrolyte and or warp plates, Since most 12Volt car batteries are maintenance free, You can't top up with out surgery on the battery case somehow. So look after the electrolyte you have My 2 cents worth. And don't electrocute yourself with your welder. Electricity is heart stopping stuff. a tenth of an amp for a tenth of a second can stop your heart, Your welder produce 60-160 amps your car battery like wise with even more amps, Extra low voltage like DC12-25 volts can still be deadly.

There is no current path for the inductor if you run this without a battery connected. So It will probably blow up.

Basic boost converter

It can't work anymore due to plates are packed today too tight together. Therefore sulfate can't drop. I did it.

links wont work

Hi I've tried Infinitum desulfators and even made my own. No luck and the infinitum desulfator was 50 AUD? absolutely ridiculous. I need your desulfator bad! Any reply appreciated cheers from Australia just subbed.nice work love it so much 🙂👍👍👍

Do not see the need for the CD4049 .....just change the Duty Cycle of the 555
