Recover and revive your dead car battery with a custom constant current / constant voltage power supply.
A regular charger will not charge a battery that was siting a long time and reached a very low voltage but this can!
After bringing it to normal voltage 10v to 12V, you can continue the charge with your regular car charger.

All you needed to do was trick the initialisation of the car charger into thinking it’s going to charge a 12v battery. Once it has auto selected it’s charging profile, it will charge the battery. You can do this by connecting a 12v source to the car battery terminals and then connect the car battery charger to the terminals. Watch the display on the car battery charger auto select 12v profile and start charging, then remove your 12v source. No need to wire up a CV CC board.
I was going to comment the same but u beat me to it 👍😉
Nice video, you should leave it at 15v 300mah for 24h, that's the "maintenance" mode in many commercial chargers, it helps desulfate the battery.
there will be no cranking amps in the battery instead of making a charger buy an old type charger none processor type
I have a car battery that I use for a power inverter. It was left sitting for several months. It is only a year old. It discharged down to 4 volts. I have a smart charger with a repair mode function. It picked the battery up right away. Will it ever fully recover? Or should I use a glass packed or deep cycle marine battery? I heard those can go pretty low and come back. Getting one the same physical size may be a problem. 🐀🐾
No. That battery is likely still bad because of sulphation, which greatly reduces its capacity to start a cor or run the vehicle reliably. We're not all fooled by this nonsense. This guy should have load tested it to show you all the truth.
Exactly agree 100%.
But he told you straight it would only be good for small loads. What's the problem here?
@@kitten_processing_inc4415 I just don't like lead acids. They are dangerous to mess with. Some lithiums are too. I know a guy who lost his right arm to a lithium that exploded into the fire ball, burning him over about a fourth of his body. Lead acids are just too risky, and they are not all that economical. I have chemistry that will desulphate lead acids and make them as close to brand new, and there are other methods using high voltage to do the same, but it's all REALLY dangerous.
@@kitten_processing_inc4415 People are blind and Deaf too.... That's the problem... The channel owner clearly told that the battery is still not reliable.....
More than once I've tried to use a smart charger on batteries drained below 8v or less. They will not do it. A cheap solar charger will charge it though. Two batteries I've done this with and then installed into my cars and they work fine.
That battery will quickly drop back to 5 volts within seconds when under load...... Waste of time.
It's a big battery. It won't drop on small loads. It will also recover if repeatedly charged.
@@earumamaadu Correct...... If you just want to run lights and a couple of fans....
Your use of English is excellent. Have you spent time in the UK? Mulţumesc!
Thanks, trying to be good at it. Speaking it every day so I should be getting better by now. :/
It is normal case for most of the Bolkan people, to use everything until and over their limits :D Good video. However, I would not be able to prepare such a device and revive so dead battery. This could be done only be someone like you, with very good technical skills :) Cheers from Bulgaria :)
This is not making the battery good for the car but just to use in other projects.
A pulse charger might recover the battery to use in a car.
Could hear something was familiar to that accent. Te salut din bucuresti!
You should use 1-2A to charge for 1-3 days. Mine deeply discharged to 0V, and regular charger think the battery is bad, and doesn't charge it. Finally I have to connect to simple 12V/1A power supply to charge it up (took 2 days). Anything higher than 2A is causing my battery to surface charge, and then heat up above 30C - 40C, even leaving it for 1 week (even top up fluid level when the level is low).
+Sing-Cheong Chen I'll check that battery again soon. Want to use it for a project but don't know what the project is yet. 😬
Sing-Cheong Chen charged it for 1 day at 0,5A and the check light in the battery turned bright green again.
You are 100% right!
Will charge it more like this.
The regular battery charger stops charging and says it's full even when it's dead. The voltage just goes up and the charger thinks it's done.
@@modding9224 try to discharge it for a while and use pulse/repair mode again.
I don't think it will be good for a car start again but could use it with a solar charger or for other projects.
@@IONHowTo I had an old battery sitting for 2 years and I was wanting to use it for a battery bank with a few other batteries I have. It was showing 5 volts I put a solar charger on it for a couple days only 1.5 watts 10 volts on average depending on the sunlight. Then I put a 1amp trickle charger on it got it up to 8 volts then stepped up the charge with a regular charger after a couple days I'm almost to 13 volts. I'm getting ready to load test it. Tomorrow
@@jasonclark6194 Did it work dude??
Can you help me....
When i charge the battery, the voltage not increase.... its stuck at 9v
It's got one or more multiple bad cells it cannot be recovered. Discard the battery and buy a new 1.
My car battery died in about 3 days of non-use. Seems to have a couple of years. Do you think it can be saved, after jump starting it?
The easier was is ro put jump cables to it, and then the charger.. Most people have a set og jumper cables, but not everyone have a buck booster laying around..
Very Good.
I adapted this approach. I have 2 Roal Deep Cycle DC 31 SLA batteries in series. I left one on AC charge with a balancer to the other battery. I had also connected an optimate DC-DC charger to one of the DC batteries to keep a motorycle battery charged. A trip turned into an extended stay of 6 months. Upon my return I found that the DB circuit breaker had tripped. The voltage on both DC31 batteries was 1.45V. The battery indicator was in the black suggesting that the health was possibly ok but batteries are fully discharged.
I disconnected all loads and took the batteries out of series. The vehicle intelligent battery charger did not activate when connected to the battery. After watching this video, I decided to connect the charger to the mbike battery which was fully charged. I then connected the optimate DC-DC charger to the mbike battery and to 12V out the DC31 while mbike batt stayed on AC charge.
I measured the voltage at the DC31 terminals, the voltage fluctuated between 10 - 12.5V. I then transferred the vehicle intelligent charger from the mbike battery to the DC31 (and disconnected the DC-DC from the mbike battery). The charger started its charging cycle.
Lesson: the DC31 needed a little boost to elevate its voltage, to get the vehicle charger to cycle AC power to the batt.
Let's see if I get both battereis back to their original state.
There is no such thing in what we call "battery revival". When people learn about electrolysis then they will realize that this method will never work as we hope it to. The battery will only revive if we replace the positive part (plates) of it that dissolve through the process of electrolysis. It a wasting of time. Even you can recharge it but it will no last longer because the energy stored to it will collapse too low. The Ah (Amp/hour) will drop since some of the plates already damage and cannot store energy. So in short time the energy drained. Sorry for my bad english.
your english is great and well understood, thanks
I watched a guy fill his battery back up with distilled water and kept it on a charge while monitoring it every 15-20 min, to top up any low cells. You can see and here the electrolysis taking place. He continued until everything calmed down.
What you mentioned it's what I am experiencing. It doesn't work for me
Exactly at first i thought i had written that,had to check the name... *lol*
Agm batteries supposedly don’t lose the water in acid solution and the gas created is reabsorbed via a catalyst in the negative electrode so it can be repaired. You just gotta burn off the sulfate.. if it becomes a gas then it’ll reconstitute and go back into the fibreglass. I had a 7v 9 year old AFM. 100ah bmw made by banner. Only 5h on a 0.1c/10a charger r with another good one in parallel and it’s sitting at 11.8. 80% depth of discharge. Another two hours and it’s at 12.1. Supposedly takes 15h from 90% Dod. It’ll probably be another 10h and I’ll have a good battery.
Interesting video, I would get a better charger like a Noco Genius Charger that has a force mode to charge a battery below 1 volt, and the Genius 5 and 10 models have a repair mode for desulfation. I use a PulseTech PowerPulse passive battery desulfator on my BMW battery, they claim that their patented frequency can desulfate and make a battery last up to three times longer.
Don't do anything like this. Just upside down the lead battery. Because in due course of time, the regular bumps and thumps, qnd the gravity of course, the electrolyte settles down. Just upside down it to redistribute the electrolyte. 🤘.
You messed up the battery by putting 14.5 volts onto it. A lead acid battery must be charged with 12.6. When a battery is very low voltage it takes a long time for it to take on a charge at first. You need to discharge it by shorting the battery.
To long I just hit my battery with high bolts funny enough I’m into rc stuff so I used the same b6 charger just put on pb mode and put a car charger on it that has engine start turn on get to get volts and let regular charger do the rest
Thanks man you just saved my battery
It s dont need!......Use 12 volt 5 amp transformer...to increse the battery voltage!👍
Tou need to be more specific with the times required to charge ... and what is this diy tool?
just tried charging my vanbattery with my lipo charger and got connection break.... i thought for a second there was going to be an answer here..... so close but so far haha. ill just have to buy a proper charger an try that.
Nice video! I love your accent!! I wish I had all those fancy things all I have is a trickle charger & I’m wondering if I should disconnect it to the holders in my car & so I can put it directly on the round things... ? Idk I’m a girl I have no idea what I am doing.
Best is to get a new one and no more problems for years.
droupt your car chargers. And by normal charger. May be automat charger with custome change parametrs. I arent now how sell charagers in yor country. Bosch good charager, CTEK, or by aliexpress. but I~6 Amper. You can charage any battery.
HI Sir very nice demo. I have 12volt dc battery 26 Ah and its output voltage is ~0.50 amp show. This is in the dead stage. I am charging through solar controller the inputput voltage is ~15 volt. Pls, do the needful. Thanks.
not helpful
or just buy for 20 us a pulse repair charger.
or you could simply put it in on car for a while?
I used a small 12V motorbike battery similar way. It was still good for small point welding (I don't know what it's called in english). I changed the batteries in my drill and needed to connect them, so I just welded them together by shorting my bad car battery for just a moment on the point where I needed to weld the connection. Something like this: ruclips.net/video/o1NFbchHeM8/видео.html
Nice
point welding might be called stick welding
@billaa49 spot welding is also a very popular thing
i notice it is a calcium type battery, if memory serves me right they need a 16V charging voltage to ever be completely full
I have no idea about it. Also I never saw more than approx. 14.8 on a battery charger.
@@IONHowTo yeah that's i think as high as those chargers will go, I'm sure there are differences between brands and such
Ești roman? Se simte accentul 😂💪🏻
Da haha
Can you revive a 0.256 volts motorcycle battery? Or it's trash now ?
I'd say it's gone
@@IONHowTo land fills now
You should give it to the shop selling you the new one or search locally. Some people are looking for batteries and are willing to come and take it from you.
It gets easily recycled.
@@IONHowTo recycling is the besta
I dont think that you are showing the full video from the time the battery started to charge. When using the CV CC charger (I have the same one), 1st use the Multimeter to set the desired voltage eg 14.3 then do the same for the current eg 300ma. The thing is, these settings are when there is no load. As soon as you connect the charger to the battery the battery is going to pull down the voltage to the level it is at. Say you had 11v dead battery, the initial pull will be to that level. The CV CC charger only sets the maximum limits. As the battery charges its voltage will go higher. So in your vid at 14.51v on a multimeter (when you 1st hook it up), I think that you are showing the state of the fully charged battery.
Used the custom one only to lift the voltage enough so the car charger can recognize it and start charging.
This is actually the opposite of what you write.
A weak battery will show voltage going up fast and shows full even if it's not charging for hours as it should.
If this happens, you would have to connect a load to it then charge it again in few cycles or use a special battery pulse charger.
With the pulse charger you might be able to use it in the car but can fail again soon.
This is mostly useful for projects but not in the car.
If you really dont want to buy a new battery, pulse charger + few deep cycles would make it a lot better.
I used what I had.
@@IONHowTo I think that it is good that you have used what you had, I have very much the same components as you have. I just ordered the XT60 3.5mm pins so that I can make the same charging cables.
I really only have experience with AGM and LiFePo batteries that are down to 25% ie just under 12V (for AGM) and in that situation, the CC CV circuits work great. In such situations, the CC CV works great (esp on LiFePo batteries) the V will be pulled down to the V of the battery and the C will be maxed out ie working at CC. Once V is raised to the set V the CV will kick in and the C will start to drop off. Once that drops off to about 10% of the initial charge (eg for 2ams = > 200ma) the LiFePo battery will be fully charged.
Actually if you have an b6 hobby charger like no matter what brand you have turnigy accucell imax, they all have same working so as your battery is on 5 volts so the nearest volt for is of 6v(3p) charge it in it for a while the voltage will rise in about a minute re check the voltage while disconnecting it from the charger then choose the next highest voltage in the charger suppose it's of 7v choose 8v in chager if you select higher you get connection break or low voltage error. Just revived a battery by this way yesterday, it rose to 12.65v and then i turned it off came home from the shop. Will Charge it further tomorrow.
Sounds great! Yeah brand of charger doesn’t matter at all as long as it can charge it at that lower voltage.
Yeah, for people work being done matters . Brand doesn't. Lol
Successfully charged my battery after 2 full days of charging lol 😂 I know it's bit too long but still all i had is a 80w lipo charger and cpu psu, exclude night time lol... It's showing green in the indicator,
If am right my beast took 33+12+6k of mah (took brake because of change of low watt supply) and still charging but at 1/3 of start amp(max on my charger). Will see tomorrow at what final voltage it gonna rest at...
Voltage might go down a bit.
if it wasn’t sitting with low voltage for too long, it could work in a car. Hope it stays charged nicely!
@@IONHowTo yeah it was going a bit low bit fast when removed from charging from 13.26 to 13.13 it was lil fast but going a slowly when i checked at 13.13v not bad actually. Yes the indicator was dark when i started charging it's bright green when i left the place that's what one should expect after charging one thing for like 15 hours and putting 45+ amp into it and long wait... Will put it into car tomorrow and give it a start.
Hi after charging the battery. The voltage keep on dropping what could be the problem.
Hi 👻
Could try to leave it longer on the charger 12-24h.
If its still bad then it’s a long and dangerous story to try to bring it back.
They say impulse high current chargers can fix those but the battery can actually inflate and break with those.
New battery is the best choice.
It's got a bad cell!
very good
U should check the acid first
Modern batteries are sealed. No way to do that without destroying it.
Poooooor
The only possible way you could get a few extra voltages out of it would be to add sopheric acid drop wise....... However this will only extend it's life to a few weeks at best.
You mean sulphuric acid
Yep
So Count Dracula is giving me battery advice? That's great🙄
Yeah :/ You should visit Romania. Especially Bran castle and Brasov. But you must carry garlic when going out - for protection that is.
@Martin Macquire only 4 languages
@Martin Macquire 🤣😉
Wonder if he lives in Transylvania?🤣🤣👹
Nice video keep it up
at 13 volts how much time 🕙 do we cahrge a battery giving 4 volts to 5.6 volts to 7 or 8 volts is 30 minutes enough or 1 hour or 2 to 3 hours
Should try to leave it for at least 8-10 hours, ideally overnight.
With low current so it doesnt show it's charged too fast.
Ești român?

Great video.
Try using a Optimate Charger once your charger recognises it...
Ben thanks, I just used a regular cheap charger. I’m sure there are better ones but it’s what I have. Won’t get another one any time soon. 😅
Look up Optimate / Oxford or any other Smart chargers.
They help maintain your battery for less than the price of new battery and your battery lasts much longer.
They also help you recover older batteries
Or use a charger with startbooster and chock the battery , problem solved.
optimate doesnt charge drained dead battery
@@MrStyle-sr1yv It will charge a battery that has 5.4 volts still in it, and maybe even a little lower, I'm just charging one now that started at that voltage. Optimate 4.
Why won't it be usable in the car?
Using a special pulse charger might recover it well enough to use in the car. Shown is a way to make the battery usable for lower amp loads.
@@IONHowTo so if I recharge with 4 amp charger until showing full charge, I should be able to use in car, correct. It's been on the charger for about 18 hours. And is showing about 3/4 full.
It depends on how bad the battery is.
A "desulfator" pulse charger might fix it well enough for use in the car but it's not guaranteed.
It's not about how long but the way it's charged.
This is seriously a long drawn out video. All you had to do was connect it up to an old school NON SMART charger! They dont care what voltage is left, they will supply a constant 12-14v @ 2-8amps. Those smart chargers are only good if the battery needs a bit of a maintenance charge. You could have made this into a 10 second video using a classic charger lolol 🤦🏻♂️🤦🏻♂️🤦🏻♂️
I don't have an old charger / transformer. I used what I had. Didn't want to buy more things.
Use what you have for sure!
Constant voltage is good, impulse charger is even better.
Good advice: revived for small uses, but not strong enough for car use.
Correct .Even with 12.4 v, 4 cranks and your back to 5v. Loss of amps.
Cool
Waste of 10min goshh
I've just wasted 10 minutes of my life watching someone wasting his time. When a battery is in this condition, you can use a good 12V battery to re-activate the dead battery, Connect jump leads to the Plus to plus and Neg to Neg and leave fo 10 minutes and it will equalize, then attempt to charge it with the charger.
You are fucking awesome Mr. Dragos Ion!
Never heard of that battery brand. Looks like some Chinese made crap.
James Ebola Lasted 4 years without touching it.
The brand doesn’t matter. They all die eventually.
