A Battery Rejuvenator

[Egon]

Hmmm---any way to hook the battery up in series with my back and replace all the bone that has been lost over time? Knees could use some help to!:thumbsup:

Nope. All you would do is desulfate your bones.

To the people that have said this might prolong the life of a weak battery but not work on a dead one.
I say try it or you have no business talking about it.
I took a totally dead battery that had laid outside for several years right through our Michigan winters and all.
I could get no movement at all on my meter.
That battery was DEAD.
It started slow but it ended up just like the rest of them.
It is ALIVE!!!!!!
I am using it to jump start my daughter's car every morning now because I need to dig her battery out of her car and give it a couple days on that great rejuvinator.

OK, what ever you say:laughing:

Thank you Markcuda. Send me all of your money now. Actually go take out a $250,000 loan and send me that money.
You should be able to get a good interest rate and pay it off.
This rejuvenator is what brought me to this site and I sure am glad I found it.:laughing:

Are tractor batterys deep cycle?

 

[Rustaholic]

Not usually.
It is not good to use a truly deep cycle battery for engine starting.

I used to have a Ford 3500 Industrial tractor.
That was a three cylinder diesel.
The battery was like three good size pickup batteries.
I kept the dead battery when I sold the tractor off.
The tractor was dead too
The battery laid around five years and it only had one weak cell putting out 1 1/2 Volts.
A full week on the rejuvenator and it is holding true at 13.4 Volts.
That is a $250 battery now.
I actually did not build my rejuvenator myself.
The guy that told me about this site sold it to me because at the time I was working six ten hour days per week and I had more money than time.
I like the way he did it.
He had an old motorcycle battery charger that was dead so he gutted it. He saved the battery clamps and the power cord.
He put the diode inside and mounted a duplex plug outlet on the box.
He printed out a Rejuvenator label and placed it under the word Battery on the front of the box.
He wiped out the word Motorcycle too so it just says Battery Rejuvenator on it.
I plug a power strip into the outlet and use adapters to plug light bulbs into the power strip.
It makes a nice neat package with most of the wires protected.
Just do not clamp both clips to your tongue and plug it in.

While it is actually possible to recover sulphated batteries that are dead due to sulphation only (that does not mean you can recover one with shorted / open cells, bad buss etc.). However it is not likely to recover such a big battery in a week with a commercially sold desulphator either. I've got bigger desulfators range from kick back to plug in (mine are waaay bigger) and I can't desulphate a battery like 3 times the size of a truck battery in a week. However I can recover a regular tractor batteries or a car battery in one week with a desulphator that is plugged into the wall. My kick back ones take way longer... something like 4 to 8 weeks. The commercial ones are designed to be put on a battery and leave it. While on some of mine you could, there are others you can't as it would damage the electronics.

That battery was almost new when the tractor went down. I was more concerned with the tractor than the battery or I would have charged it back up after running it down so low trying to get the tractor started. The dead tractor then sat there at least five years outside before I sold it.
There was no way I could charge that battery. I was trying to with one of my large roll around ones set at a continuous 35 Amps. Six hours of that and it still couldn't push power into that dead battery so I pulled it out of the tractor and put it on the floor in my engine shed. It sat there in that state several more years until I got this rejuvenator. I didn't have much hope for it but after a full week I had bright light bulbs most of the week so I unhooked it and tested it at 13.4 Volts. I left it set a full day and it was still right there at 13.4 Volts so I put one of my little float level chargers on it. That was the first battery I tried to rejuvenate. I thought I would need to put a charger on it after the rejuvenator but I didn't. I brought back several week ones then I grabbed the worse battery I had without a busted case. It was totally dead.
It was tougher to get going than that huge battery but it is powerful now.

Are tractor batterys deep cycle?

No. Marine applications use a starting battery for what the name implies, and a deep cycle battery for items that go from a high state of charge to a low state numerous times. Marine deep cycle batteries have more and heavier plates, more lead, to hold a charge longer and not drain down to nothing as quickly as a starting battery. Starting batteries need higher cranking amps to turn over high draw motors upon demand to start.

Can this method be applied to 240v AC supply

I've read thru this thread a couple of times, and it makes sense to me. I bought an old golf cart at an estate auction, and discovered that the thing had set in the barn for several years. I tried several different things that I read on the internet, including adding the edta. Only had one out of the 6 that held any charge at all, and it wasn't much. So I built the ckt, and hooked it up to one of the 6 volt golf cart batteries today. I did add a fuse in line, and used 2 keyless ceramic sockets wired in parallel, and added a double pole switch, so that both sides of the line are isolated when power is turned off. I put the battery in a plastic tote w/lid outside put on the lid, plugged in the ckt, stood back and turned on the switch. I have one 100watt bulb installed, and it came on rather dimly, but in a few minutes is quite bright. I'll keep everybody posted as to what the outcome is. I do have a question for Etpilot: HOW DO YOU KNOW WHEN TO DISCONNECT THE CKT?

The more bulbs the faster it works. Four is the most I have ever used. As to when to remove it, I give them a couple days of the bulbs bright then unhook it and check the voltage of the battery. Ideally all of us that have one of these would also have a nice load pile battery tester.
What I have right now is a mid-size car battery side post only but it has been setting inside for almost two full years with a low charge.
I put my little 6 Amp smart charger on it and it took about 14 hours to charge it up to where it said it was full. I am taking it to town tomorrow to have it load tested free then because it sat around low that much I am going to hook it up to my rejuvinator for a couple days then have it tested again.
I took it off that charger and it has just been setting there for a week now. I need to check it tonight just to see if held that charge.

I have a brand new load tester, still in the box (HF I'm afraid) but looks like it was designed for 12v batteries. I'll try it and see if I can extrapolate. I don't see where anyone has used this setup on 6v batteries. Right now, the single 100w bulb looks like about a 40w. Will it get brighter as it charges? I'm not real sure what is happening here. As you add more light bulbs in parallel, the resistance goes down: Rt=1/R1 + 1/R2 etc. Since the resistance of the light bulb changes with temp, I would think it would be impossible to calculate Rt. However, I=E/R so as
R goes down, I goes up. Are you saying the more current we draw thru the battery, the faster it desulphates?

Others have already stated it better than I can so I will just say the more pulsing current you hit it with the faster it will work.
When our summer gets here I have a couple 6 Volt ones that I need to try it on. The one in an old Allis Chalmers tractor will be first.

Sure but why no link and do you KNOW it works as good as this one we can build from scrap and a cheap Radio Shack diode?

I left my newly built de-sulphater hooked up and outside last nite. Woke up about midnight and it was raining hard. This morning, no light, so I figured it got wet and blew the fuse. Found that the bulb was cracked and had water inside. Guess cold rain and a hot bulb didn't mix. I'll hook it back up today, inside I guess.

You left such a valuable tool outside?
I hope it is okay.
