Bedini SG

[Jetijs]

You are right, I take the neon off and remove the charging battery, but only for a quick moment, because without protection those 2n3055 fry fast (depending from the setup, of course). But that quick moment is usually enough to see how big the spikes are.

Aaron, you are right about the battery size, I have never really observed this effect on small 7Ah gel cells, but I can see it on my 50Ah car battery

taking the charge off....

Ok, I did not know that is how you were looking at your spikes on the scope.... ( with the charging battery removed )

So that is why you are getting such large spikes. On the videos I see Bedini looking at his spikes hooked up to the battery, but then again he might be having caps in his setup....

I was on another board the other day, and they said something that made alot of sense to me, you can tell how sulfated a battery is by looking at the spike when it gets to the battery. On this board they made desulfators. One thing of great interest to me is they tuned the desulfator to the frequency of the sulfur. This just made tons of sense to me as to why it would be more effective to break up sulfur at its resonant freq.

Yes, the battery size is critical. They are totally different animals each type of battery, react so differently to the energizers.

Hi Mart,

How did they tune the charger to the sulphate? Interesting idea.

It is easy to guage the level of sulphation when you hook up a sulphated battery to a bedini charger. The voltage instantly goes way over the the rated level (ie. 12V would go up to around 24V), but then it will slowly fall to normal levels. Sometimes the sulphation will be so bad that all my neons light up. It's as if there is no battery on there at all. (these are the ones to toss as they will not be worth the effort)

As far as looking at the spikes on a scope, I think Bedini see more because of his scope. It's 200MHz compared to the average 20MHz.

Cheers,

Steve

I have a 60MHz scope and I all I see is an 18v spike when the charging battery is connected. The easiest way to find out how high those spikes are (IMHO) is to charge a 400v-600v capacitor since it will not charge above the actual voltage supplied.

I also wonder if leaving neon bulb connected actually absorbs some of that HV destined for the battery?.. In EFV video John Bedini actuall had a big sign in from of the energizer saying "Do NOT turn on without load". Was neon bulb removed from it?..

I haven't used any bulbs in my circuit for some time now. I always figured that if you have a bulb in line, thats using power that could be used for charging the battery. The only one that made any sense to me to leave in would be the one near the pot to keep the spike from destroying it, but I leave that one out too.

Jetijs,

I saw this over and over at John's shop. I think it is easier to see on larger battery banks since little differences are magnified compared to small differences with small battery comparisons.

This was one of the things I was hoping Sephiroth would see with his automatic load draining circuit he put together.

Hi Aaron,

I have a bigger solid state device charging 2 x 24ah batteries in parrellel and I have 2 other identical batteries I'm going to use as a control to see the difference between a conditioned and nonconditioned battery.

the charge and discharge curves are very interesting as the experiment progresses but I want to leave it running a bit longer before I post the results

Bedini updated version

Hi guys about the updated version for multi coil Bedini setup one have to add 4 diodes more (1n4007) for every coil?
Thanks

which circuit do you exactly mean?

[Guruji]

Multicoil

Hi JetiJs this is your post image the multicoil setup. Now an update of the SSG bedini was released saying to put 5 diodes in parallel to charge battery.
I would like to know if for a multicoil it's the same to every coil.
Thanks

[ABCStore]

I think the circuit posted right above is slightly incorrect. One of the 1n4001 diodes is connected before the resistor.

When you go up to high amps and high 24V and special tuned magnets or neos, the neon will not save your hide been there....

What I learned came from this forum.

Desulfator - 555 based and all pulse output stages - All - Lead Acid Battery Desulfation - Message Board - Yuku

They have some very very good ideas there about fixing old batteries.

And I bet you are right if I had a scope that could sample that fast I would be able to see soo much more about the spikes.

Another method that I have been checking into is using epson salt to break up the sulfation.

Uploaded circuit

Hi guys I was refering to this circuit. How it is applied to a multicoil setup?
5diodes to every coil?
Thanks

[Mark]

Hi Guys, off topic but wanted to throw this at you. I just put together another SG and built my rotor out of a small gyroscope. I glued 5 1/4 inch neo square magnets to the outer edge of the aluminum wheel. I took it out of its original cage and mounted it in a 3 inch plastic pipe. You have to give it a good spin to get it going but its spinning at over 2800 rpm on 12 volts and 80 mill amps. And I haven't even tuned it yet!

Think of it as 5 diodes per transistor.
