Bedini SG notes

[Farmhand]

Pirate, I also had one battery act funny when I used a SG on it, the problem then arises that we need to avoid doing the same
thing in other ways.
I like to use batteries for experiments as well, I find when I have a battery that is sulfated if I use a pulse discharge circuit to just
get some charge on the battery, then discharge it with a decent load for a bit then immediately put it on a regular solar charge
controller they usually take current and charge up, then if I leave them for a few days and discharge again then back to the solar
charge again they come back on line. I have a large motorcycle battery and mine is sus it gases off continuously there is hardly any
room in there for electrolyte, gotta keep a good eye on that.  I like it for experiments though because it's a wet cell that is smallish.
It's the one I can grab and use. I'll look up those vids, always like a good experiment video.

I think to get really good battery charging we need to treat each battery individually, and if we are working with a "bank" we might
want to try to get all the batteries to a similar state.

Each battery will likely have a specific applied charging voltage at which the transfer of power will be best, depending on it's
state and size ect. If we have a source like solar panels then it's good to get the applied voltage to stay at the maximum power
voltage of the panels which with solar panels is known and is about 17 to 18 volts usually with a panel for charging a 12 volt battery.
However that might not be the best voltage for the transfer of power, depending on the battery and it's condition ect. .

Would be interesting to get a calculated range of best power transfer voltages for a "typical" 12 volt battery. Maybe one of the Engineers could help us to work it out.

Some say double the battery voltage or almost, but my ears tell me it's a bit less, about 20 volts for the batteries I tried, going by
when the pinging in the wires dulls. I took that as meaning the energy was taken in and not reflected so much, I could hear it.

As I have stated in another topic, ALL of my 5 Bedini type motors only gave a "surface charge"  or "empty voltage" to the charging battery.  I started out with new bats and after a little while (no matter what the meters were showing me) the run bat could no longer run the motor.  This happened with 9 volt bats and 12 volt bats...it was all the same with all of my replications.  Everything always looked good, higher voltage going into the charging battery than from the run battery but, in the end, when you swapped them out more than a few times, the motor would no longer run at all.

After my experiments with the 2 new motorcycle bats (12 volt) which cost me like $50 each, I decided to use them for other experiments but learned that they would no longer charge up using my car battery charger and, when I returned them to where I had purchased them, they tested them and said they were both "shot".

This again is my own experience and you can watch my videos at youtube by looking at Piratelabs.

I have a pile of dead batteries too from the SG. I brought the subject up at the motor shop, and the owner went ballistic about suing Bedini for all the customer batteries his plug in charger killed! I can light a 120 volt AC LED bulb off the Bedini SG charger electrodes. I think it's some kind of low ripple AC that's deadly to the lead acid battery!

The patent Bedini 6392370 is a more interesting device because it has a permanent magnet involved and if it was able to
successfully harness the energy from the magnet then it might have some possibility of showing some interesting results.
However all of my experiments with permanent magnets and "flux switching" have come up to nix so far. I've tried a few
solid state (static) ways but there are a couple of more ways I would like to try with a moving rotor involved.

Anyway if we then look to the patent 6677730 we can see the device is a "two stage (phase) capacitor pulser",
In the first stage it charges the capacitor bank by connecting the supply to the caps, then in the second stage
it disconnects the capacitor bank from the supply and connects it to the batteries to discharge the capacitor bank to the
batteries and charge them.

Basically I think this is or was the Bedini "Tesla Solar Charger" circuit  And possibly the regular wall chargers circuit as
well.

I built the circuit and first thing I noticed is that the circuit "open circuits the supply" for the time period of the second stage (phase),
which is more than likely close to 50% of the duty. (it can be adjusted as by the patent), that is fine if the supply is the grid or other
such supply that is not time dependent like the Sun.

If the circuit is used with solar panels then it effectively halves the time the panels can output power as the supply duty is
restricted to the length of one out of two phases. Any time the sun is shining and the panels are not outputting power that
power is wasted or left unharnessed would be a better term.

Not the best for a solar setup.

How the big amps are shown is simply the dumping of the capacitors charged to 20 volts or more into the battery/bank.

I think at the demo they showed like an intermittent (x) amps into the setup with a much larger amps pulsating out, and allowed
people to think it was OU. To get a big cap bank charged to over 20 volts quickly from solar panels you would need to use two panels in series, otherwise the panels struggle to charge the caps to the full voltage of the panels, the last few volts would be
slow to get on the cap bank from 12v panels (not series array) as compared to the rate of charging from 14 to 18 volts from the
same panels. A series set of panels will charge the cap bank from 14v to 24 v in quick time though and I think that is what he did.
It would more or less waste one panels output if done like that with 50% duty for each phase (stage).

There are good and relatively inexpensive desulfating Pb acid battery chargers out there.  A modest amount of pulsing to desulfate Pb acid batteries is a good thing.  Hammering on Pb acid batteries with voltage pulses way above 2.1V / cell is a good way to quickly destroy Pb acid batteries.

[Farmhand]

Yes when I desulfate my own batteries I use only 1000 uF capacitor kHz frequencies and low power only until the battery has some
charge on it or intermittently.
I have a good rejuvenating charger I bought for $110.00 it works pretty good.

I usually just let the regular solar charge controller charge the batteries for a day or two and it pulses them (in a way) when it floats
the batteries, if it's busy then I can't use that.

I'm not a fan of the very low frequency high current pulsing method. It's kinda scary.
