I've had this idea brewing for awhile that I decided to try late last season. I've decided that there's little to profit from this simple concept, especially considering that they knew of this in the early 1900s. Batteries were so poor in performance any trick to even slightly boost a battery was important.

I'm not sure if it has been forgotten, or what.

My idea was that everything is magnetic at least somewhat. That the electron exchange is like a bucket brigade. In a normal battery the bucketeers are all standing haphazard.
But by inducing a magnetic field during charging the bucketeers are aligned.
When they are aligned they work more efficiently.

So it's an electromagnet around a battery while charging. It reduces IR.

I believe I have isolated the effect as distinct from reduced ir from inductive heating.

The reduced ir remains some what even in the following day with a series of normal charges.

I'm not stressing about posting evidence because this is just too simple.
Don't believe me?
Try it.

The battery shown has been magnetically charged dozens of times.
It's over well over 300 cycles old.

I don't believe it repairs anything.
Just unlocks potential.

What's the diameter of that coil(needs work, all the turns should be aligned with each other...)....and what's the current and voltage used to energize the coil?

I assume you're using DC...right?

The old patent had the magnetic field polarity at a right angle to electron flow. I'm thinking that's how it should be.

So ideally I need to wrap a barrel and have the batteries horizontal inside.

Yeah I do stuff half assed. Trying to fix that.

The first tests I did just used extension cord around the battery...I didn't even make it round. Just wrapped it.

When I made the coil I just made a block of wood the diameter of my biggest battery.

I just put little batteries up on Legos to be the right height.

That's a 12v dc power supply for welding. It goes positive out> battery coil >positive in for battery charger.

The first test I ran the batteries own positive lead around the battery.

I realized by doing it first there would be greater amps.

I've considered magnetizing independent of charging, but my instinct is that a positive correlation between field strength and charger flow is safer.

Give me till tomorrow and I'll have that battery reading below 3 on most all the cells.

I've got an old 4s and a brand new 4s that I'll charge soon to show that I can get the ir numbers on the old (with an emf boost) one nearly as low as the new one (without emf boost).

12VDC...ok

Again, what's the diameter of your coil?

BTW, if the +12 VDC positive is connected to one end of the coil....and the other end of the coil is connected to the +12 VDC's ground, +12VDC power supply will blow a fuse.....if a current limiting resistor or such is not used.

So, what's the value of the current limiting resistor?

The value of the current is only what the cell pro is pulling.

It's in line between the +12v supply and the cell pro's +12v in put.

The diameter of my coil is irrelevant.
I just made it big enough for the battery.

Odds are that bigger is better to a point. The flux lines are the points of alignment. So the straighter the better.

"The diameter of my coil is irrelevant. "

Can't you just answer the two simple questions?

1) What is the diameter of the coil?

2) What is the current drawn by the coil? Or, instead, what is the resistance of the coil?

Don't you have a DVM handy?

I don't have a good enough multimeter to tell you what the coil draws.

Because the charger draws 4 amps without the coil in line.
And 4 amps with it in line.

Not sure what your obsession with the coil size is.
I have made two different sizes and they do the same thing roughly.

But if it will make you happy I'll measure it.
But if you're trying to duplicate anything you would want to go big enough to go around your test battery.

The net effect is enough that precision isn't necessary to demonstrate it.

So for you to demonstrate it to yourself your parameters aren't all that critical. I'm not selling anything so as I said, I'm not stressing trying to prove anything.

I promise I won't be spending any time attempting to "duplicate" it.

Just curious to know the strength of the magnetic field your coil generates

Now, what's the current drawn or the coil's resistance?

Then you just want to calculate the EMF field I'm creating?

Or just really curious if I can use a ruler?

It's measured and posted
It takes 5 seconds to read

"I don't have a good enough multimeter to tell you what the coil draws"

"It takes 5 seconds to read"

It took me <1 sec to see that you don't know....

How about the coil's resistance?

I missed where you posted that value. Sorry...

How can I tell you the coil's resistance without a multimeter that can do that?

I've looked up how to calculate IR with a ****ty multimeter and I haven't got all that sorted yet.

I'll reiterate the diameter... Though it's already up there
2 & 5/8 inches

So is there a question?
An observation?

A cancer warning?

Yes, the coil's resistance.

And how do you measure the IR of your batteries?
