Didn't you know we are playing clue?

Below is a schematic that does actually charge with minimal losses.



When I put the motor between the positives... it did charge the
battery, the charging battery actually got warm. I also could
here it boiling inside (charging battery).

When I put it on the negative side, just charging... no increase
temperature.

Test #6 30 minute duration
30 min rest then collect standing voltage
Battery 1 12.35v/12.35v (loss .00)
Battery 2 12.32v/12.32v (loss .00)
Battery 3 2.05v/1.95v
Battery 4 12.22V/12.47v (gain .25v)

As to the motor... no switching control (just on/off). As the
battery gets charged it slows down to just a few rpm.

Test #7 60 minute duration
60 min rest then collect standing voltage
Battery 1 12.36v/12.33v (loss .03)
Battery 2 12.33v/12.29v (loss .04)
Battery 3 1.99vv/1.97v
Battery 4 9.14v/11.61v (gain 2.24v)

Ya it would do that.
IF you have 24 volt potential on one side and a 12 volt on the other you have a 12 volt potential. If that ratio closes up then you lose that potential eventually coming to halt.
That could happen pretty quik. Your batterries based on the schematic might not even show the discharge from that small of a run.
Look at the Amp draw. If it low put a mechanical load on the motor to increase the amp draw. All your looking at is voltage. Voltage means nothing in the short term

In his case I would suspect he has found the perfect sulfated batterry.


Haven't you ever seen a battery on the charger that is sulfated? The potential can grow to the limit of the charger and shut the charger off. Or in somthing like a Bedini motor the charge may grow well over double the batteries usual potential. A 12volt may grow to 24volt while the charge is on it.

If this were to happen and say the battery were to grow up to 36 volt, when the motor was off the current would then backcharge the motor. Then you turn it back on and start over. Depending on the motor he is usings it may be internally bridged. This would alot for the motor going in the same direction. AC/DC motors fall in this group. They can run no matter what type of current you put in. And they always run in the same direction. No matter what way you charge them.

But this is probably not a good thing to try to duplicate. You may get results but good luck trying to find a battery that duplicates that. And then you better have the right kind of motor or run a bridge rectifier before your motor.

Personally I would just use 4 caps half the voltage of my battery and instead of switching off I would switch the caps to series and fire the current back into the run batteries. That is duplicatable everytime.
Or run the Tesla switch with 2 battery banks. They are easy to build. They still consume but a hell of alot slower than you would expect.4, 4 amp hour batterries running a 4 amp load will die in 4 hours. Under the mechanical tesla switch you might go 4 days. Then your shaft power could make that even longer.

Wish ya'll the best.

After reviewing the data from multiple setups I have concluded the following.

Different phenomena occurs when splitting the positive versus splitting the negatives. Every time you put in a new piece (battery/load or whatever) the results are not consistent. Motor speeds are different, current flows change... and there are times when there is no flow to readings that are off of the scale of my measuring equipment.

Does the motor charge? Well yes, and no. The motor draws a lot of current and does leave a residual charge... but so far I am not convinced that the residual charge is enough to warrant it as a beneficial catalyst mechanism.

I have no doubt that the "dead battery" needed for this experiment is in fact dead. I can run a charging cycle and watch the residual charge go up a couple of volts... only to be completely extinguished by a momentary contact of an LED.

Throughout the process, noting the ebbs and flows of current through the system is very interesting.

Although I could produce some positive results, the repeatability and consistency of it is troubling.


Footnote: The next morning upon testing and logging battery voltages I noticed Battery 1 had reversed polarity.
To just short of -11v! Was that a pun?
