@ Cap-Z-ro,
I assume you are using a 9 volt re-chargable type battery. Can you give the manufacturer and model number of the battery? I do not know if you have been following David Bowling's progress, but he found that the motor used made a big difference in his circuit.

EDIT: Sorry, I just noticed that you have already answered this.

Hmmm...not sure what to make of this.

After my trans charger topped off at 8.26 vdc, I reassembled using...

- another small DC motor along with 2 speaker coils

- my hollow coil that spits out a metal dowel when a permanent magnet is applied to it -

a bifilar torroid coil wound on what appears to be ferrite

- and one cap

Ths set up tagged an extra volt on the battery over night...reading 8.27 vdc.

The "does the motor run" questions.

No, Why?    the motor does not and will not run as there is no measurable current  passing through the motor. The Capacitors are not able to pass conventional current in this way. With the first Cap wired in series to the battery we can see the voltage of the  lead acid battery now 7.8VDC  going into the cap and  4.3 volts coming out of the Cap with no-  0.0  current that can be measured.

So I do not believe the battery is taking a real true current charge and is only showing a voltage change and little to no running amperage change of any kind. But as stated above this is what I believe and not hard fact yet. So lets see what happens in the next many days.

Ok , I am going in a different direction at the moment to see what is causing the voltage increase effect.
Process of elimination. Is it the DC motor that is causing this effect. Well lets remove the motor and find out.
Here we can see the voltage still increasing without the motor connected. I will run this for a few hours to see if this effect is stable and continuing.

Remember now that this battery was full discharged to 6.25 volts and stored for around 30 days.
The battery itself can not be climbing in charge ( Electrolytic stored self charge) because of this fact.

I sure hope you are wrong IHead...but that will be determined by someone more knowledge than me.


Something to consider relative to a previous question:

Early on in one of my arrangements that showed no results, I gave the motor a spin with my fingers...to see if possibly it would run using a manual start.

It didn't run...but my meter showed an increase in charge to the battery, which dropped back down when I stopped turning the shaft of the motor.

It wasn't what I was looking for so I didn't explore it...if I had been smart about it I should have used another DC motor to turn it, and see if there was any current gain.

I will have to see if I can duplicate the arrangement again...which may not be easy now that I know more...I may have to watch some TV to dumb myself down to my previous mental level.

Regards...
