Joule Thief

Using a Joule Thief to Charge a big 1.2v  NiCad wet cell Battery.
I am trying to discover if my JT will be able to charge up a larger battery, other than a AA 1.2v NiCad or NMh 1.2v cell.

I have a number of mid size ALEAD NiCad battery cells, each cell is 9 1/4" High x 3 1/8" wide x 4 1/2" deep
Picked up a couple and brought inside, washed the outside in suds and dried.

1st cell was  0.15volts, at least it wasn't 0v

At 12 MD I began to charge it by using my Big Joule Thief Torid with a fully charged 1.2v MH battery.

    Time         JT Cell V       ALEAD Cell V        
at 12.ooMD      1.34v                 0.15v
at 12.30pm       1.30v                 0.54v
at   1.00pm       1.28v                 0.61v
at   1.30pm       1.27v                 0.64v
at   2.00pm       1.26v                 0.66v
at   2.30pm        -------                 ------
at   3.00pm       1.25v                 0.71v
at   3.30pm       1.24v                 0.73v
at   4.00pm       1.23v                 0.74v
at   4.30pm       1.22v                 0.75v
at   5.00pm       1.20v                 0.77v
at   5.30pm       1.16v                 0.78v
at   6.00pm       1.11v                 0.79v
at   6.30pm       0.98v                 0.79v
at   7.00pm       0.67v                 0.75v  Bat voltage dropped, put a fresh AA batt in to continue charging
                                                          Ceased recording info.

well this cell seems to be coming up, but it has a very long way to go.

See 0412.jpg = Start Batt charge, AA NiMH is 1.30v
       0413.jpg = Alead 1.2v cell is charging, it has received 0.50volts, not bad as it got this from a AA battery.
       0411.jpg = How big is the Alead 1.2volt battery? Just this big, lol

I should be able to drive every JT I ever make to lite up my house lights, we shall seeeeeeeeeee.

@ General Jim:

First, if you do not like this nickname, let us know and we will not use it anymore.  I like it because it just came about, as all good nicknames do, and I think it fits.  but, speak up if you do not like it and I won't use it anymore.

Second, that is good information you have gathered there.  I may have missed it but are you also lighting an LED at the same time you are charging?  if so, those are not bad numbers. 

I was working on my Bedini for a few hours tonight.  Got the coil wound, the rotor mounted, and a few other small jobs done.  I can't wait to fire this baby up.  (I hope it runs)

i have to pass this on.  I believe it was on the comment section on youtube for one of lidmotors videos.  A guy attempted to replicate his Bedini motor and could not get it to run.  Lidmotor worked with him over the course of a few comments and still, no go.  Finally, lidmotor said...."You do realize this motor is not self starting don't you?"  The guy responded..."Really?"  The next comment said the motor was working just fine after he spun it up a bit.  Now, I am not making fun of this guy as there is no telling what I might run into that seems obvious to those that already know about it.

Good work General!

The new mk1 has 4 pickup coil of 22 turn (2 on each side 22 awg)each giving 72 dc volts.I have not played with anything else for now. Not bad for 88 turns , and 4 turn jt coil at 180.
