Hi guys,
I managed to fiddle a bit with scalar charger last night. I used small spool with leftover wire, 23mH. I tried smaller inductance but spikes were smaller. Battery remained unchanged during my 6hr nap. Please excuse picture quality, seems like camera has mind on her own. This is 3 transistor setup. Scope shot between E-C.

Pretty impressive ringing you got there, I guess you are on the right track
) and MJE13005 in the middle. I had to change SG oscillator cap from 2uF to 20nF. With low switching couldn't get what I have now. There is no bulb in parallel with choke. I'll work on this later today.
- from what I understand, we can maintain battery on the same level and power the load or close circuit - short the load and charge battery with spikes. What do you think?
I think it could be good idea to control base current. The only adjustment which makes a difference is duty cycle pot. I'll try LAB battery and some more LC combinations. Tricky circuit, indeed!
we wouldn't need h.v spikes anymore, just little excitation to "make battery think" that she is getting charged. This would allow us to draw from the load without disturbing battery. Is this makes any sense? Probably not. When I read John's comment again I'm sure he meant something else. I think it's a bed time for me
