Safety of charging 12v or 6v?

[CosmicFarmer]

Hello, this is just a question I had to ask because I did not know who else would know :-)

I would like to charge a 6volt with a fuji CFL circuit, but instead of the CFL, have the battery being charged. Would the high voltage harm the battery, or desulphate it? like the SSG does? Same procedure, almost... charge an inductor and put the collapse in battery...

Would it matter if I put 6v or 12v SLA over the ~500v fuji output?

Or even a joule theif, if one could be made big enough. Has someone charged a 6v or 12v with a joule theif?

Thanks. Just trying to design a battery charger powered from ground rod. Has anyone done that yet?

I have been playing with the same question the bulb flashers at 300volt on the cap but the time it take to charge is long. i think it better to use a relay and transformer backward for a faster charger.

I am trying the same thing. AAA fuji circuit running on a wall wart on the 1.5V setting, running at 2.3VDC. The electrolytic cap was removed and an old Energizer 12V SLA car battery placed where the cap was. Voltmeter reads 508V before battery is connected. Battery Voltage initially rises to ~12.7V and slowly decreases to ~12.4V. I believe this is the result of the battery initially having a high internal resistance, and gradually this is decreasing.
I was charging/desulfating the same battery before this experiment with an 80mm imhotep fan radiant oscillator, which operates at a much lower frequency. The fuji circuit outputs higher Voltage at a much higher frequency, and seems to charge the battery faster. It's been charging for a few hours so far. I will post the results when I see them.
Circuit and battery remain at a cool temperature.

So far my experience has been that with an IMHOTEP CFL radiant circuit charging utilizing HV, the battery (once dead) would not charge conventionally and it wasn't until I pulse it (with current) then it came back to charge. The following time, I charge it on High, i.e. 15V instead of 13-14. Now it is back to normal.
