Kerry, I hunted through all that mess as you apparently did....hunting for a clue that would knock the sulfide stuff off of the plates....but it continually refered to keeping the batteries in the UP condition to keep it from forming. Question: You ever heard of such a thing that will make the sulfide go away? Probably the 64 dollar question, huh? I thought I had heard rumors of it....it would save a lot of batteries and let you use them completely up as the life expectancy of the modern battery leaves a little to be desired. Fred

I was going to build my own from radioshack parts, but elected to fork out the money and buy one that was hermetically sealed. Pulsetech sold me the 120V plug-into-the wall version that they say is good for 24V, 36V, or 48V. The 12V battery circuit they use is cheaper, but may not have the sand for driving 2 12V loads in parallel, so the High Voltage version used on the 2 6TLs in series may be the better bet. The challenge in the design is achieving desired waveform and frequency. Since it pumps charge, the voltage is not a big deal.
