I got one and have tried it out on a "dead" battery I found in the marina junk pile. It was so dead at first, I had to put an automotive charger on it overnight. Seems as though the battery minder has to sense SOME voltage, or it won't even turn on. After that, I put the battery minder on it for three days then manually activated the restore function by pushing the button. The battery now has 4 of 6 cells at full charge, but two only have 3/4 of the balls in the little hydrometer they supply with the unit floating. This is after about 6 weeks on the battery minder. Think I have a couple of shorted cells? Wonder if the battery is any good for anything, maybe non-critical items? -- __________________ Keith BE ALERT!!!! (The world needs more lerts ...)

REPLY Statistically, most of the "pulsator" companies estimate about 80% of all discarded batteries are sulfated. The remaining 20% do have real faults like yours with shorted out cells. If you can pick over the junked pile, select batteries which show some voltage as opposed to zero voltage at the terminals. Your chances of finding a sulfated but otheeise good battery is greater than way. I picked 10 batteries from a pile and only one of them would not recover with the CanPulse product that I tried. I rejected about another six which showed absolutelu no voltage and a hunch simply made me reject them as candidates. Keep trying, goo d luck. Arild
