has anybody ever tried pulsetech desulphators?
i have been looking at desulphators for a few years,
i made a crude unit and drove it with my signal generator, it was rubbish but it did convince me there may be something to the idea,
i spotted a pulsetech powerpulse on ebay at a great price so i thought i would try one,
the first bettery i tested it on is a 12ah leadacid flashlight battery that was charged fully once from new then discharged and left to go flat for months, i kept telling my buddy to keep it charged at all times otherwise he would end up with a useless battery,
he did not listen and left both his lamps discharged and ended up with two useless lamps that would take no charge at all from the supplied switchmode charger or a regular car battery charger,
he gave them to me because its cheaper to buy a new lamp than a new battery over here,
i thought they were ideal to try the powerpulse, 2 batteries that could not be wornout because they have done no work but as far as joe public was concerned they were dead and going to the councill waste disposal site
i dialed in 20ma and 30v and hooked the 12ah up,
nothing dead not even making 1ma of charge current,
after about 4hrs at 30v the current slowly started to flow untill it reached 20ma where the volts started folding back,
i watched it slowly come down below 12v then i dialed in 500ma of trickle charge and set max volts at 14.5v and left it several days,
still not taking any real charge it looked like a cell was short or internal resistance was high as it would not hold even 12v under load, i tried to give it a quick blast with 6amps to give a a kick in the pants but i could not develope 6amps with only 30v max
it was time to hook up the powerpulse and keep an eye on the meters,
after 2 days of the little black box flashing its led at me the battery was taking a real charge,
i took it up to 15v and needed 112ma to maintain the battery and the powerpulse,
i slotted the battery back in the lamp to give it some real work,
2 fillaments 100w and 130w both lit and to my surprise it seems perfect again,
i put it back on charge and hooked the other battery up in parallel, only 4ah 2x6v in series,
now this battery never had balls from new and would not take any charge at all after spending far more time discharged than charged during its 4 or 5 charge lifespan,
his lamp never was as good as mine depite been the same lamp same 100w phillips bulb and been newer than mine,
there was a clear difference between our lamps and it was there from brand new,
throw in his poor charging regime
( he only charged it right before he needed to use it ) and that = another dead battery,
after starting it off at 30v untill i saw some current flowing then hooking it in parallel to desulphate along with the 12ah for 36hrs,
i can see a notable difference in brightness when i compare it to my own lamp, they are much closer in brilliance than they were before,
this thing seems to work to me,
it definately does something to a small lead acid battery that my bench supplies will not do on their own,
i have tried to revive batteries in the same or similar condition no end of times in the past and never had results like this, maybe its just a fluke but i dont think so..
