I have heard it's great for old batteries, so I guess "Warranty" would not apply. I have also heard conflicting explanations of the amount to use, but that it reduces electrolyte consumption.... I would try it when my batteries are starting to suck up too much distilled and too often. Heard to use a an eye dripper worth from one guy and a teaspoon per cell from a tech, but wouldn't want to take that to the bank as it's liable to be a with drawl.....
