Kits for reconditioning car batteries?

save your money this is crap you also should have a respirator and protective clothing and eyewear too, but it is unlikely you can recondition a dead battery. You have to start with a decent battery to begin with. Batteries are not that expensive, if you do the research and buy a good one to begin with a battery will last many years. First interstate, is one good company that I recommend. other than that you take your chances.
