poppet2 Posted October 31, 2013 Share Posted October 31, 2013 If a brand new unused car battery has been sitting on the shelf for 3 years, will it still work once it has been on a 24 hour charge? Link to comment Share on other sites More sharing options...

jfish1936 Posted October 31, 2013 Share Posted October 31, 2013 This is from an advertisement: Lead Acid Battery Conditioner Removes or reduces sulphation which kills batteries. We have been looking at this product for about 5 years now. Frankly, we were skeptical. A product in a bottle that brings dead batteries back to life? Well, fact is, it does work. As many of you know, when wet-cell lead acid batteries are allowed to sit around they will sulphate up in as short a time as 6 months. The sulphate builds up on the plates and separators. This product basically dissolves the sulphation. The product is so good that the manufacturer will extend the warranty on a new battery by a year if used when the battery is new. I haven't tried to use a battery that's stood for a year, but I might expect this. Anyone with practical experience? ---------- Post added 31-10-2013 at 19:38 ---------- Also see: http://en.wikipedia.org/wiki/Lead%E2%80%93acid_battery#Sulfation_and_desulfation (sorry to use this notoriously unreliable source) Link to comment Share on other sites More sharing options...
