Battery life is a highly variable property that depends on all kinds of factors such as storage temperature and depth of discharge (DOD). During charging the reaction goes in the opposite direction producing lead oxide at the cathode. After you’ve removed all of the corrosion and dirt from the terminals, give the battery a quick rinse. It looks like a bent in half piece of metal that comes in contact with the battery. And, as always, contact us if you need any more guidance.
