Jay, I saw that comment also. The more hardened lead sulfate becomes, the more resistant the battery is to the electrochemical process and therefore less current is drawn from the charge source. This decrease of load allows the charge voltage to rise more rapidly. This rapid rise is usually a

What you have there is a set of completely hammered batteries. It sounds like an off-grid system with parallel strings of batteries of different ages being chronically undercharged., which is the renewable energy equivalent of a car full of teenagers with guns and whiskey. Something bad

The sulfated cell would show an artificially high SQ reading, if she tried to add acid to it: another bogus trick people try, when their batteries are going out. You might ask. Customers often have to try every other trick in the book before admitting they need to pay for new batteries.
