    So, unless something contaminated the electrolyte, that was totally pointless. sulfuric battery acid does not wear out.

    If the batteries have been damaged with sulfation, sulfur crystals block the lead plates and reduce capacity.

      Mike90250 that's very possible but from what I had read it was likely that it could wear out over time. Also the fact I got them only knowing current state of charge and not their past maintenance I changed it out and cleaned them some of them were just fine and others had gunk removed from them. Either way I know the current state of New acid and having been serviced.

        I am seeing what you are meaning about volts to charge now. Don't ask me why I went into ignoring my percentage meter. Even after the sun goes down and I am at the 25.2 ish it holds the 100% charge and somewhat rapidly declines for about the first 20-25%. Then after than it slows down to slow/ moderate usage rate depending upon what I have plugged in. Like I said it's a learning experience.
