Upon examining the batteries, I found that the electrolyte level in all cells of both batteries was down significantly! Let me explain that this was totally unexpected as the literature that came with the new charger installed last year promised to keep the batteries charged up without boiling them dry. Well, fortunately, none of the plates were exposed but it wouldn't have been much longer for that to have happened in my opinion.
