* the batteries were charged until this morning (4 days) when I disconnected from ground power and drove to the insurance adjuster. The batteries should have been maintained during transit at 2A. The combined batteries were providing 11.8-12.0v after 2 hours unplugged.
Good chance one of the batteries has a shorted cell or has failed.
Should hold 12.6 fairly easy when charged and disconnected.
13.8 is a slow trickle charge and still 4 days should have them very close to full. If you have a portable battery charger maybe use it on one battery at a time.
Probably looking at 2 new batteries.
