Are my batteries bad?

My system has 2 6 volt AMG 200 amh Trojans, factory 300 watt Zamp panels, factory Zamp controller and Viltron BMV 712 monitor. I had the trailer plugged in for a day, then unplugged it and charged on solar the next day. That night, when dark, the batteries showed 12.98v. The next morning the batteries, still dark, showed 12.88v, just the CO detector and monitor were drawing current. Then I turned three led lights of and nothing muted changed so I turned on half the interior lights. The volts dropped to 12.66 and within 45 minutes it was at 10.64v.
The photos show the data screen info. What's up with my system? Why at 10.64v does it show 100% State of Charge and Time remaining 2d 22hr?
