More battery basics.
Good Day, I have a few questions Is it better for a deep cycle camper battery to be kept in a constant state of fully charged using a better tender, or better to let the battery slowly drain low,...

It seems the the tender I'm trying charges with more voltage then the camper does plugged into shore power with the battery switch on?
I have the battery switch OFF, the camper plugged into shore, and the tender plugged into one of the camper 120 outlets and it charges with more voltage than the camper does turning the battery switch on letting the shore power charge...how can this be?
The converter is a Progressive Dynamics pd4045ka.
It states that the output is 13.6 which is what is consistent with what my multimeter shows. When left on shore all day the batteries seem to max out at at 12.6
The tender is a Bailey Tender Plus that has the multimeter showing 14.7 while charging, and leaves the batteries at 12.8
I have left it on the batteries for roughly six hours, and where the batteries charged up to 12.8, the tender still din not go into maint mode, still blinking green signifying the batteries were still drawing, but at over 80%
