I think I'm looking at new batteries.
I have a pair of interstate Costco 6v that are about 3 years old. We don't boondocks anymore and the trailer is at the ranch and hooked up constantly. PD9855 (?) does the charging. I did a SOC ...

9855 sounds like WFCO not the far better PD.
Let them sit disconnected and see if voltage holds up 12.65+ for a few days.
I would continue to use them until they develop other issues.
Memory is the second thing to go! I looked it up and it’s a PD9260C.
