Hang on and pay attention.
If you deep discharged a battery that is not a true deep discharge, it may have shorted a cell, in that case, the PD4645 may be limiting the charge current to both protect itself and prevent a fire.
If you unplug from shore power, the terminal at the battery will probably drop fast. If it does, that battery is probably toast.
Disconnect the battery and then put your meter on the on the 12V buss anywhere. That should be good a good voltage. That means the converter is still good. (PDs are good, but should be checked anyway.)
If you chose to put a brute force charge on the battery, remove it from the unit first. If it has a shorted cell, things can go bad in a big hurry.
