What make of battery?
Does the maker have a charging profile?
AGM do need a "wake up" charge with higher voltage. Unless you can disconnect the fridge (disconnect, not just turn off), don't go above 15.4 volts. Best to totally isolate the battery bank when doing the reconditioning, then higher voltage can be used--but follow the battery maker's recommendations.

Thanks to all for the suggestions -- seems like conditioning is the right answer, I'll give that a go.
I do have a Victron charge controller with temperature compensation.
