You need to diagnose whether this is a battery with a bad cell. That is where to start.
Use a hydrometer to recheck both batteries. With batteries fully charged and charger turned off, check SG. If OK (no bad cells) then the next thing to check is the voltage your converter or charger is putting out. Some are adjustable, some are not.
If the charger is not adjustable in terms of output voltage, an inexpensive alternative while in storage and plugged into shore power is to by a HD 120 VAC timer (20 amp) from any box store. Plug your converter into it and let it run for 20 minutes a day. That should certainly keep up with the self discharge rate.
