A single battery can be drained within a few days from parasitic draws without converter constantly charging and providing 12 volt DC power when plugged into shorepower. There are fuses that can be checked, make sure converter is indeed receiving 120 volts AC when plugged in, check converter output for 13.2 volts DC or higher. If all is OK, somewhere along the path DC charging voltage is not reaching battery posts.
