if battery is ok, get a digital volt meter aka multimeter and check the voltage from the converter when plugged in
EVERY owner of an RV needs a voltmeter.
They can be had for $10 or less.

There are literally thousands of post on here about battery use and care.
Quick summary:
When fully charged and no load applied, it should read at least 12.6 volts. Then sitting disconnected for 24 hours, it still should read at least 12.6. If the voltage drops off when disconnected.....it's bad.
When connected to a charger, it should read at least 13.6 volts......unless maybe the battery was TOTALLY DEAD and the charger is small.
But in this case, of the PO not ever hooking up the battery, you can probably safely assume that it's bad. You could check the water level and then connect it to an outboard automatic charger for about a week but that probably would just be a waste of time. Even if it came back up to voltage, it probably wouldn't come close to being reliable.
