Batteries Discharging

I have a 2014 Class C Sunseeker Over the winter I left plugged in to shore power and batteries drained. I went out monthly to start generator and had to start up engine in order to do so, would not start up off batteries. While plugged in is the disconnect switch suppose to be ON or OFF

Disconnect switch should be in the on position. Check the water level in the batteries.

Your converter is overcharging the batteries causing the electrolyte to boil off leaving the batteries dry. If the battery is dry then you will need to replace it with a new one.
99% of the time when a battery is dried out it will no longer take a charge.

Just to be clear: are you saying that you had the disconnect in the ON position, AND that the batteries became low on water (DRY)?

If so, Boondocking is correct. Get new batteries and use only a battery Maintainer during the off-season.

Good one HERE: http://www.amazon.com/Schumacher-SP3.../dp/B00752TRP0

Actually Boondocking didn't say to use a maintainer, I would replace the converter since it clearly is overcharging the batteries and will continue to do so during the season when you use the RV. Fix it. A maintainer won't replace the converter and you still need a converter!

You are correct about my statement. Poor wording on my part.

I would not condemn the converter out of hand without testing it.
