fifth wheel battery

The 12 volt battery in our fifth wheel has been leaking water from the cells. The battery cell water is coming from the cell water cover. The fifth wheel has been parked for the past six months and is connected to our 110v house electrical outlet to keep the battery charged. The battery on/off switch is turned to off. I have kept the cell water level at the correct level. Do not know why the battery is pushing the battery water out. The coach battery level indicator shows the battery is fully charged. Is this a sign of a defective battery or might it be indicative of malfunctioning converter charging?
Thank you for your thoughts.

That's not "water", it's sulfuric acid and will corrode lots of stuff.
You need to wash down the area with a strong solution of baking soda and rinse it well.

As for the battery, sounds like it is being overcharged to me. Maybe disconnect it for awhile. Have you checked the voltages? (On and off charge).
Unfortunately it may be too late and it's toast!
The problem now is if you add water to top it up you will dilute the acid. To do it right needs the acid itself replenishing.
You could get it checked out at Auto-Zone (or similar) and they should be able to top up the acid if it is otherwise OK.
Good luck.
