Battery on/off

When hooked to 50amp shore power for more than a month, I developed acid build-up on my house, wet batteries. Am I over charging and if so, what can I do about it? Thanks......

YES.............overcharging will cause boiling

What is being used to charge with....converter or inverter?
What Brand --Model and year is device?

More frequent check of battery water levels....topping off with distilled water as needed will help (especially if you don't check/maintain levels routinely)

So..........what do you have for charging ??? It could be failing

OR you just are letting water levels get too low to begin with\---bad cell in one of batteries will also cause excessive charging.
Have you checked specific gravity on each battery cell?

The output on most converters or inverters is adjustable. If your converter has only a single output level it should be about 13.5V but if multi stage charging is available it will be higher when charging but drop back into the 13.5v area when maintaining, assuming that you have flooded cell batteries.

A 2014 should have a smart 3 stage charger.

Do you fill the cells just below the rings in the holes ? If you go to or above them, they can flow over, causing your problem.

I have 2 batteries that I can't see in and overfill them. I see the the white acid stains on them and not on the others.
