but I am still surprised that the batteries haven't needed any water added after a year. I keep the motor home plugged in 24/7 at a rented storage garage.
I'd be really surprised too.....to the point of being somewhat skeptical.
The top of the plates likely will be "wet" even if they are not covered and that can be deceiving when checking.....especially if you can't see straight in with a light.
I think you need to figure out how to add some water.....soon.
P.S. When your batteries are difficult to access, that is just one more plus on the side of AGMs the next time they need to be replaced.
