I just checked the fluid level in them and its right at the top. I admit, I haven't done any maintenance on the battery. I didn't realize you couldn't leave it hooked up with the shore power on. I figured that would keep it charged. Live and learn.
Proper fluid level is 1/8 to 1/4 inch below the bottom of the filler tube (Small air gap)
I leave mine plugged in full time, but I have a Progressive Dynamics 9180 WITH optional wizard, there is no better charger. I need to water them perhaps once a year when new.
SOME converters are well known battery killers.
So it depends on the converter.
