I am definitely going to start checking the water level in them much more frequently. I never had this problem in the past with all the rigs I have owned but this one has more slides and is self leveling plus it has an inverter for a residential fridge. So there is a lot of new things or more of the the "old" things (slides).
If you haven't already bought a replacement, consider getting two true deep cycle 6V batteries. They will handle higher currents without being damaged, have more capacity and so on. You still have to check water levels a few times a year, but they are a more robust battery with thicker plates.
