You stated that you added 1/2 to 3/4 cup of water per cell. Was the level below the top of the plates on any of the cells? Plates that have the level expose them will dry and flake when water is added. Those flakes can build up in the bottom of the Battery and short out plate there by ruining the Battery. It is called a Sulfated Battery. It is always best to be sure the water level is above the plates.
By the way I have a hint for folks out there. Rather then the squeeze bulb or turkey baster to fill my batteries I use a pump up sprayer. Fill the sprayer, pump it up and then all you need to do is fill without a bucket and bulb. All you need to do the the sprayer is remove the tip of the tube.

I would fill the batteries and then charge until it goes to float and then store it.
I do have an inverter/charger, but this does not operate when the coach is in storage.

I have changed to caps with floats and have a gallon of distilled water higher than the batteries. When the level indicator says the water is low I just open the valve until they are full. A lot easier and quicker.

When you add distilled water you are not changing the makeup of the electrolyte but replacing the water that has evaporated. A charged battery shouldn't freeze.
I could be wrong but I think that anytime you top up your batteries, you should always use distilled water and you should always charge the batteries. When you are adding that much water I'm betting your batteries have been weakened quite a bit. If it was a minus temperature you would risk the acid strength being low enough that the batteries could freeze. Good luck, smokeater75

It sounds like I do need to recharge my batteries after adding water.

Lots of different maintenance free batteries out there.
I have use Lifeline AGM batteries for many many years in both sail boats and my RV's with excellent results.
About the only recommendation (and actually not that different from any type of battery) is that you have a "smart" charger or inverter/charger AND that it is properly programmed for the batteries you choose.
