Terryandkim,
After purchasing our first trailer I would leave the 12 volt battery on the unit 365 days a year. It died in less than 3 years. I replaced it with 2-6 volt batteries. During the winter and extended non use, I would store them in the garage hooked up to a "BATTERY TENDER". 7 years later when we traded up, the batteries were still in good working order.
The new rig has 2-12 volt batteries. I still bring them home and put them on the charger to prolong their life.
With newer 3 stage converters there IS NO REASON to remove your batteries at all. Pretty much any trailer built AFTER the 1990s WILL have a 3 stage converter.
3 stage converters have a STORAGE mode which drops the output voltage to 13.2V. The converter can adjust the voltage output if there is a load and when no 12V load.. When there is no large current demand the converter drops to storage mode and at that voltage there is very little chance of boiling the batteries dry.
The bigger the battery bank in capacity the less likely you will boil the batteries dry.
I have a PD9160 with the three stage charge wizard pendant and one pair of 6V GC batts. I keep my converter powered 24/7 when not camping. The first 5 yrs on those batteries I did not need to add any water. As the batteries have aged I am adding only 5-6 oz per cell PER YEAR.. And so far the batteries are 10 yrs old.
The OP can post the make and model of converter they have and someone will be able to enlighten them on how the converter works and if it will be fine to leave powered up 24/7.
