If that modern converter is a WFCO all bets are off. Measure the voltage after a week and see if you actually see storage mode at 13.2 volts.
Regardless you still need to check the water level periodically.
See, that was my worry. It's a two hour round trip (during good weather) to my storage so the chances of me going during the next few months are pretty much nill. I think I'll pick up a timer and just set it to go for an hour or two a day which should be plenty to keep up with the small parasitic loss from the CO/LP detector and the stereo (or should I pull the stereo fuse?).
Hello Andy. Use your battery disconnect switch and you won't have to worry about parasitic loads while storing your rv.

If you are concerned about overcharging, buy a cheap mechanical lamp timer and install it between the power source and the charger. Set it to run for a couple hours per day.
Next time you are shopping for a house battery make sure to get a TRUE deep discharge battery. Most "marine" batteries are dual purpose and therefore are a compromise between starting and powering things.

Would a mid 90's converter be an "older" one?

It is the older converters that do not have a three stage charging cycle that are hard on batteries. The continuous charge on older units can boil the battery dry if not checked on regularly as far as I understand.

I have indoor climate controlled storage with power available. My question is how bad will a modern 3 stage converter really be to a marine battery over that period of time. Do I really need to go out and buy a charger that costs half as much as a new battery ...
