Leaving batteries connected during long term camping

Gary,

It also depends upon the kind of batteries you have.

For instance, I've always used batteries in our 10 year old RV that are supposed to be stored ("floated") with around 13.6 volts on them. So, just about 24/7 this entire time I've left the stock 13.6 volt converter in the RV turned ON and the coach batteries hooked up to them. The type batteries I use not only float well on 13.6 volts, but when they're run down they also charge up fast enough on 13.6 volts.
