Batteries for winter storage

[jhhall]

I have a 2006 36 Sovran.  The batteries are difficult to get to.  They were new when I bought the boat 7 years ago.  All I do is turn the battery switches and all the 12v breakers off.  On my boat with the switches and breakers off all 12v is disconnected including the CO Detector, smoke alarm and electronics. I have not had to replace the batteries. I store heated.  Other Tiara owners in the building do the same thing with similar battery life results.
