T&T: Deep Cycle Battery Woes

[Greg Bradley]

All - 

My wife and I left on our boat about a week ago and are slowing working
our way down the Tenn-Tom.  We just arrived at Pickwick lake and I
checked the batteries again.  I'm a little concerned about one of my
batteries.

I have 6 group 31 batteries cabled together as my house bank.  The
stickers on the batteries show they were new around Jan-Mar 2003.  I
heard that you could get at least a good 7 years from deep cycle
batteries, so I've been reluctant to replace them, but I am thinking I
need to now.

I have one battery that is hot to the touch and boils water out of it
in less than a week.  It's in the middle of the bank and is the only
battery that shows a little corrosion around the terminals.  I realize
this is not a good situation but I'm trying to understand it and I'm
curious to know if it is an immediate safety issue.  The other
batteries are fine.  

Thanks...
Greg...
