I have a big very heavy Sears Marine deep cycle 12 volt battery (like
the kind used in motorhomes and such like) I bought at the local Sears
store about six years ago.Those kinds of batteries (deep cycle
batteries) shouldn't be drawn down to more than about half capacity,or
so I once read in an article.With proper care and maintnance,deep cycle
marine grade batteries should last ten to twelve years or more.

Yes... I have a similar Sears Deep-Cycle battery. My battery is in one of
those plastic marine battery boxes (Battery Box for Group 24 Size Battery)
and I mounted a five position RigRunner on the top cover (RIGrunner Model
4005): http://www.westmountainradio.com/order_us48a.htm I use PowerPole
connectors for everything.

My battery is under constant maintenance charge from a little battery
charger I built specifically for the purpose. Automatic battery chargers
are also available that allow a constant maintenance charge to be applied to
the battery for unlimited duration without damage to the battery.
