I need some info for the Batteries in our 1973 Gas Coach.. When we
bought it, there were 2 WalMart Maxx 29 Deep Cycle Marine Batteries,
875 cranking amps & 675 cold cranking amps. One was installed in the
front battery compartment by the drivers seat
& one in the Gennie
Compartment. I installed another of the same "Up Front", and another
under the entry steps, in the places provided. These are all 12V units.
Now they are about ready to be replaced.
Question is: Replaced with what?
My Coach is stored in a Storage area without connections of any kind,
and all the batteries have the knife type disconnect switches.
Would several 6V type be better for my use? AND WHY???
Also, is a smaller size battery, (of same cranking amps) any different
from a physically much larger unit.. Will the larger one have
more "Innerds" and last longer between charges, or have a longer
battery life.??
Most of the camping will be with hookups, but occasionally we will
DryCamp for a couple of days.
