My boat's stored away from me right now, so I can't really look
and see what size I have or CCA. I don't recall it being anything
special. If I find out, I'll let you know. You should get the same
CCA as if you were getting a straight starting battery. If you see
MCA (maring cranking amps) deduct about 20% to get to CCA. With
your V8, you should probably get a group 27 if it fits in your
space.

Akeel, that's exactly what i do, inland lakes, bays, no ocean

outings... I plan on going that route, i have a jump starter
that i
bring out all the time, just in case. so I'll go with a deep
cycle
starting battery. THat interstate that hte other guy posted is
sufficent? Interstate SRM-24 Deep Cycle/Cranking. What do you
use?

Thanks again... Also what is a good sufficient CCA for a deep
cycle/cranking?

Sure, everyone will tell you, you need more back-up systems
than a
nuclear power plant, but here's a real world practical solution
that
balances safety with cost and space considerations. I have a
similar
size size boat with the same sort of electronics. I'm guessing
from
your boat and equipment that you use your boat for day time
outings
mostly on inland lakes or close to shore. I stick to the lakes.
I got
one of those combo starting batteries; half starting battery,
half
deep cycle. It works great and is going on four seasons.
Nevertheless, I did want a back-up. However, there really was
no room
or good place on my boat for a second battery. Given where I
boat,
there was little danger of a dead battery situation becoming
life
threatening. But still could be a major headache. I bought one
of
those portable jump start batteries and stowed it under a bow
seat.
They're like Frosted Flakes, they're greeeeeat! I thought there
might
be a problem holding the charge over long periods, but they
don't
even seem to lose their charge over a year or more (I top it
off
every more than that just to make sure, but one time I forgot
and
there still was a full charge.) I had to use it once because
like a
dummy, I drained my regular battery. I thought there couldn't
be much
kick in the relatively small battery, but the engine cranked as
fast
as always and started right up. Best $50 I ever spent.

You can start with a deep-cycle battery, adequately rated,
without
damaging the battery. You cannot deeply discharge a starting
battery and say the same.

It does matter if you get a deep cycle battery. It doesn't
matter
if you get a "starting" duty battery, provided you ave the
amperage
to do the job. (That should not be interpreted to read that
you
don't need a dedicated battery for starting purposes).

Just bought two of the Interstate batteries below for $70 each at the marina:

Warranty
BCI Grp # Interstate Type *CCA **MCA RC Warranty
24M 24M-XHD 800 1000 135 24

Dimensions (in.)
L | W | H Weight Terminal
11 x 6-7/8 x 9-1/2 48 Auto/Stud posts


My last Interstates lasted 7 seasons. I take them out every winter, bring them
home, and keep them charged.
