[C320-list] 4D batteries

[Jon Vez]

Kirk,

I have the same setup. The AH on the 4D's are rated at 200 each. I've had
mine for 5 seasons and they are still going strong. I have a Link monitor
and I've never run mine below 120 AH before a charge so I'm not sure how
much lower they will go. I am on a slip with shore power, but every season
we do a 2 week trip away from shore power with the stock 55 amp alternator
using fridge full time. I usually see between 30-55 AH's drawn in a 24 hour
period and I can replace these with 2-4 hours motoring--usually satisfied
while under way. 
You can run them completely down without ruining the batteries and they are
great for us in the North during winter layup. You don't have to top them up
and can store them on the boat. They are almost fully charged in the
Spring...
I believe the Lifeline brand will give you 205 or 210 each....

Regards,

Jon Vez

Thanks Chris, good information. Do you know  what the AmpHour spec is on
these batteries?

I replaced my OEM Exide Nautilus deep cycle 4-D's with their commercial
truck batteries at half the price. They no longer make the batteries with
the same specifications that they formerly provided Catalina in the Nautilus
line for OEM use. That battery had a significantly higher amp hour rating.
 A careful analysis of their battery specifications (which can be found on
their website) led me to conclude that the commercial truck battery is the
same battery as the ones they formerly provided Catalina. Same heavy plate
anti-shock construction as deep cycle marine batteries with more amp hours,
but automotive terminals.

Part number COM-4D-P
1000 cold crank amps @ 0 deg.
1200 cold crank amps @ 32 deg.
320 RC amp minutes @ 25 amps
