[C320-list] FW: Re: Are 6V Batteries Superior To 12V Batteries

[Karl Mielenhausen _/)]

Warren,



When I replaced each 4D with a pair of golf car batteries, I had to lenghten the Catalina battery trays by about 1.25". The battery height "barely" made it, in fact I had to dimple the compartment cover in 2 places for the forward battery.

I can't disagree with much that's been said.  However, I've not see the arguement on price and capacity.  I don't know why it is but I understand golf cart batteries have about 200 AH capacity.  Also, golf cart batteries can be found at Sam's Club, BJ's, and I presume CostCo for quite a bit less than equivalent 12V 4D from the likes of BoatUS.  Price of about $60 seems to ring a bell.<br><br>A number of people have replaced two 4Ds with four golf cart batteries.  Total amp hour capacity goes from about 270 to 400+ AH  for less money.  Unless there is a kickker, that sounds like a good deal.  Compare the dimensions of the golf carts vs 4Ds.  I understand they are a bit taller, but otherwise fit in the same horizontal space.<br><br>I chartered a 52' Tarten in BVI and the captain said he has 12 6V golf cart batteries on board because they are much less expensive to buy, weigh less (easier to install/remove,) and have more reserve capacity than equivalent marine deep-cycle 
batteries.<br><br>Warren & Pattie Updike<br>C320, #62, 1994, "Warr De Mar"<br>Frog Mortar Creek, Middle River<br>Chesapeake Bay<br>
