deep cycle marine battery help please

[jeremypeace]

I have a optima yellow top in my boat, It lasted a whole day without a alt charge, running a 140hp volvo with the radio playing, and the next morning it still had plenty of charge to start the boat after I discovered the missing alt belt. It was a spendy battery but I have had it for 5 years now and it still works like a champ. Little spendy but a good one.
