Another thing that helps is an isolator. It will allow all batteries to be charged when the boat is running but will separate the starting battery when the boat is off so it is not drained.
Something like this:

A perko switch is fine but how many times do you forget to move it when you stop? With an isolator you don't have to remember.
Really you just have to determine how much amperage your devices are drawing which will tell you how many and how big of batteries you need to sustain that for the length of time you want.

Your point is well taken, though. It is something to consider.

Odyssey doesn’t make a distinction between cranking, deep cycle, or "house". If you go to their website and check the specs you will see they do both very well 
The difference between them and Interstate is the technology used. Their absorbed glass mat construction and quality materials used is the difference thus the price. Looking at the Deka website it looks like they have very similar technology (absorbed glass mat) and I would imagine a very comparable battery performance wise. I am unable to see the connection to Interstate though. Both websites claim different manufacturing in separate states from what I see. Not that it really matters. Bottom line is that I make no claims that Odyssey is the only choice as there are other good manufacturers out there. It’s just that I have experience with the Odyssey brand and they smoke the Interstates performance wise. From what is mentioned on this thread it looks like one cannot go wrong with either the Odyssey or Deka and I think it is great that both are made in the good ole USA

It appears they are not of same manufacture. They are distributed by the same company........ My bad!!!
Yes, my Deka is AGM and my Interstate starting battery is lead/acid. WHile my Interstate can run my stereo of a couple of hours, my Dekas blow it away as far as stereo goes. But the Interstate, cranks the boat better as it has more CCA. I have never used Odyssey Batteries, but I would assume technology is similar so I would expect them to perform similar to the Deka.
THe Optima is AGM as well, but it is too small to hold up to extended use (not enough reserve).

It is rather simple. For extended use (stereo), go with a dedicated AGM True Deep Cycle Battery such as Deka, Odyssey, or Kinetic. Not a dual purpose battery. The larger the reserve time the longer your battery will last, but the longer it will take to charge. In most cases as your reserve capacity increase so does the size and weight. Go with a dual purpose/starting battery to run and crank the boat.

I've been using the group 24 Duralast Dual Purpose Marine Batteries which are manufactured by Johnson Controls and sold by AutoZone for only $79.99 ea. I run the stereo, LED's & TV/DVD player quite a bit and have never had a problem starting. The reserve capacity on these batteries is listed at 140.
The Odyssey 34/PC1500 has a reserve capacity of 135 and a price tag of $278.18.
The Odyssey is probably a better battery, but the "reserve capacity" seems to be the all important number here for extended battery life from use of accessories, so the Duralast seems to be a pretty good value... You could buy three of them for the price of one Odyssey and still have enough money left over to fill the fridge on the boat with beer!
