Battery Guru's What is best set up?

[Alan06SUT]

Ok, my battery is starting to do funny things. I drove all day today no issues, then I pulled over to get a burrtio and when I came out it wouldn't start. We hooked up some cables to my buddies Explorer and it did nothing. He reved the motor and I hit the key, and it started without hesitation. Then I got home 5 min away, and it started fine again. All this time the radio, lights and everything else worked fine.

Anyway I hope its the battery. I want to go to a dual set up anyway since I have the warn multi mount winch, 12 accessory lights ( I use them very often almost daily), trailer brakes, etc.

I love optimas but according to many sources, they don't have one with the required 880 CCA's??WTF? I saw the yellow top with 900 CCA's but it dosent show as being the right battery for the H2??? And its a deep cycle rather than starting battery.

Should I do this battery X2 or do one red starting battery and one yellow deep cycle battery w/ an isolator? Or use a totally different set up?

TIA.
