"Blackmax" this is for you man since someone just sent me something about Optima Batteries which have one of the highest warranty rates of any battery out there. Believe me I've sold them for over 15 years, not worth the money. If you want my personal opinion, go ahead and go with a 800 cold cranking amp battery (whichever brand you choose) The cost difference between something in the 500-600 range and the 800 is usually less than 10$ and for the price of a lunch you know you will have more than enough. It's gonna be an overkill but say 2,3,4 years down the road when that battery on its best day is only operating at maybe 60-70% it should still be enough to start your motor.
Your brand you choose is your choice, I choose interstate however there are other companies out there that make good batteries. Just pick one you can afford with the best warranty and enjoy the time on the water.
