HARLEYBOY,

I have been the route with batteries. Deka is a good battery. You can probably get them at NAPA. They, like anything else that's half way good are a little expensive. IMHO Interstate is a no no.

I personally like the maintenance free battery. I have had the best success with the Delco Voyager. They are a also a little expensive and hard to find. I got the last ones from an AC DELCO dealer. The Delco's that I currently have have been in the boat for 6 years and are still going strong. I have an on-board 3 bank charger to maintain them.
