Hey guys? I was maybe thinking about getting an Optima marine, Blue Top battery for my E300 as my 2 year old Interstate is really getting weaker, leaving the domelight on this past summer for a week obviously didn't help it.

I was thinking the Blue top because:
1. More CCA than the Red Top
2. Can be deep-cycled
3. Available at Costco, which I'm going to in a few minutes...

When comparing the CCA on my current Interstate w/ the Blue Top they were virtually the same and the Optima is smaller and maintainence free with no need for a vent tube..

What you guys think?
