It's time for me to replace the battery on my GS4. At first the was going to get the Optima yellow top (deep cycle), but I just found out that Rockford Fosgate and Exide has introduced their own line of deep cycle batteries. The Technology seems to be the same, but the Fosgate battery has more cranking amps than Optima's (750A vs. 950A). I'm not that knowledgeble on the subject, I can use some advise.

I almost forgot, I can get the 2 batteries at about the same price.
