I've got an SRT6 and I'm contemplating replacing the original battery before winter cold sets in. At a car show two weekends ago I met a Deka territory sales rep (Steve Sylvester). He claims the Deka batteries from EAST PENN manufacturing are excellent because they have less outgas and super quality control. Of course he is the salesman so I'm a bit skeptical.

The Deka website lists either PN 648MF or 9AGM48 for the crossfire.

My question is (finally he has a question): Do any Crossfire owners have experience with the Deka batteries OR opinions regarding Deka batteries in general? If you have a Deka in your Crossfire which specific model did you choose?
