As has been reported here, just about any battery from a reputable source will provide the required power needs for the Crossfire. You just need to decide on how much you want to spend, with the major factor being a conventional battery versus an AGM version. I for one can't see the cost benefit of buying an AGM battery. Like pizzaguy stated, you'll probably end up needing a new battery every 4-6 years; some get longer service based on driving habits and overall care. Does the average car owner spend the time & effort to keep their car's battery in tip-top condition - none on the block where I live, including me! I'm convinced "maintenance-free" batteries exist for this fact alone!

For the record, last year I installed a Super Start Extreme 48 H6, P/N 48EXT from O'Reilly's Auto Parts. Paid $192.79 for the battery. What was my criteria - O'Reilly's was closest to my house, battery was in stock, price was under $200, ordered online, picked up in store 15 minutes later, Crossfire ready to roll 20 minutes later (I'm a little older now)! It doesn't get much better than that!
