DO NOT GET THE YELLOW TOP!!!!!! get the RED TOP... the part # is SC34U its 1000ca,800cca the major difference is the yellow will only take up to a 5-10amp charge (as it is a true deep cycle battery even the yellow starting version) the red top is a true starting battery an will take 30+amps and will recycle a lot faster than the yellow..

most people think the yellow is the better battery but its only better if u plan on sitting in parking lots (engie off blasting music) or car shows all day.. then trickle charge the battery back to full when done (8hrs fyi)

agreed. But because i plan to do just that at the car shows i will be entering i opted for the yellow. I went with a yellow 27R as that was what optima recommended. But i did have to modify the plastic battery cover just a tad bit since the terminals are up front now and not near the firewall. Also picked up the optima battery charger and will be making a quick connect plug to charge the battery when at the car shows.
