What battery is everyone using

Looks like a group 24 to me. Bigger motor, more powerful version of a 24. Just about any group 24 should be plenty for a /6.
I have bought several duracell lead acid batteries lately from Sam's club. The duracell amg's dont have any more power, or longer warrantee than the lead acid wet cells.Two 78s for my pickup, two deep cycle 24s for my lift gate (one supposedly "new" interstate took a dump, was draining the other three batteries in the truck, a 27 for my Plymouth, and I have an old red top in the the car with the horrible battery access. New red top for that car when it needs one.
