For 2012 the JK switched from a Group 34 battery to a Group 91 battery with the spec of 600 cranking amps (CA) and 475 cold cranking amps (CCA), but we swapped our stocker out with a Group D34/77 dual-post Optima YellowTop with 870 CA and 700 CCA. We prefer the YellowTop for high draw applications because it is a deep cycle battery, yet has enough power to be an everyday starting battery.
