To power the 4.0L engine, we dropped in a 34/78 series Optima RedTop battery. The Optima RedTop is a high-performance AGM dry-cell battery which, in this application, offers a stout 800 cold-cranking amps. While the company’s YellowTop line is best suited for running large-draw accessories, the RedTop starting-series battery is well suited for our Jeeps electrical needs. The spill-proof dry-cell battery can also be mounted in any position, though we chose to place ours in the stock battery location.
