Specs. Your not going to find a better suited battery to off-roading than Optima Yellow Top high performance battery, and batteries definitely take a beating. Conventional lead acid batteries are not designed to handle the extremes associated with going off-roading. The Optima Yellow Top battery is vibration resistant, spill-proof, maintenance free, and can provide premium cranking power and deep cycling power. Construction. Optima batteries are built tough, and when your off-roading you need parts and equipment that are strong enough to handle it. AGM batteries (Absorbent glass mat) charge up to 5 times faster and also stand up to cold weather better than conventional lead acid batteries meaning you are less likely to wind up with a dead battery when off-road during the winter. Application. This Optima Yellow Top Battery is designed to be used in all 1987-2011 Jeep Wranglers, including YJ, TJ and JK models.
