Optima

Optima Batteries produces AGM spiral-cell batteries that have become a popular upgrade choice for Jeep builds with power demands that exceed what a standard flooded-lead-acid battery can reliably handle. Their RedTop battery is optimized for high cranking amps and rapid recharge, making it a strong choice for Wranglers with upgraded starter loads, winches, and the frequent short-run cycling that trail use creates. The YellowTop deep-cycle AGM battery is designed for vehicles running substantial accessory loads, including lights, audio systems, compressors, and refrigerators, where the battery must handle sustained discharge and recovery cycles. Both products are built in a sealed, vibration-resistant case that holds up better than standard batteries when a Wrangler is subjected to the chassis flex and impact loads that rock crawling produces. Optima batteries are available in Group 34 and Group 35 sizes that fit Wrangler JL, JK, and TJ battery trays. Browse the full Optima lineup at BlackDogMods.
