Optima Battery has taken the clean, reliable, high-power output that made the Optima REDTOP^® starting battery famous and engineered in DEEP CYCLE ability. The Optima, YELLOWTOP®, Deep Cycle battery uses the same unique SPIRALCELL Technology that outperforms and outlasts conventional flat plate batteries. The Optima YELLOWTOP® battery utilizes the same elements that Optima designs into the REDTOP® Starting battery. Optima Battery engineers then increased the battery plate density. This design gives the Optima YELLOWTOP® Deep Cycle battery the ability to be deeply discharged and recharged without giving up the famous Optima Battery high starting ability.

• Optima, YELLOWTOP^®, Deep Cycle Batteries provide high power output resulting in greater cranking ability at high current loads.
• Optima, YELLOWTOP^®, Deep Cycle Batteries are fully rechargable in as little as one hour.
• Optima, YELLOWTOP^®, Deep Cycle Batteries have been verified in Life Cycle testing to exceed 350 complete discharges.
• Optima, YELLOWTOP^®, Deep Cycle Batteries won't spill, leak, or corrode.
• Optima, YELLOWTOP^®, Deep Cycle Batteries can be mounted in any position - sideways, or even upside down.
• Optima, YELLOWTOP^®, Deep Cycle Batteries last two to three times longer than conventional batteries. Optima Battery engineers have used high purity lead design provides a much longer shelf life, meaning the Optima, YELLOWTOP®, Deep Cycle battery can sit unused for up to one year and still start your vehicle.
