Optima Battery has taken the clean, reliable, high-power output that made the OPTIMA Red Top starting battery famous and engineered in DEEP CYCLE ability. The OPTIMA BATTERY Yellow Top Deep Cycle uses the same unique SPIRALCELL Technology that outperforms and outlasts conventional flat plate batteries. The OPTIMA BATTERY design uses the same elements that Optima used to make the Red Top Starting battery. Then Optima Battery engineers then increased the battery plate density. This design gives the OPTIMA BATTERY YELLOW TOP the ability to be deeply discharged and recharged without giving up the famous Optima Battery high starting ability.

• THE YELLOW TOP OPTIMA BATTERY provides high power output resulting in greater cranking ability at high current loads.

• THE YELLOW TOP OPTIMA BATTERY is fully recharge in as little as one hour.

• THE YELLOW TOP OPTIMA BATTERY has been verified in Life Cycle testing to exceed 350 complete discharges.

• THE YELLOW TOP OPTIMA BATTERY won't spill, leak, or corrode. THE YELLOW TOP OPTIMA BATTERY can be mounted in any position - sideways, or even upside down.

• THE YELLOW TOP OPTIMA BATTERY lasts 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 YELLOW TOP OPTIMA BATTERY can sit unused for up to one year and still start your vehicle.
