DUAL PURPOSE Starter and Service BatteryThanks to SpiralCell Technology®, OPTIMA® combines the benefits of the starter battery with the performance of the service battery. In addition to delivering power longer, the OPTIMA® battery can also withstand more deep discharges and faster recharges than other technologies. So you can count on longer and more reliable operation of your accessories for more years. This makes OPTIMA® the best investment.Low self-discharge makes OPTIMA® batteries the ideal choice for seasonal use vehicles. During periods of detachment, OPTIMA® batteries retain significantly more power than conventional batteries (the battery must still be fully charged before a period of detachment).Internal components made of 99.99% pure lead allow OPTIMA® batteries to withstand a significantly greater number of charge and discharge cycles and continue to deliver a high percentage of total capacity. OPTIMA® batteries are ideal for vehicles equipped with multiple on-board electrical accessoriesthat remain in operation even when the engine is off.
