Battery Optima Blue Top BT DC 4.2 5.0 5.5

DUAL PURPOSE battery for starting and services

Thanks to SpiralCell Technology®, OPTIMA® combines the advantages of the starter battery with the performance of the service battery. In addition to delivering energy for longer, the OPTIMA® battery is also able to withstand a greater number of deep discharges and faster recharges than other technologies. So you can count on longer and more reliable operation of your accessories for several years. This makes OPTIMA® the best investment. The low self-discharge makes OPTIMA® batteries the ideal choice for seasonal vehicles. During parking periods, OPTIMA® batteries retain significantly more power than traditional batteries (however, the battery must be fully charged before a parking period). The internal components made of 99.99% pure lead allow OPTIMA® batteries to withstand a significantly greater number of charge and discharge cycles and to continue to deliver a high percentage of the total capacity. OPTIMA® batteries are ideal for vehicles equipped with multiple on-board electrical accessories that remain in operation even with the engine off.
