Blue Top Deep Cycle
The constant vibration and shock forces caused by hitting the waves can shorten the life of most marine batteries, but not Optima. The patented SPIRALCELL eliminates shedding of the active paste material. High-purity lead grid. The Optima can sit for extended periods and still have sufficient power to start your boat engine, which means that the Optima is ready to go when you are! The Optima resists sulfation better than conventional batteries to keep the Optima's cranking power and capacity at peak levels. Completely sealed design. The Optima can be mounted in any location or orientation (even upside down) to provide you with a variety of flexible installation options.
