Two versions, one result: Always the right choice for use in the boat sector - these are the "OPTIMA BlueTop" batteries. Either powerful starter batteries, which deliver optimal starting power even when the engine is damp or the battery is used for a longer period of time, or as traction batteries, which also supply the entire electrical equipment, even after a long break from the season.

Product feature and resulting benefits:

» Closed system = absolutely maintenance-free
» Cells wound under higher pressure = vibration resistance
» Uniform pressure over the entire plate = cycle stability
» Grid made of pure lead = good shelf life, high corrosion resistance
» No free electrolyte = no acid leakage, position independence
» Low internal resistance due to more active area = 3 x faster charging
» SpiralCell technology = All advantages of all technologies combined in one battery
» No dangerous goods = therefore also to be sent by post or parcel service
» All batteries with standard poles and additional threaded pins with wing nuts
