Reliability and, above all, a long service life. These are important criteria for a good battery, especially in the water sports sector, where a long recharge is not always guaranteed. The Optima® BlueTop works with the patented Spiralcell® technology, which guarantees a faster charging time and a doubling of the service life compared to conventional marine batteries. Leak-proof and maintenance-free, the sealed housing of the Optima® battery is very safe to handle.
