Optima Blue Top BT DC - 4.2, 12V 55Ah, AGM cycle resistant, SPIRALCELL TECHNOLOGIE®


The Optima Blue Top series with its seawater resistant poles has been developed for marine applications. Thanks to the patented Spiral cell technology it can twist the power for a very long time Optima batteries are ready to turn into a fixed spiral, thereby avoiding plate movements and resulting damage in harsh weather conditions, resulting in an extended battery life.
These batteries are particularly suitable for marine applications where cycle or traction operation is required. The Optima BT DC 4.2 Bluetop is suitable for all deep-cycle applications (boat accessories, wheelhouse loads, electric motors, bow thrusters) and launch applications.
