Optima Bluetop BT DC 4.2

The Optima Blue Top series has been developed with seawater-resistant poles for marine use. Thanks to the patented Spiralcell technology, it can provide power for an extended period. Optima batteries are wound into a tight spiral, which prevents plate movement and resulting damage in harsh weather conditions. The result is an extended battery life. These batteries are specifically designed for applications in the marine sector where cycling or traction operation occurs. The Optima BT DC 4.2 Bluetop is suitable for all deep-cycle applications (boat accessories, helm loads, electric motors, bow thrusters) as well as for starting applications.
