Optima Bluetop BT DC 5.5

The Optima Blue Top series lasts longer in water and is well-suited for marine applications with its seawater-resistant poles. Optima starter batteries combine the features of several conventional starter batteries, such as high cold cranking performance and cycle stability, into one product—under nearly any condition. The patented spiral cell technology ensures longer run times, faster charging, and double the lifespan compared to traditional marine batteries. The constant vibrations and shocks from the waves can be fatal for conventional marine batteries.

Optima batteries are wound into a tight spiral, preventing plate movement and resulting damage in rough weather conditions. The result is an extended battery life. These batteries are specifically designed for marine applications where cycling or traction operation occurs. The Optima BT DC 5.5 Bluetop is suitable for all deep-cycle applications (boat accessories, helm loads, electric motors, bow thrusters) as well as for starting applications.
