12V 75Ah AGM Engine Starter Battery Optima Blue Top BT DC 5.5

Optima Blue Top BT DC - 5.5, 12V 75Ah cycle-proof battery especially for boats

The Optima Blue Top series lasts longer above water and with its seawater-proof poles is well suited for marine applications. Optima starter batteries combine the product features of several conventional starter batteries, such as high cold start performance and cycle stability in one product - under almost any condition.

The patented Spiral cell technology guarantees longer running times, faster charging and twice the life of conventional marine batteries, and the constant vibration and shock of the waves can be fatal for conventional marine batteries.
Optima batteries are twisted into a fixed spiral, preventing plate movement and resulting damage in harsh weather conditions, resulting in extended battery life.
These batteries are particularly suitable for marine applications where cycle or traction operation is required. The OPTIMA BT DC 5.5.BLUETOP is suitable for all deep-cycle applications (boat accessories, wheelhouse loads, electric motors, bow thrusters) and for launch applications.
