OPTIMA BLUETOP BT DC 5.5 batteries are dual-application deep cycle batteries.

They can be used for all applications related to servitude (nautical accessories, domestic applications, boat engines, bow thrusters) or for starting.

On the water, the engine that drives you must be able to bring you back… The OPTIMA® BLUETOP® battery delivers precisely the power you can trust. Its patented SPIRALCELL® technology means longer run time, faster recharging, and up to twice the lifespan of conventional marine batteries. Plus, it's designed specifically to meet the challenges of marine applications.

The advantages of the Optima BLUETOP range:

- Available models: for starting and for dual applications (starting and deep discharge)

- Lasts up to three times longer than other batteries.

- More power during the first second of cranking (as well as during the first 2, 5 and 10 seconds of cranking), compared to conventional lead-acid batteries of the same category.

- Consistent performance quality: your battery provides the same level of energy throughout the discharge.

- Ideal for seasonal use: once fully charged, the battery can remain unused for 12 months at room temperature (or lower temperatures) and will still be able to provide the power needed to start your boat's engine.

- Fifteen times more vibration resistant than other batteries.

- A leak-proof battery with complete mounting flexibility - can be mounted in almost any position.
