TheOptima battery Bluetopis the ideal battery for water activities. With a strong vibration resistance, low discharge rate and therefore particularly recommended for seasonal use, it will be your best ally for your exits at sea.
It offers more power during the first second start (and for the 2, 5 and 10 seconds of the starting) than conventional lead-acid batteries of the same class.
With extremely low self-discharge rate, it allows starting the engine without any constraint even after an extended shutdown period. It provides the same energy level throughout the discharge.
100% waterproof, it does not leak and can be mounted in virtually any position.
Ready for immediate use, the Optima batteries last three times longer than conventional batteries and offer vibration resistance up to 15 times higher thanks to its reinforced anti-vibration internal protection.
These batteries are equipped with SpiralCell technology that is at the heartthe battery is a row of individual cells spirally wound and consisting of two pure lead plates (99.99%), wrapped with precision in a lead oxide layer. A plate is positive, the other negative.
Through SpiralCell technology, OPTIMA batteries provide more power and are designed to exceed performance in other batteries available in the market.
With its rechargeable capability, it is exceptionally fast and allows rapid recovery of power through short walk cycles.
Ideal for seasonal use: once fully charged, the battery can sit unused for 12 months at room temperature (or temperatures below) and will be even able to start the vehicle.
