Optima BluetopMore cycles in maritime use
Developed for maritime applications such as boat accessories, electric motors, bow thrusters, it also supplies consumers in camping vehicles or buses and stores electricity from wind or solar power systems.
Our recommendations for all utility applications requiring a spill-proof battery, especially in maritime applications.
Features
Leak-proof
Because the electrolyte is bound in the glass fibre mat and the battery is tightly sealed and equipped with a safety valve, it is leak-proof.
Your advantage: This battery is suitable for use on water, e.g. for powering on-board equipment or navigation instruments on boats, or wherever a leak-proof battery is required.
Permanently stable power
This battery allows constant stable current to be drawn.
Your advantage: Particularly suitable for applications in continuous use rather than with highly fluctuating power peaks and troughs.
Fast charging
The tightly packed AGM battery with wound grids brings a lot of reaction surface in a small space. It can also be charged with a more powerful charger than a GEL or flooded battery.
Your advantage: Short standstill times between rides.
Characteristics
- For highest cycle requirements.
- Constant performance quality during the entire discharge process.
- Shorter charging time and twice the life of conventional boat batteries.
- Designed for maritime applications.
- Very resistant to vibration.
- Wet charged. Ready to use.
- Sealed maintenance-free. VRLA battery with gas recombination and safety valves, where refilling is neither possible nor necessary.
- Leak-proof. Can also be installed at an angle, as the electrolyte is absorbed in glass fibre mats and the battery is tightly sealed.

What is a Supply Battery?
Supply batteries must provide power for as long as possible for consumers that are not connected to the regular power grid or the starter battery. Either in mobile applications, e.g. camping or in island installations such as mountain huts, or in safety applications when the normal power grid fails or to compensate for so-called mains wipers. Depending on the application, they are charged with a charger from the mains or via smaller photovoltaic or wind power systems.
So not only do they have to supply power for a long time and then take it up again well, but they also have to cope well with changing current levels and voltages.
Supply batteries are cyclic batteries, i.e. they are designed to continuously deliver current up to a maximum depth of discharge of 80% when supplying electrical consumers and then to be fully recharged again. In contrast, a starter battery delivers a short, strong current surge for starting the engine and is recharged by the alternator while driving.
Maintenance and Care
Absolutely maintenance-free batteries are valve-regulated lead-acid batteries or VRLA batteries (VRLA = Valve Regulated Lead-Acid) that are sealed at the factory. Here, significantly less gas is produced than in wet batteries. The gas produced remains in the circuit of the battery due to gas recombination. As a result, these batteries lose significantly less liquid. They do not need to be topped up, and it is not even possible to do so, as they cannot be opened again without damage.
