Endurance An Issue?

Optima blue top AGM batteries and AGM deep cycle batteries will keep you on the water longer. Spiral cell design of an Optima marine AGM battery with its tightly wound cells pressed into tubes, make them 15 times more resilient to vibration. Most important when you are pounding through the waves.

Our Optima marine AGM deep cycle batteries make also great start batteries also; they range from 750CCA – 900CCA. Optima marine AGM batteries and Optima marine AGM Deep cycle batteries are Spill proof they can be mounted on their side, have no terminal corrosion and do not gas under charge.

Features Benefits
Safety, on any Angle Traditional Batteries will spill acid after a rotation of 45-degrees. Optima batteries can be rotated up to 180-degrees with no acid spill.
Corrosion Free Terminals Optima’s unique approach to cell construction and fully spill proof design ensures zero maintenance is required and that corrosion does not form on the positive and negative terminals.
High Purity Lead Grids & AGM Separators Glass separator hold the electrolyte like a sponge immobilizing the internal components of the battery. This enables Optima batteries to deliver more power for longer, and over more cycles, than other AGM type alternatives.
Resealable Pressure Relief Valves Advanced pressure relief valves allow the battery to vent under extreme conditions, but remain sealed under general use. This resealable valve design dramatically extends the service life of the battery while minimising the risk of explosion during severe overcharge or discharge, and under other adverse conditions.
Repetitive Reserve Capacity Optima batteries have the ability to withstand significantly more discharge/recharge cycles with lower degradation of overall capacity over time than other AGM battery alternatives. This means more running time, faster recharge, and up to twice the life of traditional Marine and RV batteries.
Massive Starting Current Optima spiral cells have more surface area per cell than any other lead acid battery design and are linked together with huge heavy duty cast-on buss bars. This allows Optima batteries to deliver a higher level of power to the starter in the critical first 10 seconds of the vehicle starting cycle.
15 Times More Vibration Resistance Optima’s Patented Spiral Cell construction delivers more than 15 times the vibration resistance of a traditional lead acid battery. This all but eliminates the possibility of damage from vibration, which is a leading cause of battery failure.

In the off season conventional batteries sulphate in 3-6 months, which is leads to premature failure. An Optima marine AGM battery or Optima Marine AGM Deep cycle battery will retain its charge for 12 months (providing zero current draw), so it is already to go for the next marine season.

Emergency services such as the Water police and some Naval departments use the Optima AGM batteries for their boats, because reliability and performance is the key.
