The Blue Tops have CCA ratings from 750 to 900 which is plenty to fire up most outboards.

Optima marine battery manual#
It is wise to consult your owner’s manual for exact requirements of your outboard. Optimal Starting Powerįor most freshwater fishing boat applications, 800 CCA is plenty for starting outboards. The SAE stud is convenient for attaching a charger, and the threaded studs are great for permanent attachment to the power and charger cables in your boat. Dual Studsīlue Tops feature both dual SAE studs and threaded 5/16″ studs. This allows mount the battery in virtually any position you prefer, which is helpful in cramped boat compartments. Mountable in Virtually any Positionīeing completely sealed and fully self-contained, there are no openings or reservoirs through which the battery can lose its acid. The sealed AGM design is inherently vibration resistant, but the Blue Tops feature the SpiralCell technology with broad plate area that yields significantly better resistance to shock and vibration. This is a key benefit for frequent boaters and anglers who discharge their batteries on a daily or weekly basis. The Optima Blue Top 34M model has been cycle tested to as many as 350 discharges, which is about 2-3 times the lifespan of regular marine batteries. The Optima Blues consistently live up to their reputation for having an extraordinarily long battery life expectancy, provided they are charged properly. Optima batteries utilize 99% virgin lead plates, resulting in a lower weight battery of equal capacity. This unique battery design generates more power, consistently outperforming batteries with traditional flat-plate designs. Each plate is precision-coated with lead oxide.
Optima marine battery series#
Optima’s state-of-the-art Spiral Cell Technology consists of a configuration of spiral-wound cells, with each in the series made of two 99.99% pure lead plates. This generates higher efficiency of discharging and recharging. The AGM design retains the electrolyte in a state of suspension while simultaneously keeping in contact with the plates’ active lead material. With a traditional battery, electrolyte fluid levels must be maintained by checking and refilling as necessary to prevent battery from failing and to prolong the life of the battery. Optima’s sealed absorbed glass mat (AGM) batteries do not degrade or spill the way conventional flooded batteries notoriously do. The durability (shock resistance) and exceptional longevity (when best charging practices are used) make a BlueTop battery an excellent value and an extremely popular choice for long-time anglers and boaters. Optima Blue Top batteries are priced higher than some other marine batteries, but Optima’s advanced technology has resulted in a battery design of uniquely high performance and convenience. In this Blue Top marine battery review, we’ll cover all information you need to become familiar with Optima Blue Top features, as well as considerations in determining whether this is the right battery for your specific boat and purposes, and if they are worth the high price tag. Optima Blue Top is a well-known brand of premium marine AGM batteries (recognizable by their distinctive looks), and very popular among anglers and experienced boaters alike.
