Description
SPIRALCELL technology offers many advantages and features that flat plate batteries do not have. Thanks to SPIRALCELL technology, OPTIMA® batteries provide more power and are designed to outperform other batteries available on the market
SPIRALCELL OPTIMA technology takes AGM batteries to a whole new level. Equal weight performance Marine batteries that deliver maximum starting power even after long periods of inactivity. Accept deep discharges, ideal for the operation of all equipment and accessories on board. Classic and screw terminals.

OPTIMA is unparalleled. Here are some facts about SPIRALCELL OPTIMA technology:

At the heart of each OPTIMA battery is a series of individual spirally wound cells consisting of two sheets of pure lead (99.99%), precisely wrapped in a layer of lead oxide. One plate is positive, the other negative.
Each lead plate is manufactured as a continuous cast strip, allowing for rigorous thickness tolerances.
Both plates are equipped with a proprietary separator (this key element is made using a mixture of glass microfibres, having the touch of cotton), which fulfills two essential functions: to prevent the two plates from touching each other and contain the electrolyte in homogeneous suspension.
The unique manufacturing process of spiral continuous lead plates requires much higher accuracy and is much more expensive than the construction of conventional flat plate AGM batteries. Customized automated cell winding machines are required to meet the strict tolerances required to ensure quality and performance.
Once completed, each SPIRALCELL looks exactly like a 'rolled cake'. Rigorous tolerances, temperatures, humidity and automated processes are kept constant and are under constant surveillance.
OPTIMA cylindrical housings are molded using precision technology, with tolerances so rigorous that only virgin polypropylene can be used. This ensures a perfect and uniform compression after the insertion of SPIRALCELL, and avoids the presence of pollutants or possible impurities from recycled plastic.
OPTIMA 12V batteries consist of six SPIRALCELL cells, each with fully charged 2.2V open circuit charge for deep cycle batteries, and slightly more than 2.1V for starter batteries.
OPTIMA has built more than 100 million individual spiral cells since the early 1990s. Only OPTIMA knows how to build spiral wound batteries with such premium quality and delivering such high performance.
