Optima Spiralcell batteries take AGM technology to a much higher level. Pound for pound Optima's performance beats the rest! Optima Spiralcell Key Facts:

At the heart of every Optima battery is a unique series of individual spiral-wound cells made up of two pure (99.99%) lead plates. These lead plates are coated with a precise coating of lead oxide. Each lead plate is manufactured as a continuous cast strip which helps to closely maintain critical thickness tolerances.

The two plates get a proprietary separator made from a micro-fibreglass blend similar to fine cotton. This separator performs two critical functions; it keeps the two plates from touching and it holds the electrolyte in a uniform suspension.

Critical tolerances, temperatures, humidity and automated processes are maintained and constantly monitored during the manufacturing process.

Optima batteries precision-moulded cylindrical cases are made to such tight tolerances that only virgin polypropylene can be used. This ensures perfect and uniform compression once the Spiralcell is inserted and also avoids any potential contaminants or impurities from pre-used plastic.

12 Volt Optima batteries contain 6 Spiralcell cells, each having a fully charged open circuit voltage of 2.2 volts for deep cycle batteries and just over 2.1 volts for starting batteries.
