Moving on to the Absorbed Glass Mat batteries—specifically the spiral-cell AGM design that Optima uses—the science behind how they work is very similar, with a cathode, anode, electrolyte, and permeable separator.
Absorbed Glass Matte or "AGM" batteries are the latest and greatest in lead-acid batteries. An AGM battery uses a separator consisting of fiberglass between the plate and wrappers to hold the electrolyte in its place with capillary action.
Spiral cell technology, a subset of AGM) batteries, is a unique design using tested and true practices. The name ''spiral cell'' stems from the physical layout of the battery, where lead plates are meticulously wound into a spiral or coiled configuration.
The heart of OPTIMA® SPIRALCELL TECHNOLOGY is a series of individual spiral-wound cells composed of two pure (99.99%) lead plates coated in a precise coating of lead oxide. This breakthrough in battery design delivers more power and consistently outperforms conventional flat-plate batteries.

Starting and dual-purpose AGM high-performance batteries ideal for automotive applications. The OPTIMA® REDTOP® and YELLOWTOP® provide up to 15x more vibration resistance, 3x longer service life, flexibility for mounting and faster recharging.
Even though the Optima''s spiral cells take up as much as 15 percent more volume than a flat-cell battery of the same cold-cranking amperage (giving plate-based AGM batteries a theoretical
AGM batteries can come in several types of design, but these essentially condense down into two types: AGM flat plate and AGM spiral wound, where flat plate appears very similar in outlook to traditional flooded batteries while spiral wound looks quite different, as exemplified by Optima brand batteries.
A spiral cell battery layers the plates in a spiral layout, and the lead used is 99.99 percent pure, which leads to greater deep cycling over the life of the battery. An AGM battery also
12 Volt OPTIMA batteries are made of 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. OPTIMA has built over 100 million individual spiral cells since the early 1990''s.
