Optima's anatomy is built on Spiral Cell Technology. Unlike flat plates used in ordinary batteries, Optima uses two thin lead plates wound into a Spiral Cell with a glass-mat between to contain the acid. The technique of winding the cells, which are linked with solid connections gives maximum performance with a minimum size and weight. This makes Optima batteries compact, robust and easy to mount.
