The beauty of Firefly’s technology is that it brings an existing one to a whole new level of performance, breathing new life and power into proven lead acid chemistry and creating a whole new category of battery in the process.
Batteries made using the patented Microcell™ technology are ideally suited for deep cycling application where they operate in partial state of charge most of the time. Firefly batteries last around 2.5 to 3 times longer than the conventional lead acid batteries, which use lead grids.
