Developed by scientists at Fire�y Energy, Microcell Carbon Foam is a material that's revolutionizing the battery industry. Compared to lead plates, one of the main components of all lead acid batteries, carbon foam delivers longer service life, increased energy ef�ciency and better performance under extreme conditions. That's why we used it to create our revolutionary Fire�y MCF battery.

Fire�y carbon foam design resists sulfation and corrosion (two of the primary causes of failure in lead acid batteries), while dramatically increasing the surface area within the battery, resulting in greater energy capacity, faster recharges, and deeper discharge capability.
