The 12V E31 battery developed by Firefly Energy maintains long life even under partial state of discharge operation. It has a throughput efficiency greater than 90% and improved high/low temperature performance. It provides superior protection against corrosion and sulfation related problems due to the implementation of Firefly’s Microcell Carbon Foam technology. With their disruptive technology, they offer 3-4 times the cycle life than conventional battery; 800+ cycle @ 100% DOD and 3600+ cycles @ 50% DOD; throughput efficiency > 93%; operation in partial state of charge for days without loss of capacity; high rate of charge @ 1C; excellent recovery from 100% depth of discharge; high shelf-life; highly Immune to corrosion and sulphation; superior performance in extreme climatic conditions (-4°F to 122°F: -20°C to 50°C); and capable of very high rate of discharge.
