Firefly Carbon Foam BatteriesThe ONLY carbon foam battery on the market
What makes Firefly "game-changing" technology?
Unparalleled Resistance to Sulfation
Sulfation is what usually kills AGM batteries. The Oasis carbon foam AGM can operate or be stored at a partial state of charge for long periods of time without a loss in capacity.
Depths of Discharge to 80%-100% of rated capacity
This can be done without any permanent sulfation or loss of capacity
Superior Life Cycle
Firefly batteries are capable of 2-3X the number of deep discharge cycles than that of other lead acid batteries
What is carbon foam?
Firefly’s proprietary technology comprises a carbon foam based porous foam with thousands of open cells/pores.
Carbon foam structure redistributes the small separator reservoir of a conventional battery to the pores of the active foam battery plates themselves. This increases the efficiency of the lead-acid chemistry because each microcell has its full complement of sponge lead or lead dioxide and sulfuric acid electrolyte.
In carbon foam, the discrete microcells collectively make up a new type of electrolyte structure (3-D electrode, pictured on the left). This results in higher power, energy and cycle life, as well as greater energy delivery and faster recharge capabilities relative to a conventional lead-acid battery.
When compared to lead-acid chemistry, Firefly’s advanced battery technology increases the cycle life by a factor of two to three times, but it can be built for three-fifths the cost of other advanced material batteries.
How do Firefly batteries perform in the real world?
Watch this video by a live aboard family in the Pacific Northwest who upgraded to Firefly batteries in 2015. They reduced their generator run time from 2-3 hours/day down to running every other day. After a year and a half they reported that the batteries were still performing flawlessly.

Charge Characteristics by Coastal Climate Control
The experts at Coastal Climate Control put together this graph showing the difference in performance between Firefly and a slightly smaller sized, new, high-quality, marine AGM battery. The graph shows that the Firefly battery can accept a higher charge for longer and the current tapers more slowly than the competition.
