Electromaax is an official regional dealer of Firefly’s award-winning and patented Carbon Foam AGM batteries. These carbon foam AGM batteries remove most of the limitations of current lead-acid batteries and much of the lead in the traditional batteries can be replaced with a new type of grid material called carbon foam.
These Firefly AGM batteries resist sulfation and corrosion and substantially increase the surface area of the battery plates.

Below are some of the main highlights of the Firefly Oasis – Group 31 – Carbon Foam AGM battery.
The Firefly Oasis utilizes a microcellular carbon foam grid which is imbedded directly onto the internal negative plates which helps prevent large sulfate crystals from forming. This sulfate dissolves back into the electrolyte after a full charge. For a full capacity recovery, equalization is not required and you only need to do a full recharge as needed to open up the full capacity once again. Also, there will be no permanent damage or capacity loss after extended PSOC operation, or from a deep discharge to a low SOC.
The graph below shows the difference in performance between Firefly and a conventional marine AGM battery.
The Oasis high C/10 capacity causes it is classified in the same category as batteries that are twice it’s size. The Oasis doubles the number of cycles of the best competitor in this group of BCI Group 31 batteries.
Firefly batteries can operate in a partial state of charge for very long periods of time without any degrade, however, the usable capacity will decrease with each cycle, when operating in this way. To regain the full original capacity, the manufacturer suggests it is necessary to perform a restoration “equalization” charge once or twice a week. We have a simple solution in our Emaax Pro regulator that enables you to do this from your laptop.
