Firefly AGM Battery Testimonial - Nigel Calder
- Category: Battery
We now offer Firefly Oasis Group 31 battery with award-winning Firefly Microcell™ Technology with Carbon Foam plates to ensure longer battery life in deep discharge PSOC applications.
Nigel Calder tested this battery in real-world conditions. Here is what he thinks:
"In preliminary testing I worked the Firefly batteries hard in a real-world (onboard, while cruising off the west coast of Scotland) partial state of charge operation. The goal was to minimize engine run times and optimize electrical system performance in an 'off-the-grid' situation with limited recharging opportunities. The kind of operating regime I followed spells death for most lead-acid batteries. In contrast, after two months of intensive cycling, the Firefly batteries tested out with 100% of the capacity with which they started. These are encouraging results which, if substantiated over longer periods of time, represent a 'game changer' in terms of lead-acid technology and boat electrical systems design. I look forward to collecting more data."
Thermal Runaway in AGM Batteries

In Defense of Lithium Ion Batteries
Yes, it's true; thermal runaway can and does happen in Valve Regulated Lead Acid (VLRA) Absorbed Glass Mat (AGM) batteries, and is not a new phenomenon afflicting Lithium Ion batteries alone. A Google search of "Thermal Runaway in AGM Batteries" will reveal enough technical papers on the subject to keep even the most techno-savvy occupied for a long while, and will save me trying to explain the why's and wherefore's here. The simple fact is that, given the right conditions, an AGM battery can, and will, start a self-perpetuating internal heating process (thermal runaway) that can end in catastrophic failure with the possibility of fire and explosion. So why is there so much negative publicity and bad karma surrounding Lithium Ion batteries, when AGM's are prone to much the same maladies?
