Three years ago I installed two Firefly batteries on my Willard 30. So far
so good. I am wondering if anyone on the list has used Fireflies for much
longer times, eg 8-10 years and can report on their performance over a long
term.

Hi Richard,
Not sure they've been around 8 or 10 years yes, but if they have certainly
not many installed in boats. That said, I've been installing them for 3 or 4
years, and have installed somewhere between 80 and 100 as of now. I got one
bad batch (12) a couple of years ago and installed them on two boats. All
failed by just losing capacity at about the same time. Both boats, both with
solar and large inverter systems (one Victron and one Magnum) failed with
almost identical symtoms. Firefly replaced all with no issues after I
provided serial numbers. I suspect it was a known problem. I've done
anything from a small 2 battery bank up to a few boats with 10 of the 31's.
The rest are mostly on cruising boats out there doing it. I keep in touch
with many of these customers and all report good performance and are very
happy with the batteries. I jokingly call them a "poor man's Lithium".
Hope that helps some!
Discalimer: I do have a marine service company in Texas specializing in
electrical systems and am a dealer for Firefly as well as many other brands.
