Need to Buy Solar Batteries? Need a better and more cost-effective alternative to Lithium Ion, Tesla Powerwall, or Aquion Saltwater Batteries? Looking for best cost, low prices, best performance, longest life span on deep cycle solar batteries?

 

50-60% less costly than Lithium batteries with 80% of the life expectancy, Firefly Carbon AGM batteries charge faster and have better hot and cold weather performance than Lithium batteries. And Firefly Carbon AGM batteries can't suddenly catch on fire or have thermal runaway issues like Lithium batteries.

What's the story on Firefly Batteries?

Firefly was born in the R&D laboratories of Caterpillar Inc., a well-regarded maker of heavy equipment. CAT is known world-wide for its high-quality equipment but even so, its customers often complained about battery lifespan, and about performance, particularly in hot/cold weather, so CAT set out to find a better solution. Invented in the Caterpillar R&D labs after several years of development and patented in 2005, the Firefly Carbon Foam AGM solar batteries are a unique American-invented technology providing extra-long life, high amp charge & discharge, outstanding PSOC (partial state of charge) performance, and outstanding performance in very hot or very cold weather.
 
In the real world, solar batteries are not always fully discharged and then fully recharged every day. PSOC operation is a more common solar usage and is another area where the Firefly Carbon AGM battery beats all others. Many solar battery manufacturers prefer to test and discuss cycle life based only on full discharge and recharge cycles. But in the world of off-grid solar, PSOC performance is another area where Firefly Carbon AGM excels in performance, beating all other AGM batteries by a wide margin.
