(Inspiring music) - Hi, Jeff Cote from Pacific Yacht Systems here. Today we're gonna talk about Firefly batteries. Here's a Firefly battery. It comes in really two sizes, group 31 and L-15. And why is this battery so particulated, we're doing a video about it. Firefly batteries were invented for a need. And the need is that batteries overtime, left uncharged, or unattended or partially discharged sulfate, that means they die. They die prematurely. They age prematurely. So Caterpillar, basically invested in a lot of R and D to figure out a way to make sure that batteries would last longer. And they came in, and realized the battery that was invented called the Firefly battery. It's a Carbon foam AGM battery. And what's so amazing about this battery and there's so many different things that are amazing about this battery, it is really almost a miracle battery in terms of Lead acid technology. The first and foremost is that this battery can stay in a partial state of discharge. Meaning you can actually have that battery on your boat at 50%, 60%, 70%. And a year later, when you come and recharge the battery and you've left it in the discharge state, that battery is gonna actually come back and recharge back to 100%. So if you're wondering, what is its depth of discharge translate to? What does it mean to me as a boater? Well ultimately this depth of discharge means that you can actually have half the batteries. Meaning you need to buy six of these flooded group 31 batteries to have the equivalent in three AGM Firefly batteries. So you can either do two things, you can either save space and volume or if you have limited space and volume in your boat, and you want to double your battery capacity but don't have the space for it, putting these batteries on your boat will effectively double the usable battery capacity on your boat, because the 80% depth of discharge, comes out to be twice as much usable battery capacity as a flooded Lead acid conventional battery. So that's an incredible feature for boaters that are going off shore, boaters that are gonna be staying in a partial state of discharge, for extended period of time. And the battery will not age prematurely because of it. The other thing that's incredible about this battery, is the number of life cycles. Meaning, if you bring that battery down to 50% depth of discharge, like a standard flooded Lead acid battery, instead of giving you only maybe 300 cycles, this battery is gonna give you 3600 cycles. That's a factor of 12. I mean that's pretty revolutionary. And it's an AGM battery, which we all love. Maintenance free, there's no need to top off the liquids. Most battery chargers obviously are compatible for the last 15 years with AGM charge profiles. So really when you're looking at this battery and you're looking at the price point and yes it's more expensive than a flooded Lead acid battery, and more expensive than AGM. But when you consider the fact that it last 12 times longer, that it has a depth of discharge where you cannot use 80% of the battery and still get 1200 cycles. This is our number one seller of batteries by far here in the Pacific Northwest. We've installed hundreds upon hundreds and hundreds on these on boats. And if you've got any questions and wondering if the Firefly battery is right for you, contact us here at Pacific Yacht Systems, and we'll be glad to answer your questions. Thanks for watching.
