We are working on a battery system which has the potential to make regular lead-acid batteries and AGM batteries a thing of the past, I hope. I am working on some prototype, dual power centers consisting of a starting source and a deep cycle source that are packaged together, yet independent and removable.
The prototype starting unit we are testing puts out 500-CCA and is 4.5"L x 4.5"W x 4.25"H and weighs 3.5-lbs! It has already been tested to crank a 250-HP E-TEC 23 times in a row before it died. It will not spill, can be mounted in any position, and does not have the thermal issues of standard lithium ion batteries. It also can handle short intense draws better than standard lithium ion batteries as well.
I am hoping this technology could help with small boats like Montauks, where all the batteries could be mounted inside the console and not take up much space at all. These batteries are about 1/10 the weight of a comparable lead acid batteries. Only downside of course will be cost.

WOA--seriously cool. My close friend is a battery engineer and a damn good one. Could help-- good luck

What's the AH capacity at 12 VDC? If' I'm just sitting there drowning worms with my sonar, radio, stereo, computer, and coffee maker running, how much time do I have?

Pete--I hope this works out. It would be nice to have an alternative to heavy batteries. The more stuff that can be hidden away in the console not only improves the weight distribution of the boat, but makes room for other things like gear.
Hoosier--You ask the million dollar question! The batteries I am currently about to test are the starting batteries. They put out some serious CCA for their size, but they don't have many Ah at all. They have about 13 Ah which won't run much for very long. But not to worry; the manufacturer says they can make a battery that also has a generous amount of Ah. So we would couple the two together in a case of some sort and you would have two independent batteries in one unit. The cool thing is, you wouldn't have to worry about your electronics draining your starting battery and not being able to go home after a good soak.
What do you guys think of a silicone case, kind of like an iPhone case, to hold the two batteries together? There could be some rigid plastic integrated into the case design to provide a mounting flange and maybe add some support. the reason I say silicone is it's soft and stretchy which allow you to remove one or both of the batteries and it would cradle them as well.
Fitment is really the biggest challenge to getting this right. Any ideas and suggestions would be greatly appreciated.

I think there is great potential in batteries.

Punny, JimH. Punny.

Dave--I am serious. In the current marketplace I see low resistance. Change will have to be inductive, if the consumer has the capacitance for it. There may be some reluctance among boaters. Dave, I charge you with the marketing plan. Boaters need someone to lead, a new product to rectify the problems of the past. I float this idea to you, but don't dwell on it. Discharge your duties!

What is the life expectancy of these batteries? I see great potential in the area of battery improvement as its really the one 'technology' holding a lot of other technologies back. What you describe sounds incredible.

The life expectancy of these batteries is twice as long as lead acid and they have a 3 year warranty. Another really cool feature that boat owners should appreciate is that they hold 90% of their charge even if not used for a year! As long as they are disconnected. It's time for something new and exciting to come up in the marine battery world. Boats from 30 years ago are still using the same batteries as today, which blows me away since there have been advances in just about everything else that goes into a modern boat.

Sounds too good to be true so it probably is. What chemical technology is used in these batteries ?

davej14- If I get to a point that I draw the conclusion that they are too good to be true, then I'll tell you the chemical technology. We'll just have to see what happens when I test them this season. Wish I could share all the details now, but there is too much to lose if it's the real deal and I spill all the beans just yet.
