Bill,
you say 10 years - how are you so sure it will hold?
These batteries are not as heat sensitive as lead acid or other battery technologies. If they don't work for ten years, you get that fraction of your money back.
These are really high quality state-of-the-art batteries.
I came out with LED position lights before anyone else did. They work great, pass FAA specs, and are less expensive, (still,) than anyone else's. I plan to the same sort of thing with batteries. Other folks will be selling batteries like these later, but, if enough folks are interested, you will be able to get them from me first, for less than others will charge later.
In about a month or so I'll "let the cat out of the bag" and reveal the manufacturer and the details. For now, I'm just trying to figure out if it is worth my time to develop a product.

I am living in a hot/humid country - I need a new car battery every 2 years,
like clockwork - sealed/no-maintenance battery.
In the "old world" (Central-Europe) a regular car battery would last at
least 4-5 years (no I have no comparrison, as back then ALL batteries where
"maintenance" batteries - however keeping the liquid level with distilled
water was all that was needed)
I just changed the bat again - from first sign (slight hesitation at start)
to "death" was 2 days...
At a rate of 40.- per battery I probably keep changing them, but I guess for
"weight-fanatics" it seems a cheap way to loose some.
I am just a bit sceptic on the 10 years.
Someonoe asked already - what's the tech behind this? In laymans terms
please :))
Great website!!
