Steve,
I think you are talking about the Odyssey "Dry Cell" battery series? If so, they
technology they use is "absorbed glass mat." The Odyssey folks call them "Dry
Cell" because if you were to break open the case, no electrolyte would run
out. It is totally contained within the glass mat material.
So, yes, a bit of advertising hype. But it is still an excellent battery. I have
an Odyssey 680 in my (under construction) Europa. The battery is 5 years
old. I've been using it to test the panel as it was installed. There were periods
as long as a year and a half where the battery sat unused. It held a charge
for those unused periods. After 5 years of such abuse, it still turns the
engine (Rotax 914) over quite briskly. Prior to first flight, I'm troubleshooting
a few last gremlins in the instrument panel and it will run the panel all
day long. When it's time to replace it, I'll have no hesitation replacing it
with another new Odyssey.
Just my two bits.
