Default Odyssey Dry Cell Life/Failure Modes

I installed an Odyssey 680 in my RV-6 Jan of 2003 and it is still going
strong, I have been very happy with the results I get out of it. I have
had much better service from it than I have any of the so called
aircraft batteries.

I replaced the one on my RV after just under 2 years.

It was a "soft" failure in that there was never a step change in
performance, just gradual degradation over time. Eventually the cranking
performance became problematic.

I was pleased that the retailer provided a new battery under warranty. The
new battery is going strong after a year.

I installed an Odyssey Dry Cell battery in my Fly Baby about four years
ago, and
I've been very happy with it.

Lately, though, my voltmeter has been running a bit low, both before the
engine
starts and when the plane is cruising. My Microair transponder has a
voltmeter
function, and I've verified that the battery is running about a half-volt
lower
than I'm used to.

The engine starts so quickly I can't really tell if the battery charge is
low.

Anyway, I was figuring I had more problems with the generator/regulator,
but
when I put an external charger on the plane this morning, the initial
charge
current was quite a bit lower than I'm used to seeing when a battery is
low on
charge.

So my questions run down to:

1. What kind of life are people getting with these Odyssey batteries, and
2. When they fail, what kind of indicators do you see? Does it just
suddenly
refuse to hold a charge, or are there early warning signs?
