The first Odyssey PC680 went 9 years before replacement. It was still
going strong when I took it out because of age. I still use it in my shop
for various tasks The replacement PC680 is now 5 years old with never a
hint of faltering. Paid less for the 2nd battery than I did for the first
one in 1999. I use the 'Battery Tender' on them when the plane is not in
use. The tender is hooked to a timer that operates 12 hours daily.

I installed two Odyssey PC545 batteries
during the build in May 2008.
First flight was back in February and about a
month ago I thought I sensed a little less cranking power on startup.
On
start on the last flight, the prop would not pass through the compression
stroke so I waited a bit, hit the starter again and even through there was a
bit of hesitation, motor started normally. So my uneducated guess is that
these batteries are tired and have lost a lot of there cranking power. They
have always been maintained on an Odyssey Battery Minder and with a check on a
battery tester, they're still in the green. Anyway, two new PC545 will be
installed today.
Everybody else having good experience with their Odyssey
batteries?
Angier,
Five years is pretty good service life for
batteries, but generally, the Odesseys should do better,
especially since you've kept them in good condition/lightly used.
I
have two independent electrical systems on my IV-P, using two PC 680s each. I
replaced the pair of batteries I bought in 2006 last year, and was planning to
replace the 2008 batteries at this condition inspection. Both sets still
crank the airplane well, but this is one area where I'm "second guessing," so
I could use some factual information as well. For example, is there a
valid test for power available, etc.
One other note. These batteries
require a higher charging voltage than "regular" batteries. Be sure your
regulator is adjusted to the specs called for in the Odessey literature. Can
send same if needed, but also available
on-line.
