Everybody else having good experience with their Odyssey batteries?


Angier,
Five years is pretty good service life for batteries,  but generally, the O=
desseys should do  better, especially since you've kept them in good condit=
ion/lightly used.=20

I have two independent electrical systems on my IV-P, using two PC 680s eac=
h. I replaced the pair of batteries I bought in 2006 last year, and was pla=
nning to replace the 2008  batteries at this condition inspection. Both set=
s still crank the airplane well, but this is one area where I'm "second gue=
ssing," so I could  use some factual information as well. For example, is t=
here a valid test for power available, etc.

One other note. These batteries require a higher charging voltage than "reg=
ular" 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.
