I am running a 320 Lycoming with 9:1 pistons. In the last 12 years I have gone through 3 Odyssey 920's and 2 Concord 35AXC. The batteries last about 2.2 years each. I just purchased a EarthX 900 battery and the Optima Charger. Is there a better choice for batteries that may last longer than 3 years? I am hoping the earthX will last at least 4 years due to the higher cost.
I should mention that 5 of those years were in Mississippi and the other 7 in Michigan. So it doesn't seem to matter what the climate is like. Who has had good luck with battery's and what types did you use?
