Odyssey PC680 Alternative?

[rockitdoc]

I put the Odyssey PC680 in two years ago while beginning the wiring of my bird. It has been used for little other than checking circuits. I use an external power supply while learning the Dynon HDX. So, why is the Odyssey dead, dead, dead and cannot be revived after so little use. Oh, my shop is climate controlled. So, no cold winters.

Very disappointed in this battery, unless there is something I did to cause this.

Any thoughts appreciated and any alternatives that are more reliable appreciated, as well.

This is the one I mentioned today. It gets charged by my Norco. I figure if it goes TU, it was cheap. If it survives, I'll use it.

I've bought and installed 4 of the Odyssey PC-680's in 10 years of flying my RV-9A. They don't seem to last much beyond 2-3 years. I don't normally keep the battery on the tender, and I live in a very mild climate (San Diego area). My current battery failed me a couple of times this last month, so I decided to move to the EarthX.
