Go to Odyssey's website and read up on the battery. It charges differently than most batteries using a special charger. As already noted many people have reported these batteries don't do well when constantly connected to a charger, nor do they appreciate being fully discharged. Then may be recovered and the process is on their website. Once you have a fully charged battery, if you still have problems you will need to look for the problem with a voltmeter. Starter relays are among the most common problem but until you know where the voltage drop is occurring by measuring it your only guessing. Get a fully charged battery, testing it using Odyssey's instructions. If you still have problems, I'd suggest you go the AeroElectric group on Matronics for more specific help.

Bob Nuckolls & company can give you a lot of good info regarding electrical components and troubleshooting. As for who sells starter relays, www.bandc.biz also sells battery and starter contactors. >From my research the Odyssey PC680 is a great battery and that's what I bought for my not-yet flying project. I would however recommend that you do a search on the Aeroelectric site for some specific idiosyncrasies that the PC680 has in response to trickle charging. If I remember correctly, it can have some adverse reactions if the wrong charger is used.

I have a PC680 in my IO360 RV8. 100 hrs/yr. I don't particularly do anything to my battery - no trickle charging, I pretty much ignore it and do as I do with my car. Get in the plane, contact on, flaps up (electric) and do a cold start - starts almost immediately. After the flight, flaps down before shutting down the engine (sometimes I forget flaps down and do that after shutting down the engine). I kept my first battery 3 years, changed it when it showed signs of weakness. One year into the new one works great. Conclusion is use it normally. No need to trickle charge it constantly.
