I have a 5-6 year old Odyssey PC680 battery which was installed new in the final stage of building my RV4. Atter that it has been in the hangar for a year during final assembly. I have been doing some engine running last summer and then have had a battery charger connected all the time. Skyview has shown 13.7 volts when it is fully charged. Yesterday I started the engine and ran it for 10-15 minutes and after that Skyview showed 10.3 volts. I suspect the battery has gone bad but I'm not sure. Isn't this discharge too quick for a healthy battery?
