Aside from the motorcycle issue. Have any of you with the dead batteries measured drain, alternator voltage, and battery voltage?
The PC680 is a motorcycle battery, so it isnt meant to be able to run the amount of components many cars on here have, or anywhere else for that matter. They are not strong by any means. Simply lighter, not too expensive, and reliable (for me at least). I also do recommend any of the Deka offerings. You can find the ETX16L for like $80 shipped and that has been bulletproof so far and the car sees a tender in awkward intervals (5 months no, 2 days yes, 1 year no, etc). Battery still juicy.
Weight is 17lbs and it is the Braille 2317 pattern so I use the 2317 mount.
I am going to dig in to see if Odyssey has changed any manufacturing processes
Also are any of you guys doing an install charge? I was always taught to put AGM batteries on a tender until they are fully charged before full use. I cant see that is the reason they last so long as that would be fallible reasoning, buy its a good habit. They always come undervolted
