It's possible - I ride to work quite a bit, but I have to admit, I've lived closer to work in the past and never had this issue.

This statement is complete baloney and the proof is from Yuasa in the link below
"Unlike lead-acid batteries that use a liquid type of electrolyte, AGM batteries feature a chemical structure that doesn’t have a liquid type of electrolyte."

Once activated an AGM battery is maintenance free and cannot be topped up.

Off the bike - it went from 12.81 to 12.64 on about an hour and a half off the bike. I'm leaning toward bad battery caused by improper tender

It was much newer than 15 years, but if you've been using it regularly on an AGM for more than a year with no issues, maybe that isn't my problem. Quick update, the battery seems to have stabilized at 12.63V, and I checked my wife's 3 month old Pacifica with an AGM and its also 12.62V, and my 9 month old Jeep with an AGM is 12.20V, so I'm not really buying into the whole 12.8V is 100% and 12.6V is 75%. at 12.2, my Jeep is only around 40%.
So, back to the bike, I played around and check cables and found that while the nut on the starter cable was tight, I was able to get a good half turn out of it. I'm going to leave the battery out for the night, check voltage and maybe a few more cables in the morning, then try again. I'll update afterwards.
I picked the wrong year to try sober spring LOL
