I recount it because it may help others. When I started the project of getting my 84 Asp running the battery in the bike was the typical old acid battery. It was bad so I replaced it immediately with an "Extreme Magna Power" AGM battery purchased at the local Advanced Auto Parts. As I started to work on the bike I found the battery constantly drained. When I could not find an obvious short I took the battery back to Advanced Auto, they tested it and told me the battery was fine just needed a charge. I went back to work looking for the drain. Took the battery back again when I could not find a short, they tested it again and told me again it was fine. At that point I made a post here and started again. After following the advice all of you gave me, especially the using an amp meter which showed no drain, I charged the battery on the bike and logged every 2 hours the drop. Then took the battery off the bike charged it again and logged the voltage every 2 hours. Went back to Advanced with the battery and my log (off the bike battery dropped from 12.32 v to 9.92 v in 4 hours). They put it on the tester and again told me the battery was fine, after a discussion with the guy, he finally gave me a replacement (battery had a 1 year warranty). Since the new battery went in, no problem after 5 days. I have no idea why the battery tested good with the tester Advanced Auto had but would not hold a charge. But if others have a absorbed glass mat battery it may be something about testing them that will give a false reading. Thanks to all of you who provide help to those of us starting off on these projects.

I have had a car battery do that. Put a load to start and no go. Was bad but tested good.
Enjoy the ride. They are all good, just some better than others.

Because what they were testing for (the ability to put out a massive starting current) and what the problem was (self-drain likely due to bad cell) are two completely different things. The battery was (obviously) bad.
