I ended up jumping it with a car.....had to charge it for quite a while before it started. I initially had left it at the auto parts store for 5 hrs so they could slow charge it they said. When i picked it up they said it was good to go and charged me 0. I'm guessing thats because they did 0

Im going through a similiar issue on an FXSTB. Bike was purchased AUG 2007. A few weeks ago I went to start the bike after riding 2 days prior, and wouldnt start. Put it on battery tender (HD) and after all day went green, started. Left it on tender for another day.
Week later, rode on Sunday all day was fine. Then on tender till Thurs, go to start aroun 10 a.m., starts up, then shut if off while some came over to talk to me, and boom, wouldnt start again. Just fast clicking. Checked terminals, fine. Tender again all day. Went green, around 6 p.m. starts and drive to bike shop for bike night. Stop to get gas, turn off. Go to start, and it starts, just not fast like it use to. Bike shop checks it out, the bike seems fine, is charging while on, but slow a little starting. After bike night, go to a few places, start, stop, little slow starting but works. SAT ride about 200 miles, stopped a few times, and slow starting, so now im getting worried.
Today, doesnt start after 2 days on charger that is green. Check connections. take meter. Battery is at 12.3/4 volts. Should be around 12.5 and higher but still ok. Kept meter on it, hit the starter, drops to 4 volts. Bad sign, battery not handling the load.
Take battery out, bring the battery shop (industrial) my brother works at, do a load test there and battery is discharged. Voltage is there, but put any load on it, and it drops voltage. Usually bad battery, or the tender is not really charging it. Gonna leave overnight to see if it comes back, but has me worried for peace of mind, just gonna get new battery for now while that test is ran.
less than two year old bike (doesnt mean battery was on tender or when it was charged up initially), but still, that is ridiculous.

Battery tenders plus will keep the battery at 13.2v if the battery is in good condition. If the battery had been discharged the recoverability to full charge is slim. A lot of people will poo poo the use of a tender plus But that's one of the quirks of an AGM battery. "Bar hopping", short runs only provide a surface charge and that surface charge is depleted on starts. H-D's electric charging is for the battery then the battery provides the power to electrics, would be nice if the H-D electrical charge system could also service the bikes electrics while charging the battery.
