You need to slowly charge your battery with a trickle type charger (battery tender). Bring it up slow and maintain it with the tendor. The bike's charging system does OK keeping a battery charged, but ain't good for charging a battery.

Agreed, you can burn a deep cycle battery ( like the one in your bike, camper or boat) by charging it with out a deep cycle battery charger, or simply jumping it. I believe the max you want to put in at a time would be 10amps.
Sears sells a manual charger that works on your car also for about 30$
But I recommend spending a little more for the Automatic charger that will monitor the battery to see when its full and not burn it.
or a good trickle charger will work.
You may want to verify that your ground cables are in good condition and grounding properly.

Did you try a voltage meter at the battery posts? At that point you should be throwing about 14-14.4 volts to the battery if everything is charging properly. Next guess would be the stator starting to short. Hope this helps.

Harleys starters can be picky too. I know that come spring if I don't get a full charge on my battery, I will end up stuck somewhere clicking.

all bike batteries i've bought are not ready out of the box, and they need a very slow deep charge before use, like everyone already said. 1.5 amps is ideal. battery tenders are great
i do know the dealers around here will charge the battery for you for free if you buy it there, so if you don't have the proper equipment there's an option.

Hey wideglide I bought a voltmeter with L.E.D.s that at least tell you how many volts are being produced by the charging system. It's from Kuryakyn and available thru most aftermarket vendors. I've got mine mounted to the front master cylinder. Harleys run off the batteries juice and the charging systems only job is charge the battery, not running the electrics. An AGM battery with a battery tender plus is the best way to maintain that battery.

Charging System
You will have to ride it about 10-20miles to charge the battery back up from starting it. I've noticed that if I don't ride far enough after I start the bike, the battery tender stays on high charge a lot longer than usual. A battery tender is a great idea.
