These small batteries are better off with a slow 24 hr charge on an under 1 Amp maintenance charger. Be sure to check the tightness of battery clamps. Modern Harleys even with alarm draw little more than 5 milliamps. Mine will easily go a couple of months on a cheap Walmart made in China AGM gell mat battery. Yours draws less than mine..

 

According to the dealer, all the connections were tight, the battery load tested just fine, several starts since they got it - both cold and hot - and no issues. They checked the draw on it and said it was the right amount. At this point they're going to keep the bike a few days and retest.
