Needed a replacement and this one had good reviews. Bike turns better than it did when new, reported 11 lbs lighter than AGM. It is incredibly light, the box feels empty, it was a little disconcerting to begin with. Built in tester is IMO a little silly, easier to plug a meter into the battery tender leads than to take the seat off and push the button. I don't know if the dealer put the wrong battery bolts in, but they would not tighten all the way without bottoming and i needed the "retrofit kit" which is a couple of shorter battery terminal bolts. My bike wasn't supposed to need them. I'm going to guess Bosch makes it for Harley .
