I bought the Harley battery tender. I'd heard how horrible the battery removal process was, but really -- it was 15 minutes maybe. No giant deal. The worst part of the whole install was that after I'd already put the eyelet lead on, and was trying to figure an ideal place for the charging point, and settling on a spot by the left passenger footpeg, I found that there was something else already there blocking it...
Yes, a battery tender port. Seems the dealer had already installed one! So now I have two, which is actually perfect, I'm turning the one I installed into a permanent USB charger for the FP3 phone/tablet, so I'm happy with it this way, but I sure wish I woulda known they'd already put one on.
Two reasons I bring this up: first, it really isn't any big deal to get to the battery to at least put the positive terminal lead on. Pulling the entire battery out would have been more of a hassle but there's no need to in this install, because you can put the negative lead on the frame (as illustrated in the battery tender instructions). I don't know where they did install the positive lead, but it wasn't on the battery itself. The negative lead was put on the same negative ground terminal that Harley suggested to put their battery tender to.
Second, you can definitely install the battery tender harness without attaching it directly to either of the battery's terminal, because that's the way the dealer had installed their harness. There was nothing directly attached to my battery's terminals.
