This is kind of a nonissue because I figured out what I have to do. I was just wondering if anyone else has had this problem or knows why this happens. For the first 3 years I owned my bike, I didn't have a tender, so I would unhook the battery and bring it in the house in the winter. The fourth year I bought a tender and I started keeping it on the battery. Within a few weeks, the battery slowly died. I figured 4 years is about normal lifespan, so I bought a new battery and kept the tender on it. Same thing happened. Each time I would start it, it would turn over a little slower than before until not enough juice to start the bike. I figured I got a bad battery, so I got a new one. Same thing, battery dead within a month, so it has to be something with the tender. The next battery, I started unhooking the battery before putting the tender on. This solved the problem. This battery is 7 years old and still going strong. I heard the '05 have an electrical system that draws some voltage when the bike is off, so would this have something to do with it?
