In my 30+ years of riding and owning motorcycle, I have never used a battery tender. I bought one about a month ago to use with my other Honda motorcycle. Today I finally got around to hooking it up. Do I leave it connected all the time? The last guy who owned the bike always had it on a tender, but when I got it I had to put a new battery in and put on a new rectifier. Once this bike is sold, I will use it on the Valkyrie. I don't ride but about once or twice a month at the moment so the bikes really just sit in the garage. But I want to make sure that when i do want to ride, they are ready. Are you guys using one? What are your thoughts on them?
