I have a 2006 Road Glide. No problems with my battery or my charging system. When I plug in the battery tender to the bike, it quickly goes to a flashing green light (on the tender), which indicates 80% charged. However, I have let it charge for several hours and it does not reach the point of a solid green light, indicating a complete charge. I bought a brand new battery tender and it does the same thing. Has anyone else experienced this problem??
