I just thought I'd put this out there for those who may need a decent battery maintainer. Right now Napa currently has a nice 1.5 amp battery maintainer with battery pigtail on sale for $19.99, I currently have 3 maintainers that I've been using on all my bikes for the last several years. One of my Schumacher maintainers is going on the blink, so I just ran up to Napa and bought two of these as back up spares, a great price for a good maintainer.
