best investment of the year
Once installed all I have to do is pull in the garage, plug the maintainer into the supplied battery connector (that tucks nicely under seat for clean look) and forget about it until I'm ready to leave again. Keeps battery working like new! I never worry about cold starts anymore.

PROS: Plug It And Forget It, Fool Proof Installation

CONS: Didn~'~~t Get It Sooner

Nice Battery Tender
Perfect to keep the battery charged in the Fall/Winter. I like that it stays cool when charging.

I removed the battery terminals and hooked up a Powerlet connector so I can charge my BMW motorcycle through the Powerlet outlet. Just plug it in and let charge -- perfect!
