The Battery Tender® Junior is much more than a trickle charger. It has a brain. It's lightweight, compact, and fully automatic; very easy to use, especially in small spaces. It will keep your battery fully charged so that it is ready to go when you are.
And you hardly have to be mechanically inclined to use one of these -- just connect the pigtail connector to your battery terminals, fish it out from behind a side panel or out from under a seat when you need it, and plug it in. The light will flash solid as soon as you plug the wall unit in. Once connected properly to a bike you'll see a solid red light to indicate it's charging, and once it's topped off Green Means Go.
As an added bonus you can also use the pigtail connector to plug in a simple USB charging adapter for keeping your phone or other electronics topped off while you ride.
