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!

I actually bought a second one for my neighbor. She travels a lot and her car battery would drain significantly. I think there is some "leak" but this device keeps the battery in top condition.
