The battery Tender Jr. comes with 1 set of permanent mount ring terminals & 1 set of mini jumper cable clamps so you can hardwire 1 car & use the clamps whereever they are needed.The 1-way quick disconnect on the cord makes things very easy to hook up & unhook. And it is maintaining my battery fine, no more dead car.

There are two things you need to consider when purchasing this item.
First, unlike its big brother, the Plus, the Junior is not temperature compensated. To find out more about that, go to batterytender.com, click on the FAQs link on the left and read item #18: “What is Temperature Compensation and how important is it?”
I was concerned about this, as living in the desert as I do, the temperature in my garage is 90 to 130 degrees most of the year and can drop to the 50s in the winter. I inquired about this to Battery Tender support and received this answer: “The Junior is not a temperature compensating unit, however, when the temperature is hotter, the unit will actually charge the battery a bit faster and it will not harm the battery.” I don’t know what to make of this, especially since compensation is so important according to their FAQ.
The other is to make sure you get the 4-step Junior which replaced the 3-step over a year and a half ago. On the back side of the packaging on the left side look for the reference to “Complete 4-step.”
That being said, I’ve been using a Junior for almost 6 months on my motorcycle so I can’t post up my experience as well as others here. I’m hoping it will provide my batteries with more service than the 14-16 months I’m used to.
By popular acclaim and editorial content, the Junior and the Plus have garnered untarnished reputations and withstood the test of time. For maintaining your battery, there really isn’t anything else out there.

This is an easy to install and use battery tender. If you store your motorcycle during the winter you should use one of these to extend the life of your battery.
