Well... I've found that if you're going to use a crimp joint on the battery lugs, you want a vise to do the crimping if possible. The longer the handle on the vise, the better! (For the best quality of crimp, that is.)

There is also a bag of copper connections in the KOP; those can be used with the batteries. Make sure the wire is between the plates, then screw down as hard as possible.
