You can get it at advanced auto, pepboys, walmart. etc. There is nothing to feel unsafe about since it is the same thing as a car battery just smaller. The battery teminals are different. They are small semicircles, with a hole in them. All you do is: Think about your cars battery terminal wires. It is a split circle with a screw that tightens it, undu the screw, put "circle" over the terminal then run the bolt through the circle and battery terminal. Takes 2 minutes.
