Review on Schumacher Battery Charger and Maintainer Cable Connector - Quick-Connect Ring Terminal for Effortless Connection by John Wood

Good product. Fair price. Just pay attention to the polarity. When connecting to regular third-party cables, you will find that the positive and negative sides of this cable are reversed. What I did was use a black marker and paint the red heat shrink tubing black. You can also color it with paint. After checking, I painted the other side red. It was quicker than cutting the wire and using new heat shrink tubing and clamps.
