  • This is heavy duty high quality battery cable
Size: 20 Feet Color: Black
Best feature is this cable is extremely flexible and easily bends around even the tightest corners. This cable was able to fix my charging problem I had on my truck. Just needed some small ring terminals and replaced the charge and ground cables on my truck
