True copper battery cables that are high quality
Size: 10ft, Color: 4awg
I love having heavy duty cable on hand for my cars. It's so nice to be able to make your own starter and alternator cables when restoring cars. These cables are 100% copper, not CCA (copper clad aluminum) like many others are. Copper is far superior for conductivity and handling higher loads. The rubber on the cable is thick and yet very flexible..it's clearly marked and seems very durable. I like to use a hydraulic crimping tool and then add marine grade heat shrink tubing with the adhesive inside of it to keep it as weatherproof as possible.

Easy to work with
I bought this to wire up an airplane I built. I had to cut it into 10 separate pieces and crimp and solder lugs to each end. It was just the right length for what I needed and I'm very happy with the results.

Good product. I will buy again.
Great value. It did show up covered in small fiberglass particles which was a bit annoying.

Excellent true copper wires 6 AWG cable
I bought them to use on sub-wiring job running 12vdc from positive terminal to custom fuse box of my van. This cable maybe mainly for welding machine, but it works great for my project with its true copper wires and high flexibility.
