Performance: The battery cable refers to the line that connects the battery to the car machine on the car, and is usually used as the power connection for low-power devices such as the car audio system, electric horn, and navigation system. The battery cable is directly connected to the car battery, and the voltage is relatively stable, which can provide a more stable power supply for the device. The red cable represents the positive, and the black cable represents the negative. Nickel-plated copper lugs for corrosion and oxidation resistance. Good PVC insulated for the cables. Cable ends are sealed with heat shrink tubing for heat insulation. Made of: The battery cable is made of copper to provide maximum conductivity. They are wrapped in a PVC insulating sheath, wear-resistant and waterproof. They are also heat-resistant and flame-retardant to ensure safe use. Tip: Removing: Remove the negative (black) cable before the positive (red) cable. Installing: install the positive (red) cable first before the negative (black) cable. Always wear safety glasses when working. Please make sure to measure the size before placing an order! Installation Guide: Easy Installation.
