TQ Battery cable usually refers to automotive battery cable and refers to the large gauge (thicker) wires used in automotive , from small cars to tractors and freight trucks. Typically, battery cable is used to supply power from the battery to the starter engine or as a connection to ground (i.e. the car frame). Battery cable can also be used to connect the battery to other electrical components (e.g. fans, A/C, lights, etc.), though smaller gauge automotive wire may work instead. Some electrical power systems also use battery cables as the connections between battery banks, inverters, and solar panels in solar power installations. However, for applications that are not under the hood, most people prefer welding cable, since it is more flexible, durable, and can handle more current. Battery cable may range in size from 4/0 to 6 AWG. The conductor material for car battery cables is typically stranded copper wire to provide some flexibility and is made for use as connections between automotive batteries and other units that draw high amounts of current. Therefore, they need to be able to handle the amps that will be drawn and primarily need protection against heat, oil, and battery acid. Depending on the insulation, some battery cable will have extra protection against cuts, tears, and abrasions from rubbing against machine parts.
