Battery Cables for Commercial Vehicles

Commercial vehicle battery cables carry the high starting currents demanded by large diesel engines. A cable of inadequate cross-section will create resistance, reducing cranking power and generating heat that degrades the cable over time. Truckstop stocks battery cables in the gauge ratings appropriate for HGV starting systems, ensuring reliable starting performance and long service life.

Choosing the Correct Battery Cable Gauge

Cable gauge must match the amperage drawn by the application. A typical HGV starter motor draws between 800A and 1500A during cranking. For main battery cables and jump-start applications, 25mm2 cross-section is a minimum starting point; 35mm2 and 50mm2 cables are common for direct battery-to-starter connections on larger engines. All cables stocked by Truckstop are rated for their application.

What gauge battery cable do I need for an HGV?

For most HGV applications, a minimum of 25mm2 cross-section cable is required for battery connections, rising to 35mm2 or 50mm2 for main starter and earth connections on larger engines. Jump-start cables for commercial vehicles should be a minimum of 35mm2 to handle the surge current during starting without overheating. Always match cable rating to the amperage of the application.

Are these cables suitable for 24V truck systems?

Yes. Battery cables are not voltage-rated in the conventional sense for low-voltage DC systems; the important specification is the current rating. Cables stocked by Truckstop are suitable for both 12V and 24V commercial vehicle applications. Confirm the current rating matches your application before ordering.

Do you stock battery earth cables as well as positive leads?

Yes. Earth or negative battery cables are stocked alongside positive leads. Good earthing is as important as the positive connection for reliable starting performance; a high-resistance earth connection causes the same symptoms as an undersized positive cable. Earth straps, earth cables and negative terminal connectors are all available.
