OEX ACX0903L 6 B&S Single Core Battery Cable, Red 100M Roll

OEX ACX0903L Australian Made 6 B&S Single Core Battery Cable Red 100m Roll OFHC Copper V90

The OEX ACX0903L is a 6 B&S single core battery cable in red, supplied on a 100m roll. Made from oxygen free high conductivity (OFHC) copper, it is engineered for high-current positive supply wiring in automotive, caravan, marine and off-grid power applications. Rated to V90 (90°C) with UV stabilised PVC insulation and a voltage rating of up to 120V. RoHS compliant and Australian owned and made. Covered by a one year warranty. The ACX0903L pairs directly with the OEX ACX0902L black 6 B&S cable for a matched positive and negative installation.

Product overview

The ACX0903L is the 100m roll version of the ACX0903 red 6 B&S single core battery cable, suited to trade workshops and fleet operations running multiple high-current positive supply installations from a single roll. Red is the conventional positive wiring colour in automotive and marine electrical installations, making the ACX0903L the natural choice for battery positive supply cables, dual battery main positive feeds, starter motor and alternator positive leads, winch power cables and high-output amplifier power feeds.

OFHC copper with less than 0.001% oxygen content minimises resistance, reduces oxidation over time and maximises current transfer efficiency across the full 100m roll. This is a meaningful difference in high-current applications such as dual battery systems, winch wiring and amplifier power feeds where voltage drop across a cable run directly affects performance. The UV stabilised V90 PVC insulation handles sustained underbonnet heat and direct sun exposure in Australian conditions. The 100m roll suits trade and workshop use, vehicle fleet fitouts and large-scale installations where consistent gauge and insulation specification across the entire job is required.

Features and benefits

OFHC copper conductor: Less than 0.001% oxygen content minimises electrical resistance, reduces oxidation and maximises current transfer efficiency, important for sustained-load applications including dual battery systems, winch wiring and amplifier power feeds.

Red colour coding for positive supply runs: Red is the conventional positive wiring colour in automotive and marine electrical installations, assisting with circuit identification and reducing wiring errors in high-current battery supply circuits.

Australian owned and made: Manufactured in Australia to local quality standards, ensuring full traceability for professional auto electricians and fleet operators who specify domestic product.

V90 temperature rating (90°C): Insulation rated to the Australian V90 standard, withstanding sustained underbonnet temperatures and heat generated by high-current loads in enclosed wiring runs.

Up to 120V voltage rating: Covers all standard 12V and 24V automotive systems with headroom, as well as low-voltage solar, caravan and marine power applications.

UV stabilised PVC insulation: Resists cracking, hardening and degradation from prolonged sun exposure, suited to underbonnet, rooftop and exterior cable runs in Australian outdoor environments.

RoHS compliant: Confirms the cable is free from restricted hazardous substances including lead, cadmium and mercury.

100m roll: Trade format suited to workshop supply, fleet fitouts and large-scale installations. Consistent gauge and insulation specification across the entire job from a single roll.

Frequently asked questions

What is the difference between the ACX0903 and the ACX0903L? Both are 6 B&S single core red OFHC battery cable. The ACX0903 is supplied on a 30m roll and the ACX0903L is supplied on a 100m roll. Select based on the quantity required for your installation workload.

What does 6 B&S mean and how does it compare to other cable gauges? B&S (Brown and Sharpe) is an Australian wire gauge standard. 6 B&S is a heavy-gauge cable suited to high-current applications. Confirm current carrying capacity with OEX or a licensed auto electrician to ensure it matches the load requirements of your specific installation and run length.

Why does OFHC copper matter in a battery cable? OFHC copper has less than 0.001% oxygen content, which reduces electrical resistance, limits oxidation over time and maintains conductivity in high-heat environments. This is important for sustained-load applications including dual battery systems, winch wiring and amplifier power feeds where voltage drop across a cable run directly affects performance.

Does this cable pair with the OEX ACX0902L black battery cable? Yes. The ACX0903L red and ACX0902L black are matching 6 B&S OFHC cables from the same OEX range, designed to be used together for positive and negative wiring in a consistent, professionally matched installation.

Is this cable suitable for solar and caravan off-grid power systems? Yes. The 120V voltage rating, UV stabilised insulation and V90 temperature tolerance make the ACX0903L well suited for solar, caravan and off-grid power system positive wiring. Confirm current carrying capacity for your specific cable run length with OEX or a licensed auto electrician.
