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

Premium Australian-Made Battery Cable for Dual Battery, Car Audio, and 4WD Electrical Builds.

---

Product Overview

The OEX ACX0903L is a 100-metre roll of 6 B&S single-core red battery cable engineered for high-current automotive and electrical applications. Made from Oxygen Free High Conductivity (OFHC) copper, it delivers superior current-carrying efficiency and resistance to oxidation compared to standard copper alternatives a meaningful difference in dual battery systems, high-output amplifier wiring, and any installation where long cable runs or high current loads are involved.

Rated to V90 (90°C) and UV stabilised, this cable is built to handle under-bonnet heat, direct sun exposure, and the demanding conditions of Australian 4WD touring and professional auto electrical work. RoHS compliant and proudly Australian owned and made, the ACX0903L is a premium-quality product backed by local manufacturing standards.

Features & Benefits

• Oxygen Free High Conductivity (OFHC) Copper — OFHC copper contains less than 0.001% oxygen, minimising resistance, reducing oxidation, and maximising current transfer efficiency. This matters in high-current applications such as dual battery setups, winch wiring, and amplifier power feeds where voltage drop over a cable run directly affects performance.
• V90 Temperature Rating (90°C) — Rated to Australian Standard V90, this cable withstands the sustained heat generated in under-bonnet environments and enclosed wiring runs — a critical spec for installations that remain powered under load in Australian summer conditions.
• Voltage Rating up to 120V — Covers all standard 12V and 24V automotive systems with substantial headroom, as well as low-voltage solar and caravan power circuits.
• UV Stabilised — The outer insulation is UV stabilised to resist the degradation and cracking caused by prolonged exposure to the Australian sun — particularly important for any above-deck, rooftop, or engine bay cable runs.
• RoHS Approved — Compliant with the Restriction of Hazardous Substances directive, confirming the cable is free from restricted materials including lead, cadmium, and mercury.
• 100% Australian Owned and Made — Manufactured in Australia to local quality standards, supporting local industry and ensuring traceability for professional auto electricians and fleet operators who specify domestic product.
• 100-Metre Roll — A full-roll format suited to trade and workshop use, vehicle fleet fitouts, and large-scale installations where buying in bulk reduces material cost and ensures consistency across jobs.

Frequently Asked Questions

What does 6 B&S mean and how does it compare to other cable gauges?

B&S (Brown & 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 your auto electrician to ensure it matches the load requirements of your specific installation.

Why does OFHC copper matter in a battery cable?

Oxygen Free High Conductivity copper has less than 0.001% oxygen content, which reduces electrical resistance, limits oxidation over time, and maintains conductivity in high-heat environments — important for sustained-load applications like dual battery systems and winch wiring.

Is this cable suitable for use in a dual battery system or caravan build?

Yes. The 6 B&S gauge, 120V rating, V90 temperature tolerance, and UV-stabilised insulation make it well-suited for dual battery, solar, and caravan power circuit applications. Confirm current carrying capacity for your specific cable run length with OEX or a licensed auto electrician.

What does the V90 temperature rating mean?

V90 is an Australian Standard designation indicating the cable's PVC insulation is rated to a continuous operating temperature of 90°C — suitable for under-bonnet environments and enclosed wiring runs in Australian summer conditions.

Is this cable available in black for negative/earth runs?

The ACX0903L is the red variant of this cable. Contact OEX or your authorised reseller to confirm availability of a matching black cable in 6 B&S for negative and earth wiring runs.
