Ancor Black 4 AWG Battery Cable - Sold By The Foot

Ancor Black 4 AWG Battery Cable sold by the foot is the marine industry standard for high-amperage electrical connections on boats and larger watercraft. Whether you're upgrading an aging power distribution system, extending a battery run to an auxiliary engine, or installing a new thruster or windlass, this tinned-copper cable delivers the reliability demanded by saltwater and freshwater environments alike. Available in single-foot increments, you purchase only what you need—no waste, and no compromise on quality.

The 4 AWG gauge delivers 95 amps at 10 feet, making it ideal for large battery banks, main distribution feeders, and high-draw accessories. Ancor's marine-grade tinned copper stranding resists corrosion and electrolysis—critical in the harsh, salt-laden atmosphere where conventional bare copper fails within months. The Type 3 ultra-flexible stranding resists fatigue from engine vibration and repeated flexing around tight corners or through cable trays, eliminating brittleness and cracking that compromise safety. Black insulation identifies this as a negative or ground conductor in standard marine wiring color codes, ensuring proper circuit polarity and reducing diagnostic confusion.

Serious boat owners, marine electricians, and yard technicians trust Ancor cable for mainline battery connections, engine-start circuits, and high-current charging systems where failure is not an option. It pairs seamlessly with proper lugs (sold separately) and is compatible with industry-standard battery terminals, alternators, and distribution panels. Measure your run twice, order the exact footage needed, and enjoy years of dependable, corrosion-free service—the hallmark of professional marine installation.
