Ancor #2 Yellow 25' Spool Tinned Cooper

The Ancor #2 Yellow 25' Spool Tinned Copper battery cable is essential marine electrical infrastructure for any boater serious about safe, reliable power distribution. After years on the water, you learn quickly that a single corroded battery cable can strand you miles from port or worse—create a fire hazard in the engine compartment. This 2 AWG cable is engineered for saltwater environments where standard copper wire fails, delivering the dependable electrical performance your boat's starting and charging systems demand.

Built from tinned copper stranding, this cable resists corrosion and electrolysis—the twin enemies of marine electrical systems. The tinning process coats each copper strand with a protective layer of tin, preventing the green oxidation that degrades conductivity and increases voltage drop. Ultra-flexible Type 3 stranding eliminates the fatigue cracking that rigid cables suffer when engines vibrate or wires route through tight engine bays. The 2 AWG gauge (32mm²) handles high-amperage loads required for modern marine engines, alternators, and battery banks without voltage loss or overheating.

Whether you're upgrading an aging cruiser, rewiring a fishing boat's dual-battery system, or installing a new auxiliary power setup, the 25-foot spool length covers most applications from battery to engine block, switch panels, or remote loads. The yellow jacket provides visual identification—critical when multiple cables run through tight spaces. This cable meets ABYC (American Boat and Yacht Council) marine standards, ensuring your boat's electrical system meets insurance and safety code requirements. Installation requires proper tinned-copper lugs rated for 2 AWG; always use marine-grade crimpers and heat-shrink tubing rated for saltwater exposure to complete the job correctly.
