Ancor #4 Red 25' Spool Tinned Cooper

The Ancor #4 Red 25' Spool Tinned Copper battery cable is the marine-grade electrical backbone that serious boaters and anglers depend on for reliable power distribution. Whether you're running electronics on a center console, powering an auxiliary engine, or connecting battery banks on larger vessels, this 4 AWG tinned copper conductor delivers the amperage capacity and corrosion resistance needed in saltwater and freshwater environments. Built to exceed UL 1426, ABYC, and US Coast Guard CFR Title 46 standards, it's engineered for the harsh conditions that offshore and inshore boaters face daily.

Constructed from tinned copper, this cable resists oxidation and corrosion far better than bare copper, a critical advantage when exposed to moisture, salt spray, and UV radiation. The 4 AWG gauge (19mm) provides excellent current-carrying capacity while remaining flexible enough for tight engine compartment installations and clean wiring runs. The red insulation jacket clearly identifies positive polarity, preventing cross-connections that could damage electronics or create fire hazards. The 25-foot spool length offers enough reach for most installations while minimizing waste and reducing splice points that compromise electrical integrity.

This marine-grade cable suits battery-to-starter connections, main distribution runs, alternator charging circuits, and auxiliary power feeds on fishing boats, cruisers, and center consoles. Anglers running multiple electronics—GPS, sounder, autopilot, and live bait systems—benefit from the stable voltage delivery and low resistance that tinned copper provides. Installation pairs seamlessly with marine-grade battery terminals, breakers, and fused switches. The spool format allows custom sizing while maintaining professional-grade construction that won't degrade after one season in the water.
