Ancor Yellow 4 AWG Tinned Copper Battery Cable - 250'

The Ancor Yellow 4 AWG Tinned Copper Battery Cable – 250' is a marine-grade power conductor engineered for the demanding electrical demands of boats, RVs, and offshore vessels. Built to exceed UL 1426, ABYC, and U.S. Coast Guard CFR Title 46 standards, this 4 AWG tinned copper battery cable delivers reliable current distribution in the harshest saltwater environments. The 250-foot spool provides sufficient length for large vessel installations, equipment runs, and backup spares without mid-project shortages.

Premium vinyl insulation rated at 600V protects conductors across the full operational temperature range—105°C dry and 75°C wet—while maintaining flexibility even at extreme cold (-40°F). The tinned copper core resists oxidation and corrosion far more effectively than bare copper, a critical advantage in salt-air and salt-spray exposure. The cable resists battery acid, diesel fuel, gasoline, abrasion, and UV radiation, eliminating the need for frequent replacement due to environmental degradation. Tinning extends conductor life by preventing galvanic corrosion at connection points, a common failure mode in traditional battery cables exposed to marine conditions.

This cable serves deep-sea anglers, commercial fishermen, marine construction crews, and boat owners managing complex electrical systems. It's the preferred choice for main battery bank connections, engine start circuits, and auxiliary power distribution where downtime isn't acceptable. The 4 AWG gauge balances current capacity with flexibility, making it suitable for high-amperage applications without the stiffness of heavier gauges. A 250-foot bulk spool suits fleet operators, marine technicians, and serious boaters who standardize on a single, proven product rather than buying multiple shorter spools.

Ancor marine-grade wire products have become the industry standard because they solve the real problem: ordinary automotive battery cable fails in saltwater, requiring constant maintenance and replacement. This cable eliminates that cycle by addressing the root causes of failure—corrosion, UV breakdown, and cold-weather brittleness. For vessels that spend weeks offshore or work in tropical climates, the investment in premium cable during initial installation prevents emergency repairs at sea.
