Ancor Red 4 AWG Tinned Copper Battery Cable - 250'

The Ancor Red 4 AWG Tinned Copper Battery Cable in 250-foot spools is purpose-built for marine electrical systems where corrosion resistance and voltage stability are non-negotiable. This marine-grade battery cable exceeds UL 1426, ABYC, and U.S. Coast Guard standards (CFR Title 46), making it the standard choice for boats ranging from center consoles to offshore fishing vessels and cruising sailboats.

The 4 AWG tinned copper conductor provides low electrical resistance for efficient power delivery from battery to engine, alternator, and auxiliary systems. The premium vinyl insulation is rated for 600V and temperatures up to 105°C in dry conditions and 75°C in wet marine environments—critical for engine compartments and below-deck installations. The tinned copper construction resists salt spray, battery acid, diesel fuel, oil, and UV degradation far longer than untinned copper, eliminating the corrosion failures that plague standard automotive cable in saltwater exposure. The cable maintains flexibility even at extreme cold (-40°F), essential for winter boating and northern climates.

This cable serves weekend fishermen upgrading to larger outboards, serious offshore anglers running multiple fish finders and live wells, and cruising sailors installing or replacing battery banks. The 250-foot spool format allows one purchase to handle main power runs, auxiliary circuits, and future upgrades without waste. Whether routing power to a new trolling motor, upgrading charging systems, or installing battery isolators, this cable handles the demands of salt air and constant vibration that shorten standard marine electrical components.
