Ancor Red 4 AWG Battery Cable - 100'

The Ancor Red 4 AWG Battery Cable – 100' is the backbone of any serious marine electrical system, whether you're running a saltwater center console, cruising inland waterways, or powering auxiliary systems on a deep-sea fishing platform. Built for the unpredictable environment where water, vibration, and corrosive salt air are constant threats, this cable delivers the reliability anglers and boaters depend on when they're far from shore and power failure isn't an option.

Ancor's marine-grade construction uses tinned copper stranding throughout, which sacrifices none of the conductivity of standard copper while providing superior resistance to corrosion and electrolysis—the silent killers of boat electrical systems. The 4 AWG gauge handles heavy-draw applications like starter motors, thruster systems, and high-amperage battery chargers without voltage drop over distance. Ultra-flexible Type 3 stranding resists the fatigue caused by constant engine vibration and the flexing that occurs during rough seas, ensuring the cable maintains its integrity across thousands of miles and years of hard use. The 100-foot length covers everything from engine compartment runs to remote battery banks, auxiliary power systems, and shore-power installations on larger vessels.

This cable is essential for any boater who demands zero downtime when running electronics, bilge pumps, or navigation systems in harsh marine conditions. Commercial fishermen, charter captains, and serious cruisers choose Ancor cable because it's built to Coast Guard standards and won't degrade in the salt spray environment where cheaper alternatives fail within seasons. Installation is straightforward with standard battery lugs and terminals; the red insulation clearly marks positive circuits and integrates seamlessly with any 12V or 24V marine DC system. Whether you're rewiring a restored classic or upgrading to true redundant power distribution, the 100-foot spool provides flexibility for custom routing around engine compartments and through bulkheads.
