Ancor Battery Cable
Ancor Marine Grade Battery Cable: Built for the Harshest Environments
When your boat's electrical system depends on a reliable connection between battery and engine, the cable you choose matters enormously. Ancor has been the marine electrical industry's standard-bearer for over four decades, and nowhere is that reputation more evident than in their battery cable lineup. Unlike standard automotive or residential cable, Ancor battery cable is engineered specifically for the punishing conditions found on the water.
The Tinned Copper Difference
The foundation of the Ancor brand is their tinned copper wire. Every individual strand is electroplated with tin to prevent corrosion and electrolysis, which can "wick" up a standard bare copper wire and cause total system failure. In a marine environment, where salt air and moisture are ever-present, this distinction is critical. Ancor Marine Grade Battery Cable is manufactured from tinned copper stranding for maximum protection against corrosion and electrolysis, and the ultra-flexible Type 3 stranding resists fatigue due to vibration and flexing.
Performance Specifications That Exceed Industry Standards
Ancor Marine Grade wire products are the longest lasting and most rugged available, exceeding UL 1426, ABYC and US Coast Guard Charter boat (CFR Title 46) standards. All Ancor battery cable is flame retarded, UV inhibited, rated to 600V and 105°C. These aren't marketing claims — they're verified compliance benchmarks that matter when a boat's electrical system is put to the test far from shore.
The cable is resistant to salt water, battery acid, oil, gasoline, heat, abrasion and ultra-violet radiation. Ultra-flexible Type 3 tinned copper stranding provides maximum protection, and the cable stays flexible even in extreme cold (-40°C). This cold-weather flexibility makes Ancor battery cable an excellent choice not just for boats, but for any marine or outdoor application where temperature swings are the norm.
Ready-to-Install Assemblies and Raw Cable
Ancor offers battery cable in two primary forms to suit different installation needs. For custom runs, raw cable is available by the foot in a range of gauges — from 6 AWG all the way up to heavy-duty 2/0 and 4/0 — in both red and black to maintain proper polarity identification. Ultra-flexible Type 3 stranding makes it easy to pull heavy-gauge 2/0 or 4/0 cable through tight bilge spaces.
For simpler installations, Ancor Marine Grade Standard Battery Cable Assemblies are manufactured with Ancor's premium tinned copper battery cable and tinned copper lugs, available in red or black insulation and in a variety of lengths. Each lug end has a piece of Ancor's adhesive-lined 3:1 heat shrink tubing placed over the electrical connection to seal out moisture and provide strain relief — a thoughtful detail that extends connection life significantly.
Why Ancor Leads in Marine Battery Cable
Since 1978, Ancor has been setting the bar for high-quality electrical components explicitly designed for the demanding marine environment. Ancor is the originator of Marine Grade® wire, which is built with features such as UV resistant jacketing and individually tinned stranding. That heritage of innovation means boaters can trust Ancor battery cable to deliver the high-amperage reliability that starting an engine or powering an inverter demands — year after year, season after season.
