Ancor 2 AWG Tinned Copper Battery Cable — 25 ft Marine-Grade, Ultra-Flexible, Corrosion-Resistant

Ancor 2 AWG tinned copper battery cable, 25 ft in red, is a marine-grade, ultra-flexible primary wire built to resist corrosion, vibration, and harsh environments.

This 25-foot length of Ancor 2 AWG battery cable combines fine tinned copper stranding and a durable vinyl jacket to give reliable power delivery on boats, RVs, and other mobile power systems. The tinned strands slow corrosion and electrolysis in wet or salty environments while the Type 3 ultra-flexible construction reduces fatigue from repeated bending and vibration. The proprietary insulation remains pliable in extreme cold and stands up to heat, chemicals, UV exposure and abrasion, making it a practical choice where durability matters.

How does this cable resist corrosion and marine conditions?

The conductor is made from many individual copper strands that are tinned to form a protective coating against oxidation and galvanic action. Tinning offers a barrier that helps maintain conductivity in saltwater, humid air and other corrosive settings without sacrificing flexibility.

• Tinned copper stranding for enhanced corrosion resistance
• Type 3 ultra-flexible construction reduces strand breakage
• Vinyl insulation resists salt water, battery acid and oil

What temperature and electrical ratings should I expect?

The Ancor wire’s insulation is engineered to perform across a wide temperature range and is rated for standard electrical use in marine applications. It carries a 600-volt insulation rating and withstands high temperatures when dry and lower temperatures when wet, meeting common industry requirements.

• 600 V insulation rating for primary wiring tasks
• 105°C (221°F) maximum dry temperature rating
• 75°C (167°F) maximum wet temperature rating

Is this cable easy to route and install on boats or vehicles?

The ultra-fine stranding classified as Type 3 makes the cable exceptionally flexible, so it routes smoothly around engine bays, through tight conduit, and across bulkheads. Its pliable insulation stays soft even in sub-zero conditions, making terminations and bending simpler for installers.

• Flexible for neat routing in constrained spaces
• Stays pliable to -40°F/-40°C for cold-weather work
• Compatible with common crimp lugs and connectors for battery connections

Does this wire meet marine and safety standards?

Ancor constructs this 2 AWG battery cable to exceed several recognized marine and electrical standards so it can be specified with confidence for many onboard systems. Compliance helps ensure the cable performs under regulatory scrutiny and typical marine stressors.

• Exceeds UL 1426 requirements for marine primary wire
• Meets US Coast Guard Charter boat regulations (CFR Title 46)
• Complies with ABYC standards for marine electrical systems

Who is this for: This 25-foot Ancor 2 AWG tinned copper battery cable is aimed at boat owners, marine electricians, RV enthusiasts and mobile-power technicians who need a durable, flexible power conductor for battery banks, starter circuits or heavy DC runs. If you require a cable that resists saltwater corrosion, handles vibration, and remains workable in extreme temperatures while meeting marine safety standards, this Ancor wire is a practical choice.
