Geosiry 2 Gauge Battery Cable – 15FT Red + 15FT Black OFC Welding Cable for Automotive, Solar, Marine

Overview

Geosiry 2 Gauge Battery Cable combines two 15-foot runs of premium oxygen-free copper wire with a rugged EPDM insulating jacket, built to withstand demanding environments. Designed for high current DC systems, this cable balances conductivity, flexibility, and resilience, making it a versatile choice for automotive, solar, marine, and generator setups.

What makes it stand out

• Premium Fully Annealed Oxygen-Free Copper Wire for excellent conductivity and easy routing
• 1070 strands of 0.2 mm copper provide a strong core with high flexibility
• EPDM insulating jacket offers heat, moisture, abrasion, oil, and chemical resistance for outdoor use
• Rated up to 600 volts and operational from -122 F to 221 F

Durability in real world use

• Fireproof polyolefin outer layer adds an extra safety margin in harsh environments
• Low impedance copper reduces voltage drop in DC high current runs
• Outdoor and marine readiness with robust insulation and solvent resistance

Why oxygen free copper matters

Choosing oxygen-free copper helps minimize resistance and heat buildup, supporting stable power delivery in dense wiring layouts such as engine bays and off grid installations.

Ideal applications

Use this cable for automotive battery connections, solar power arrays, marine systems, and generator wiring where clean, dependable power delivery matters.

Package, care, and tips

The kit includes red and black conductors, each 15 feet long, with care guidance and after sales support from Geosiry. On arrival, verify packaging and inspect the insulation for transport damage. For best results, keep bends smooth, avoid sharp edges, and store away from extreme heat. Ensure connectors and lugs are rated for the current and temperature you plan to run.
