LABARAIN 2 AWG 22in Negative Battery Cable Black, Negative (17mm Terminal) with 10mm Lug, Tinned Copper

LABARAIN's 2 AWG Negative Battery Cable is a 22-inch, heavy-duty ground and inverter lead with tinned copper lugs and a 17mm brass negative terminal for reliable, low-resistance connections.

This 22-inch negative battery cable is built for demanding electrical setups where a short, rugged ground or inverter link is needed. It combines a pure copper core and tinned copper terminals with a brass negative connector and double-ended heat-shrink insulation to deliver steady current flow, corrosion resistance, and protection from moisture and abrasion. Designed for automotive, marine, RV, solar, and inverter systems, the LABARAIN cable supports grounding, battery extensions, and parallel battery connections while fitting most common battery posts.

How does this cable maintain low resistance and long-term conductivity?

The LABARAIN cable uses a pure copper conductor and tinned copper lugs to ensure minimal voltage drop and consistent conductivity under load. Tinning the lugs improves corrosion resistance, while the brass 17mm negative terminal provides a reliable metal-to-metal contact that fits most vehicles.

• Pure copper core for excellent conductivity
• Tinned copper lugs to resist oxidation
• 17mm brass negative terminal for secure contact
• 2 AWG thickness suited for high-current paths

What protective features keep the cable safe in harsh environments?

This negative battery cable is finished with polyolefin heat-shrink tubing at both ends and a full PVC outer jacket to guard against moisture, oil, and abrasion. The heat-shrink seals the terminal crimps and blocks contaminants, while the PVC insulation adds heat and chemical resistance for longer service life.

• Dual polyolefin heat-shrink at each end for sealed connections
• Durable PVC jacket resists heat, oil, and wear
• Crimped and tinned lug assemblies reduce entry points for corrosion
• Designed to perform in automotive, marine, and outdoor use

Will this cable fit my battery, inverter, or grounding setup?

The LABARAIN ground cable is 22 inches long and features a 10mm lug plus a 17mm negative battery connector that accepts 8–10mm screw posts, making it compatible with the majority of consumer and light-commercial battery posts and inverter terminals. Its length and connectors are ideal for short extensions, parallel battery links, or replacing worn factory ground leads.

• 22 in (≈55 cm) length for compact installations
• 10mm lug for secure bolted connections
• 17mm negative terminal fits common battery posts
• Works with automotive, RV, boat, inverter, and solar systems

How can I use this cable safely and effectively in different systems?

Install the cable by ensuring clean, tight contacts and properly crimped or bolted connections; use the heat-shrink ends to keep moisture out after fitting. For parallel battery setups, match cable gauge and length across batteries to balance loads, and always disconnect power sources before working on battery circuits.

• Clean battery posts and torque connections securely
• Use for grounding, inverter negative, or parallel battery links
• Keep cable routing clear of moving parts and heat sources
• Disconnect power before installation for safety

Who is this for: The LABARAIN 2 AWG 22-inch negative battery cable is designed for vehicle owners, RV and boat enthusiasts, solar installers, and anyone needing a short, dependable ground or inverter lead. It suits DIYers replacing worn ground leads and professionals building compact battery banks or inverter connections that demand low resistance, corrosion resistance, and robust environmental protection.
