Cartman 4AWG 37-Inch Negative Battery Cable – 1 Pack

Cartman 4AWG 37-Inch Negative Battery Cable is built for durability and easy installation in demanding environments. The conductor uses a 4 AWG copper core that balances flexible routing with reliable current capacity for most 12V electrical systems. The 37-inch length gives installers a comfortable working margin to connect distant terminals without forcing awkward bends or tension on the lug assemblies. It fits 3/8-inch studs, a common size on many battery trays, alternators, and chassis grounds, so you can often substitute this cable for worn-out or undersized options with minimal fuss. The tin-plated 95% copper lugs provide an extra layer of protection against corrosion and oxidation, helping maintain clean, tight connections under heat, humidity, and vibration. The copper used is SAE-grade copper, and the assembly is designed to stay flexible in extreme conditions—so you can route it through tight spaces without kinking. Rated heat tolerance up to 105 C, the cable remains pliable rather than stiff when the engine bay heats up, enabling smoother routing through tight spaces. The outer insulation is designed to withstand typical automotive or marine exposure, while the lugs are machined for a snug fit and dependable contact at the terminal. This is a practical, single-pack solution when you want a ready-to-install negative cable that blends safety, durability, and reasonable price.
