Automotive battery cable 4 AWG

This 68 in black cable connects a battery to a starter using flattened copper lugs. It is built for 12 V systems and rated for up to 400 A. The PVC insulation resists water, grease, sunlight and abrasion. It meets RoHS and SAE SGT standards.

Replaces worn or undersized starter leads

Swapping out corroded or thinner gauge wire restores full cranking current to the starter motor. The 4 AWG conductor reduces voltage drop compared to smaller cables. The jump is worth it when slow cranking or heat at the terminals signals excessive resistance.

Sustained load performance

Copper lugs and PVC jacketing maintain conductivity at up to 140 Degrees F. Resistance properties protect against degradation from engine bay contaminants. The cable handles continuous high-current demands during repeated starting cycles without overheating.

Questions about this item

What stud size does the flattened lug on this 68 in cable fit?

The flattened lug is designed for a 5/16 in stud size to connect the switch-to-starter circuit.

How do you install the pre-crimped lugs on this 4 AWG battery cable, and what step is often missed?

Route the 68 in cable, bolt each lug to its terminal, then tighten to spec; the step often missed is cleaning the terminal faces before tightening.

When should this PVC-insulated 4 AWG cable be replaced based on its 140 °F temperature rating and resistance properties?

Replace it if the insulation shows cracking, grease swelling, or heat damage beyond the 140 °F rating, or if water and abrasion resistance are compromised.
