Copper Battery Starter Lugs for Cable Terminations
Copper starter lugs crimp onto stranded battery cable to create a durable ring termination for starters, alternators, grounds, distribution blocks, and other high-current connections.
High Conductivity Copper body helps minimize voltage drop on high-amp circuits.
Heavy-Wall Barrel Deep barrel accepts fine-strand cable for strong mechanical and electrical crimps.
Cable-Friendly Entry Flared or chamfered mouth on many styles to ease cable insertion.
Stud Size Options Choose ring hole diameters to match common posts and hardware.
Finish Choices Plain copper or tinned copper styles used widely around moisture and marine environments.
Tool Compatible Works with indent, hex, or dieless crimp tools specified for the cable gauge.
How to Select a Starter Lug
Match the lug to your cable, hardware, and environment.
Choose the cable gauge (AWG) to match your battery cable’s size and strand class.
Select the stud hole diameter for the post, bolt, or bus bar you’re connecting to.
Pick barrel type/length (standard or heavy-duty) to suit current and pull-out needs.
Decide on finish: use tinned copper where added corrosion resistance is desired.
Confirm tooling—use the crimp profile and die size recommended for the cable and lug.
Common Applications
Automotive starter and ground leads
Marine battery and inverter connections
Winches, RV/solar battery banks, and power distribution blocks
Equipment grounds and chassis bonds
Installation & Safety
Strip to the correct length; avoid nicking strands and insert fully into the barrel.
Crimp with the specified die until the full profile is achieved; verify pull-out strength.
Seal with heat-shrink (adhesive-lined where needed) and route for strain relief.
Torque hardware to spec; use lock washers/nuts where vibration is present and protect from abrasion.
