Copper Battery Clip for 40 A Testing

This copper clip pair handles up to 40 A for automotive battery and test lead connections. Each clip accepts wire up to 3/16 in and opens to a maximum jaw width of 5/8 in. The set includes one positive and one negative clip for immediate use. Screw or crimp termination secures the conductor without solder.

Replaces Worn or Undersized Test Clips

Swap out damaged clips that no longer grip battery posts or that overheat under load. The 40 A rating suits typical starter and charging circuits where lighter clips would melt. Upgrade when existing leads show pitted jaws, loose springs or insulation cracked from engine heat.

Fits Standard Battery Posts and Test Leads

The 2 7/16 in overall length and 11/16 in height clear most top-post terminals without crowding adjacent components. Copper construction resists corrosion and maintains low contact resistance over repeated connections. No special tools are required beyond a screwdriver or crimper for the wire attachment.

Questions about this item

What wire size does the 3/16 in jaw opening accept?

The copper jaws open to 5/8 in and grip wire up to 3/16 in diameter for a secure test or battery connection.

How do I attach the clip to the wire, and what step is often missed?

Fasten the wire with the supplied connection screw or crimp it; the step often missed is tightening the screw fully so the copper contact stays firm under 40 A load.

When should I replace the clip?

Replace the clip if the copper jaws show pitting, the spring loses tension, or the screw threads strip, as any of these will reduce the 40 A rating.
