Heavy Duty Crocodile Clamp Thicken Pure Copper 100A/800A/1500A Car Battery Charger Clamps Power Replacement Battery Alligator Clips Jumper Cables Clamp Welding machine clamp（500-1500A）-Large

I bought these to replace old broken battery terminal clamps. The bolts They supply work perfectly, and the rubber covers are very practical.

Quality and durable. Perfect replacement for old clamps. Worked perfectly and so easy to install.

These clamps are small

I have a TrekPow 2500A that I bought a little over a year ago. This summer I had to use it several times to jump a boat battery one weekend. The second time of ever using the jump pack the negative clamp snapped. Not surprising as they are mostly plastic. The power unit is great but the clamps should be solid metal. These clamps are perfect for the TrekPow as they are almost identical in size so they fit perfectly in the TrekPow case. Installation was simple and these certainly are much better built than the plastic clamps. Highly recommended for this use case.

Very sturdy, heavy duty,good quality

These may be ok for small inverters, occasional light 12v hookups, but thats about it. 1/4" hole with screw and nut to fasten wire and lead into. Had to redrill 1/4" hole in clamp to a 3/8" just so a decent size wire could be attached to it and not 100amp like claimed.

Purchased to replace broken clamps on battery charger. These are not for full fledged battery jumper cables, but will work well for battery chargers under around 50 amps. Good spring tension. Appearance of brass except for spring. Insulated. All installation hardware and connectors included. Straight forward installation. Would purchase again.

The set of clamps is all metal, very sturdy.I used the set of clamps to replace the broken one (plastic) of my jump start battery pack. Very simple easy job.The wires are gauge 6. I think gauge 4 would be very very tight.

Very nice set of battery charger clamps.They should do the job well.
