2PCS Power Replacement Battery Alligator Clips Jumper Cable Clamps Welder Clips Crocodile Heavy Duty Clamps Pure Copper 500A Car Battery Charger for Automotive Car Vehicle Boat

These heavy‑duty 500A copper clamps feel solid and deliver a strong, reliable connection for battery chargers, jump starters, and general automotive use. The grip strength is excellent, and the pure copper jaws provide good conductivity without heating up. They work well on cars, boats, and other 12V setups, and the size makes them easy to attach even in tighter spaces. The only reason for 4 stars instead of 5 is that the springs are a bit stiff out of the box, so it takes a little extra effort to open them fully. Once they loosen up with use, they perform great and hold firmly without slipping. Overall, a dependable set of clamps — durable, conductive, and well‑built for automotive or workshop use with just a small break‑in period.

These are decent battery clips. The metal is pretty soft, which is good and bad. It's good because it makes it easy to crimp and connect wires, and seems to grip well. It's bad as it's easy to deform the jaws. The plastic/rubber sleaves are easy to slide off to allow you to attach these to wires. For the money, these are a good option if you want spares or need to replace damaged clamps.
