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 really like thes....They look copper plated They have a strong bite. I attach these to my rv batteries and then i have plenty of space to add any charging clips or accesssories to my batteries. if i get a little corrosion i just give them \ a spin and it gets a new bite of fresh contact metal.

These are replacements for my battery charger. They work great.

Product was exactly as described. Nice, durable clamps. Rubber handle covers aren't the best, but the clamps themselves are exactly what I was looking for. There is good tension from the spring, and the teeth are strong enough to make a good connection on the battery post. Included wire eyelets and bolts/nuts for securing the eyelets/wire to the handles.

Clamps are exactly what we expected, nice and heavy construction, seen that hold 500A, excellent for our invents for safety connections in our projects.... We are so happy and recommend it 100%

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.

They are okay but not big enough to put a heavy duty wire on. The hardware that was sent was subpar and wasn't properly stamped so a screwdriver will fit to tighten it up. I'll keep them but wish I had known before I purchased

Works great

Great price easy to assemble
