Forney 54727 Battery Tune Up Clip, 50-Amp

I purchased these to attach to the cables on an inverter for my truck. They are ok and did the job, but could probably use a little improvement. It has a very soft clamping mount to put your wire into and you're supposed to clamp down on the wire with the copper crimp, however the size of the crimp was pretty small and it's very soft so I felt it necessary to break out the soldering iron and make it a bit more industrial. Also, the clamp teeth are sort of cockeyed, but in reality it's more of an aesthetics issue and I don't think it would affect it's operation. The spring seems sturdy enough and I expect it will hold up for quite some time.

My old clamps literally broke at the hinge. These new replacement clamps look like they are riveted better but they have a cheap feel to them. Time will tell how they hold up. I've held nicer clamps before that's how I gauge these to be inferior

The gigantic clips that came with my battery charger broke, and I used these smaller ones as a replacement. They work perfectly well, no need for gigantic ones (they can handle the 10 amps with no problem). Best to solder them, not just crimp, but they do have the crimp capability if you don't want to solder. Not sure if they would overheat at 10 amps without solder...

These are stronger than they lookThey are not well formed but for the price "well formed".The copper plate is good and easily soldered when making the electrical bond after power crimping to make a mechanically strong connection. SOLDERING WIRES 101.Best of all they are Cheap.These things are always subject to abuse and you have a choice of wire strength or clip strength and in this case the clip might win

I got what I expected, worked great for my battery charger.

just what I was looking for!

These are quite weak at the wire crimp location. I soldered them as well. They'll do the trick for my small charger.

Cheaply made. Not quality I was expecting from Forney.
