Review on Uxcell Negative Conversion Nickeling 16 5Mmx16Mm by Sharon Payne

I found a link to them with a battery holder for things (for 3D printing) and recommended them. I've used many of them since then and love them more than any holder you can buy. They are soldered to the terminals. In my application they need a little help to hold them in place so I bend them in slightly (I mean SMALL) and they snap like a rock and work great. I use them in large charging arrays and plug and unplug batteries as often as the chargers can fill them, they work great!
