uxcell Copper Sheet Roll, Metal Foil Plate 1000mm x 100mm x 0.1mm

For small electronics repair of battery contacts, I had been using some copper tape that claimed the adhesive was also conductive, but it was either very poor or non-conductive and I usually had to use it folded over so it was all copper. I think copper tape can work in a pinch for testing, but to make the fix more permanent (like replacing battery contacts), I decided to go for some actual solid copper. I wasn't sure what thickness to get, but 0.1mm is plenty compared to how razor-thin the copper tape was. This allows the copper sheet to still be flexible, easy to cut with tin snips, and flexible but not rigid nor weak. It also looks much better than the crumpled/wrinkled look of the copper tape. For more permanent fixes, I'd recommend this copper sheet if you're fixing things like battery terminals for electronic devices.

There is not much to comment on this. It's copper, its good quality and its sturdy. Did not measure the length but the roll is heavy so there is decent amount of copper in there.
