Battery Holder for CR2032 with soldering tabs. Including Battery CR2032.
Some early 1900s battery holders were often no more than a cardboard box with copper contacts. By the 1920s, battery holders used twin metal clips (like fuse holders) to hold the battery in place while making electrical contact. Patent no. 1439429 was granted in Dec. 1922 for an assembly with two spring arm clips, a small switch, and a lamp assembly on the end of connected wires.
