I said I would do an electronics-based ScrapHappy because, you know, why not? This is a very simple thing but will be handy to, well, me because I build things from time to time that use these little coin batteries. They need a holder since soldering direct to them is pretty dangerous and makes replacement, well, pretty dangerous too.
So, all you need is a piece of insulating material (like cardboard, thin wood, or an offcut of plain stripboard like I have used here), a piece of stiff, uninsulated wire (an offcut from a component lead is what I used, about 2cms long) and a small bulldog clip (colour optional).
Put the ends of the wire through holes 0.5cm or so apart (long enough to provide a good base for the battery to sit on) and join the ends on the other side. These form your negative connection unless you put the battery in the other way up.
Then put the clip over as shown and remove the bottom handle (? Opening oojamaflip? Thing you press to open the clip). The top flippy-opener thing is the positive connection). Easy, huh?
Eh, voila! One battery clip for any number of coin cells from one to, oh I don’t know, let’s say three (actually, as many as will fit under the clip without pinging out at an inconvenient time).
