This adorable little coin cell battery holder is great for small, portable, or wearable projects. It holds two 20mm coin cell batteries (also known as CR2032) in series to generate 6V nominal. 20mm coin cells are popular as they are used in keychain lights and remotes, so they are easy to get and fairly low-cost. They tend to have about 220mAh capacity. The housing is made of plastic and easily screws counter-clockwise to open and close.
Adafruit Industries ADA4988 2 x CR2032 Coin Cell Battery Box w/ On-Off Switch & Plain Wires
This battery holder is by far the easiest way to add a battery to a small wearable project. By coincidence, there are two small 1mm diameter holes in the metal connection tabs, just large enough for a #5 or smaller needle to pass through. One tab connects to common ground (negative) and the other tab is +3 Volts. This holder is meant to be used with Lithium CR2032 (20mm diameter, 3.2mm thick) sized coin batteries. These are almost always 3V at about 200+ mAh capacity.
