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. Comes with an on-off switch and 12" long plain wires on the end, for easy attachment or soldering to whatever circuitry you wish to power.

We also carry a similar 2 x CR2032 coin cell battery holder but with a JST connector which has the two batteries side-by-side for a slimmer (but longer) package.
