Introduction: Button Cell CR2032 Battery Holder.

About: Transistors may sometimes work nice as firecrackers.

So i got loads of these CR2032 button cell batteries for small projects, and i was tired off always needing to use two fingers to test my circuits, by holding the + and - wires manually to the battery.

So i figured out i'd come up with a fast, effective, and easy way to make battery holders for these batteries.

Here's a list of what you will need:

  • soldering iron
  • PCB proto-board
  • Copper wires or similar

Step 1: Stripping Cables.

To get the copper wires i needed i just stripped some cables, You could use something stiffer than those i used but with some soldering and the right construction they wont fall out of place, i do not think i would use anything thinner than i did in this instructable.

Step 2: Cutting and Soldering.

I put the battery onto the PCB, just to get a picture of how big it was.

Note!: you need space on the sides of the battery, big enough to stick copper wire straight down.

Then i cut some copper wire, this pictures show's the minus side of the battery ( the minus pole / anode ).

i found that the anode was 4 x 4 holes big, so i put copper wires in a "4 x 4 holes" area.

Step 3: Connecting Cathode & Finish.

Since we "Measured" the size of the battery in the previous step, we now have connection with the Anode and the PCB, now we need put the battery on top of the Anode connection, to see where we need to stick the rest of the copper cables, i chose to put 1 straight over as shown in the picture.


  • You need to cut the connections between Anode and Cathode ( + and - ), or else you got a short circuit.
  • when working with Protoboard PCB's always check which way the connections go.
