Jar of Fireflies

Step 13 Preparing and Attaching the Battery Holder

Take the wires that you're going to use to attach the battery holder with and cut them to length. I tend to use the following lengths:

Red Wire: 2"
Green Wire: 2 3/8"

Strip a little bit off both ends of the wires and solder one end of the wire to the battery holder and the other end to the circuit board, being careful to get the polarities correct. Check the illustrations for details.

Also, once you have soldered the wires to the battery holder, you may want to snip the pins on it short so its not quite as awkward to attach to the lid of the jar.
