Step 2: Placing the Button Cells
First, grab a piece of electrical tape--just a tiny piece, enough to double side and fit snugly attached to the battery.
Next, use the piece of electrical tape and "loop" it so that both sides are sticky.
Stick it to any side of the button cell and place it in the battery compartment--with the negative side of the button cell touching the spring of the battery compartment.
Repeat these steps for the second battery compartment.
*The negative side is the side without writing!*
