Battery holder for 3xAA (4.5V)

The 4.5V output from this 3xAA holder is exactly what my DIY sensor project needed, and the lack of a pre-attached plug made it simple to wire directly into my circuit. The contacts hold the batteries firmly without being too stiff to insert.

I was a bit worried about finding a holder that fits snugly in my project box, but the compact size of this 3xAA unit is perfect. The terminals make solid contact, and the 4.5V output is exactly what I needed for my sensor circuit.

Finally got this for my breadboard project and the open terminals make wiring super easy. It holds the three AAs securely and delivers a steady 4.5V without any fuss.
