A 2 AA Battery Holder is device for holding and connecting two AA (Double-A) Batteries in series with a positive and a ground lead coming off of it. The positive lead has a Voltage of 3 Volts and the ground is at 0 volts. This pack also has a built in switch, which we find useful.

We use these battery holders in a lot of projects, since 3V is useful for powering 3v motors and most LEDs.
