This battery case holds 6 AA batteries and connects them together in series. The output voltage with 6 standard AA batteries will be approximately 9VDC. The case has 150mm / 6” wire leads with a 2.1 x 5.5mm DC Barrel Jack on the end. These are an ideal replacement for a 9V battery when only AA batteries are available.

There are 2 mounting holes on the case for attaching it to your project; alternatively a good double sided tape could be used on the smooth back.
