    That EMG. circuit is rated for 18 volts so a 12 volt a23 battery is smaller than a 9volt. You'll need a battery holder for it. The holders are about 1.3” x .47 x .47”

    A good amount smaller. The 9v is 1.9” × 1.04” × 0.69”

    Find them on amazon

  2. Thanks, I was worried about the current specs but the a23 has 55 mAh enough for the 980 µAh required

    Multiply milliamps by 1000 to get equivalent microamps

    Amps aren't forced into a load, the load draws them from the source. Mah is a measure of what the souce can supply for one hour at that drain level 55mah. Double the draw and it’s good for a half hour.

    So even a 490 uah battery can run a 980uah circuit. For a half hour.

    In your case run time will be about 56 hours.
