If a plug is stereo, it will have three isolated contacts: tip, ring and shaft.  A mono plug only has tip and shaft, with the shaft area including where the ring would normally be on a stereo plug.  

If a jack is stereo, it will have three contacts as well, intended to make contact with the tip, ring, and shaft.

If you insert a mono plug into a stereo jack, the ring contact on the jack will make contact with the shaft of the plug.

If a battery ground wire is soldered to the ring lug on a stereo jack,  it is isolated from everything, and the battery is not "powered".  But once you insert a mono plug, that battery ground wire is now in contact with the shaft of the plug which is also connected to the pedal and circuit ground.

Plug in, and the battery is connected.  Unplug and the battery is disconnected.
