  ... and the electrons are released the electrons compelled to move towards the lead oxide plate ...


I think that you are forgetting that the route to the positive plate is through the load connected to the cell or battery and not through the cell itself.

For electrons to go into the top of BAT2 electrons must come out the bottom and into the top of BAT3, etc.
