Higher voltage than a fully charge battery can supply, when applied to the
battery terminals drives the chemical reaction and changes it from
releasing electrons to storing electrons but does not reverse the current as most
dumb engineers claim.

Oh? So how come the little arrow marked "I" (current) has changed
direction between the third and fourth pictures?
