Semantics and an honest mistake explained in the post above. Here is a cut
and paste for your edification.
***************
Thanks for pointing out that inconsistency. My bad.
Semantics again, but you are correct. I should have said some of the electrons
flowing through the circuit (external) will drive the chemical reaction in the
discharged battery so it's state of charge will be increased.
Even though the positive and negative poles are on opposite ends of an AA
cell, electricity does not really flow through from end to end as there is
no internal circuit as such - just chemical reactions as in a lead/acid battery.
But let's not miss the point by pointing out semantics discrepancies. The fact
is the discharged cell will take on some charge from the circuit. The same
goes for two 12v lead/acid batteries in a circuit.
