Inside of battery-operated devices requiring the batteries to be stacked end-to-end, how come the batteries in the middle don’t quickly neutralized when the electrons from the negative cell flow through the positive?

Question

For anyone that doesn’t know, and I hope I’m not relaying incorrect information, a regular voltaic battery like a Duracell or Energizer has a negatively charged end where electricity flows through the device it’s being used for, powering the device, before completing its circuit to the positively charged end and the charges cancelling out/neutralizing. The battery is dead when the there’s little to no charge difference between the cells.

When batteries are stacked end-to-end in like a flashlight, won’t the negatively charged ends in the middle flow through the positive end of the next battery? Why aren’t they more quickly neutralized then?

Answer 1

when the cells are connected they act like one bigger battery. the electrons still move from negative to positive even through other cells. the overall effect is that the last negative end is that much more negative than a single cell.
