When connected in a circuit, does current flow inside a battery. If yes, in which direction?

1$\begingroup$ We call them "circuits" because the current flows in (unbroken) circles. $\endgroup$– John DotyCommented Jun 29, 2022 at 15:21

$\begingroup$ Without continuous current, the formed charge disbalance would very quickly form potential countergradients, ceasing any external current. As hydraulic analogy, the cell chemistry is like a water pump, forcing continuous water current through closed tube circuit, or keeping different water levels if the tube circuit is open. $\endgroup$– PoutnikCommented Jul 4, 2022 at 13:52

Yes. When a battery is operating normally then current flows inside the battery from the negative terminal to the positive terminal.

1$\begingroup$ If it flows from the negative terminal to the positive terminal, then isn't the battery supposed to last forever as the charge difference between the positive and negative terminals don't change? $\endgroup$– SaynCommented Jun 29, 2022 at 17:13

2$\begingroup$ @Sayn, there are chemical reactions going on between the electrodes and the dielectric to support this current. When the reagents for these reactions are exhausted, then the reaction can't continue, the current stops, and we say the battery is "dead". $\endgroup$ Commented Jun 29, 2022 at 17:23
