FAQs about Battery discharge current from positive to negative
Does current flow in a battery move from positive to negative?
No, current flow in a battery does not move from positive to negative. Instead, the flow of electric current is conventionally described as moving from the positive terminal to the negative terminal. Electric current is defined as the flow of electric charge.
What happens when a battery is discharged?
During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode.

But what happens inside the battery?
Why do electrons flow from negative to positive in a battery?
So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive. You might wonder why the electrons don't just flow back through the battery, until the charge changes enough to make the voltage zero.
Why does a battery have a negative charge?
This apparent contradiction arises from historical conventions in electrical engineering, which defined current flow based on the movement of positive charges. In reality, the internal chemical reactions within the battery generate an excess of electrons at the negative terminal.
