$begingroup$ ''amperage'' is an evil, evil word for ''current''. Although I suppose voltage is also an evil yet alluringly bisyllabic word for ''potential difference''. I guess everyone can call them what they like, but I find ''current'',''potential difference'' and ''power'' to be far nicer from a self-description perspective and more helpful in getting an intuitive feel for their interrelation.

6 FAQs about [Relationship between battery negative pole and current]
Does current flow from positive to negative in a battery?
Current flows from negative to positive in a battery. Electrons flow from positive to negative in a circuit. The conventional current direction is always the same as electron flow. Battery usage is the same in all electronic devices. Understanding these misconceptions is essential for grasping basic electrical principles.
Why is there a difference between a positive and negative battery?
The reason why is because the voltage potential difference - the "excess holes on the positive end" and the "excess electrons on the negative end" - is relative to a given battery. There are excess electrons/holes on the ends of a given battery with respect to each other.
Why does a battery have a negative electrode?
Due to this chemical process, there are more electrons in the negative electrode than in the positive one. This of course creates an electric field between the two battery terminals, resulting in a voltage between them, which can be used by an attached load.
Does the current flow backwards inside a battery?
During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm’s law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential.
What is a positive pole of a battery called?
The direction of flow of electricity in an electrolytic cell is the opposite from the flow when a battery is being used to power an external circuit, and the roles of the two poles or electrodes are reversed. Thus some writers will refer to the positive pole of a battery as its “cathode”.
Why does a battery Flow in the opposite direction?
This means that while electrons move from the negative terminal to the positive terminal inside the battery, the applied current is considered to flow in the opposite direction. This statement is incorrect.
