That's a difference in electrical potential, not potential energy.
It's described in units of "volts".
im not sure how clearly your phrasing your question, but when dealing with circuits potential difference (voltage) is max, and at the positive terminal its zero. it decreases as you go around the circuit. hope this helps
Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,
What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.
plus is the positive terminal (cathode) minus is the negative terminal (anode)
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

The difference in potential energy between the positive and negative terminals of a battery is expressed in volts.
The driving force for the flow of electrons in batteries is the potential difference, or voltage, created between the positive and negative terminals. This potential difference causes the electrons to move from the negative terminal (anode) to the positive terminal (cathode), creating an electric current.
The positive + terminal is slightly larger.
Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.
A battery has a potential difference between its terminals due to a build-up of charge separation (positive and negative terminals). This potential difference can act as an electron pump by causing the flow of electrons from the negative terminal to the positive terminal through an external circuit, thereby generating electrical energy.

The driving force for the flow of elections in batteries is the difference in electrical potential between the positive and negative terminals. This potential difference, known as voltage, creates an electric field that causes electrons to flow from the negative terminal to the positive terminal, generating an electric current.

The driving force for the flow of electrons in batteries is the potential difference, or voltage, between the positive and negative terminals. This potential difference creates an electrochemical gradient that pushes electrons from the negative terminal (anode) to the positive terminal (cathode) through an external circuit, allowing for the flow of electric current.
