Potential Energy of a Battery?

There is a 12 \rm V potential difference between the positive and negative ends of the jumper cables, which are a short distance apart. An electron at the negative end ready to jump to the positive end has a certain amount of potential energy. On what quantities does this electrical potential energy depend?

the distance between the ends of the cables

the potential difference between the ends of the cables

the charge on the electron

the distance and the potential difference

the distance and the charge

the potential difference and the charge

the potential difference, charge, and distance

Update:

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. There is now a negative ion with a charge -2e at this terminal. What are the electric potential and electric potential energy of the negative ion relative to the electron?

The electric potential and the electric potential energy are both twice as much.

The electric potential is twice as much and the electric potential energy is the same.

The electric potential is the same and the electric potential energy is twice as much.

The electric potential and the electric potential energy are both the same.

The electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
