Does the direction of emf provided by the battery depend on the direction of the current flow through the battery?

Within a source of emf ( like a battery) a chemical reaction occurs which moves the mobile charge carriers from a region where they have low electric potential energy to a region where they have a higher electric potential energy.(like water raised by a pump from lower gravitational potential to a higher gravitaional potential at the cost of electricity etc).

However, in the circuit when connected to a load, the current flows from higher potential to lower potential (like water flows from the water tank at the roof to the tape in the kitchen).

To summarize, the electric current flows from negative to the positive terminal in the outer load circuit while in the battery (source of emf) the current by positive ions flows from negative to the positive terminal at the cost of energy. Therefore, the direction of emf provided by a battery doesn’t depend on the direction of the current flowing through the battery.
