The voltage (cell potential) of a dry cell is approximately 1.5 V. Dry cells are available in various sizes (e.g., D, C, AA, AAA).All sizes of dry cells comprise the same components, and so they exhibit the same voltage, but larger cells contain greater amounts of the redox reactants and therefore are capable of transferring correspondingly greater amounts of charge.
Batteries are valued as devices that store chemical energy and convert it into electrical energy.

Importantly, the Gibbs energy reduction …
The key difference with a real battery is that the voltage across its real terminals depends on what is connected to the battery.
