How many cells are typically required for the construction of a battery?

A battery consists of two or more electrochemical cells that convert chemical energy into electrical energy. While it is true that a single cell can function as a battery (for example, a standard AA battery is essentially a single cell), in most contexts, particularly when discussing batteries used in various applications, "battery" refers to a combination of multiple cells working together to increase voltage and capacity.

When more than one cell is connected, they can be configured in series to increase the voltage or in parallel to increase the current capacity. This is essential for many applications, from small electronic devices to electric vehicles, where higher power output is necessary.

Thus, stating that a battery typically requires more than one cell accurately reflects the common usage and understanding of what constitutes a battery in electrical and electronic systems.
