What Is The Difference Between Cell And Battery?

Cells and batteries are two devices that have provided us with a reliable source of energy and are used in virtually every aspect of our lives, from electronics to automobiles. Without batteries, we would not have been able to enjoy the convenience and comfort of modern life.

Although similar in some aspects, batteries and cells are different in some key areas.

A cell contains chemical energy sources such as gasoline, propane, or natural gas. To produce electricity, it transforms these sources into electrical energy.

On the contrary, a battery usually contains electrical energy already produced or that can be easily recharged.

Let’s look at the other differences between cells and batteries, but first, let’s define the two.

What is a cell?

A cell is a device that produces electricity through chemical reactions. It contains chemical energy, like natural gas, and converts available resources into electrical energy.

Each cell has two terminals, namely:

  • Anode: An anode is the terminal from which current enters and leaves.
  • Cathode: The cathode is the terminal through which the current exits.

There are several types of cells, such as primary, galvanic, electrical, fuel, solar, etc. The cells are mainly used in watches, toys, remote controls, etc.

What is a battery?

A battery is a device made up of one or more cells that convert the chemical energy contained in them directly into electrical energy. It is a set of interconnected cells that can produce an electrical current. In most cases, the cells are arranged in series and parallel configurations to provide the desired voltage and current output.

There are mainly two types of batteries:

  • Primary: Batteries that are not rechargeable.
  • Secondary: Batteries that are rechargeable.

Batteries also have two terminals: anode and cathode. They are mainly used in electronic appliances and equipment, such as flashlights, mobile phones, laptops, cars, etc.

Difference between cell and battery



Single-unit device that transforms chemical energy into electrical energy.

A collection of cells.

It can be classified as reserved, wet or dry depending on the electrolytes used.

It can be classified as a primary or secondary battery, depending on whether it can be recharged.

Small and compact in size.

Larger and more voluminous in size.

Provides power for shorter periods of time.

Provides power for longer periods of time.

Typically used for simpler, lower energy tasks.

Typically used for heavier tasks.

It is used in portable and less energy-intensive objects, such as watches and lamps.

It is used in devices that require more power, such as vehicles and electronics.
