Common Battery Sizes and Applications

Batteries are a standard item in homes and workplaces, coming in various sizes and shapes for different purposes. The battery size determines the voltage and current it can provide. Here are some of the most common battery sizes:

AA Batteries:

AA batteries are highly popular and are suitable for applications that don’t require a significant amount of power. They have a standard voltage of 1.5 volts. These double-A batteries are the most common type of rechargeable battery, used in devices such as toys, cell phones, computers, digital cameras, audio recorders, calculators, radios, clocks, remote controls, flashlights, and even thermometers.
