Batteries are primarily divided into which two categories?

Batteries are primarily divided into two categories: primary cells and secondary cells. Primary cells are designed for single-use, meaning they cannot be recharged after their energy is depleted. Common examples include alkaline batteries, which have applications in devices such as remote controls and flashlights.

Secondary cells, on the other hand, are rechargeable batteries that can be used multiple times. When the energy stored in these cells is depleted, they can be recharged and used again. Examples of secondary cells include lead-acid batteries used in cars and lithium-ion batteries found in portable electronics.

This division is critical for understanding battery technology because it informs users about the applications and limitations of different types of batteries, affecting choices in device design and energy management.
