Batteries are usually divided into which two categories?

Batteries are typically categorized into primary cells and secondary cells based on their ability to be recharged. Primary cells are designed for single-use applications and cannot be recharged after their energy is depleted; they are commonly used in devices such as flashlights and remote controls. On the other hand, secondary cells are rechargeable and can be used multiple times, which makes them ideal for applications like smartphones and electric vehicles where regular recharging is feasible.

This distinction helps in understanding how different battery types function and their suitability for various applications. Knowing whether a battery is primary or secondary can guide users in selecting the appropriate power source for their devices and managing their energy needs effectively.
