Secondary (Rechargeable Cells)

Secondary batteries, also known as rechargeable batteries, are used to store electrical energy. They can be recharged by passing an electric current through them, and they can then be used to power devices again. Secondary batteries are used in a wide variety of applications, including portable electronics, power tools, and electric vehicles.

There are two main types of secondary batteries: lead-acid batteries and lithium-ion batteries. Lead-acid batteries are the most common type of secondary battery, and they are used in a wide variety of applications. Lithium-ion batteries are a newer type of secondary battery, and they are becoming increasingly popular due to their high energy density and long lifespan.

Secondary batteries are a valuable technology that allows us to store electrical energy for later use. They are used in a wide variety of applications, and they are becoming increasingly important as we move towards a more sustainable energy future.
