Understanding Primary and Secondary Batteries

The video tutorial explains the differences between primary and secondary batteries. Primary batteries, such as alkaline and manganese dry batteries, are single-use and cannot be recharged. Once they are fully discharged, they become unusable. In contrast, secondary batteries can be recharged and are used in various electronic devices like notebooks, tablets, and smartphones. These batteries support repeated use, making them essential in daily life.
