Non-rechargeable batteries, also known as primary batteries, are designed for single-use and cannot be recharged once depleted. They are commonly found in everyday devices such as remote controls, flashlights, and toys. These batteries provide a convenient power source but must be replaced once they run out of energy. The most common types of non-rechargeable batteries include alkaline, lithium, and zinc-carbon. Each type has its own advantages, such as longer shelf life or higher energy density. However, because they cannot be reused, proper disposal is important to minimize environmental impact and promote recycling efforts.
