Batteries Non-Rechargeable (Primary)Non-rechargeable batteries, also known as primary batteries, are batteries that are designed to be used once and then disposed of. They are commonly used in small electronic devices and other applications where a reliable power source is needed but rechargeability is not necessary. Non-rechargeable batteries are available in a variety of sizes and types, including alkaline, zinc-carbon, and lithium. These batteries are a convenient and widely-used power source, but they can also be a source of waste and pollution if not disposed of properly.
