Rechargeable Batteries refer to a type of battery that can be recharged and reused multiple times before replacing them. They are known for their ability to provide reliable and long-lasting power in portable electronic devices. Rechargeable Batteries come in various types and sizes, including nickel-cadmium (NiCd), nickel-metal hydride (NiMH), and lithium-ion (Li-ion) batteries. They are commonly used in electronic devices such as digital cameras, flashlights, remote controls, and cordless phones. Rechargeable Batteries are cost-effective and environmentally friendly compared to disposable batteries, as they reduce waste and save money in the long run. They are a convenient and versatile power source that can be charged using a power outlet or USB port, depending on the type of battery.
