A rechargeable battery pack is a type of battery pack that is able to be recharged and used multiple times. Rechargeable battery packs typically come in rechargeable lithium-ion or nickel-metal hydride (NiMH) varieties and are used in a variety of electronic products such as digital cameras, cell phones, portable gaming devices, and flashlights. Rechargeable battery packs can be recharged by plugging them into an outlet or via a USB cable. Rechargeable battery pack is more expensive than disposable batteries, but their ability to be recharged makes them much more cost-effective and eco-friendlier in the long run.
