Batteries & Charger

Batteries are portable energy storage devices that provide power to electronic devices by converting stored chemical energy into electrical energy. They come in various types, such as disposable (alkaline) and rechargeable (NiMH, Li-ion), and sizes like AA, AAA, and 9V.

Battery chargers are devices used to replenish the energy in rechargeable batteries by supplying electric current. They vary in type, from simple plug-in units to smart chargers with advanced features like overcharge protection, fast charging, and compatibility with multiple battery sizes.
