Battery holders, clips, and contacts are components used to securely store and power electronic devices. A battery holder is an enclosure designed to hold one or more batteries, and typically includes electrical contacts that allow the batteries to be connected to a circuit. Battery clips provide an even more secure and convenient way to attach and disconnect batteries from a circuit. These clips typically include spring-loaded electrical contacts that allow for easy installation, removal, and replacement of batteries. Finally, battery contacts provide an electrical connection between the battery and the circuit. These contacts are often made from metal and may be in the form of either a pin or a plug, depending on the application.
