Rechargeable battery holder(1 cell)

A 1-cell rechargeable battery holder is a plastic holder designed to securely hold one rechargeable battery, commonly a 3.7V Li-ion battery. It provides a safe and convenient way to connect the battery to an electronic circuit through its positive (+) and negative (−) terminals or wires. A typical 3.7V Li-ion cell has a nominal voltage of 3.7V and reaches about 4.2V when fully charged. These holders are commonly used in Arduino projects, small robots, LED circuits, sensors, and portable electronic projects.
