The 1-Slot AA Battery Holder Without Cover is a simple power holder for one standard AA battery. It is useful for small electronics, science projects, circuit testing, toys, LED projects, and basic DIY builds. The open design makes it easy to insert and remove the battery. Metal contacts on each end help hold the battery securely while creating a stable electrical connection. Attached wires can be connected to a circuit board, motor, LED, switch, or other compatible device. The holder is made from black plastic with metal contact parts. Its compact size makes it easy to fit inside small project boxes, models, and custom enclosures. The listed dimensions are about 58 × 16 × 16 mm. A single AA battery usually provides about 1.5V, depending on the battery type. Always check the voltage and power needs of your project before making a connection. Follow the correct positive and negative wire polarity to prevent circuit problems. Since this model has no cover, the battery remains easy to access. It is best installed in a dry area where the battery will not be exposed to water, dirt, or loose metal objects. This battery holder is a practical choice for students, makers, repair work, and quick circuit tests. It provides a clean and simple way to connect one AA battery without soldering directly onto the battery terminals.
