Description

This four-cell battery holder is a durable plastic enclosure designed to organize and connect four standard batteries, typically AA or AAA cells, in a series arrangement to provide a higher total voltage for electronic devices. It features integrated metallic coil springs that maintain a secure electrical connection and allow for the easy insertion and removal of the batteries. The unit comes equipped with pre-attached, color-coded wire leads—red for the positive terminal and black for the negative—making it simple to integrate into robotics projects, DIY electronics, or classroom science experiments.
