Product Description 

These plastic D-cell battery holders are designed for quick and flexible series connections in classroom and laboratory environments. Each holder features interlocking tabs that allow multiple units to be snapped together, enabling students to easily build higher-voltage power sources for circuit experiments.

Color-coded positive and negative terminals with knurled knobs provide fast, secure wire connections while helping reinforce correct polarity during setup. The modular design allows each holder to be used individually or combined with additional units depending on the requirements of the experiment.

These holders are ideal for hands-on instruction in electricity and circuits, supporting a wide range of activities from basic circuit construction to more advanced investigations involving voltage and power.
