2 x AA Battery Holder with Alligator Clips, Cover, and Switch - 3V

The most classroom-ready 3V power supply you'll ever clip onto a circuit.

This enclosed two-cell AA battery holder is the upgraded, polished cousin of the open-frame variety — featuring a snap-on protective cover that keeps your batteries secured and shielded, making it ideal for field trips, science camps, and any situation where projects get handled repeatedly by enthusiastic young scientists. The built-in ON/OFF slide switch means students can control their circuit without disconnecting a single clip, turning it into a natural teaching tool for the concept of open and closed circuits. Pre-soldered 6 inch (15.2 cm) red and black leads with color-coded alligator clips make connecting to motors, LEDs, buzzers, or any other component completely tool-free and intuitive.

The sleek black closed-box design keeps everything tidy and professional-looking — a big plus for science fair presentations and demonstration setups where aesthetics matter as much as function. At 3V output with two AA batteries wired in series, it pairs perfectly with our Type 130 and 260 DC motors for a self-contained, clip-and-go motor circuit that anyone can build in under a minute. Durable enough for classroom wear and tear, compact enough to fit in a project kit bag, and versatile enough to power virtually any low-voltage experiment, this is one of those components you'll want a whole drawer full of.
