4x AAA Battery Holder Box, Without Cover

Product Overview
The 4 × AAA Battery Holder Box (no cover) is a compact, easy‑to‑wire enclosure that securely cradles up to four AA‑size alkaline or rechargeable batteries in a single series or parallel configuration. Designed for rapid prototyping, the open‑top housing lets students connect wires directly to the built‑in metal contacts, making it ideal for wiring experiments, robotics, portable electronics, and any project that needs a reliable, low‑voltage power source.

What Students Will Learn
Using this holder, learners explore fundamental concepts such as voltage, current, and series‑parallel circuitry; they practice safe battery handling, polarity identification, and solder‑free connection techniques with jumper wires or breadboard pins. The hands‑on experience reinforces problem‑solving skills as students design, test, and troubleshoot power distribution in their own STEAM projects.

Key Features

• Holds 4 AAA cells (1.5 V each) – up to 6 V total output
• Durable ABS housing with integrated snap‑on terminals for quick, tool‑free wiring
• Clear polarity markings on the contact pads to prevent reverse‑polarity errors
• Open‑top design for easy access to battery terminals and seamless integration with breadboards or perf‑boards
• Lightweight, compact (35 mm × 20 mm × 12 mm) – fits into any portable prototype

Why It’s Perfect for STEAM Education
Power is the backbone of every electronic invention, and this battery holder gives students a tangible way to experiment with it. By providing a reusable, low‑cost power module, learners can focus on creative design; building anything from simple LED circuits to motor‑driven vehicles, while reinforcing math (calculating voltage drops), engineering (designing robust connections), and technology (integrating with sensors and microcontrollers). The hands‑on, inquiry‑based nature of the product aligns perfectly with STEAM curricula, encouraging curiosity, iteration, and interdisciplinary thinking.
