2 x AAA Battery Holder Box

Dual AAA Cell 3V DC Output: Cradles two micro AAA (1.5V) batteries in series to supply a steady 3V power rail for compact microcontrollers, wearers, low-power IoT nodes, and small LED devices.

Pre-Stripped Color-Coded Wire Leads: Features pre-attached red (positive) and black (negative) flexible copper lead wires, enabling effortless soldering onto PCB pads or direct connection to breadboard headers.

Compact Low-Profile Footprint: Ultra-lightweight and space-saving open-frame design engineered specifically for micro-electronics where mounting real estate and minimal weight are critical.

High-Tension Coil Spring Contacts: Nickel-plated steel spring terminals maintain continuous positive pressure against AAA battery contacts, eliminating power dropouts during physical motion or vibration.

Molded Polarity Identification: Clear positive (+) and negative (-) symbols embossed on the internal base floor prevent accidental reverse insertion and guard downstream components against circuit damage.

Integrated Screw Mounting Holes: Base tray includes pre-drilled countersunk mounting holes for clean, secure attachment to custom enclosures, project boxes, or small robot frames.

Body Material: High-impact, durable black ABS plastic.

Terminal Material: Nickel-plated steel spring contacts with color-coded copper lead wires.

Technical Specifications:

Cell Support: 2x AAA Batteries (Series configuration, 3V nominal).

Lead Wire: Approx. 15cm color-coded insulated lead wires.

Color: Matte Black.

Usage Advice: Double-check polarity markings before connecting wire leads to delicate low-voltage circuits.

Maintenance: Keep spring contacts clean and dry; wipe with a soft cloth or isopropyl alcohol if dust builds up

Essential Ultra-Compact Power Pack: Position as an indispensable micro-power supply for wearable tech projects, small remote controls, STEM classroom kits, and compact microcontroller builds.

Highlight Space-Saving Footprint & Pre-Wired Convenience: Emphasize how its ultra-compact AAA form factor offers a lighter, smaller alternative to standard AA holders while maintaining full 3V power.

Recommended Cross-Sell Add-ons: Pair with 2 X AA Plastic Battery Holder, 3 x AAA Battery Holder Box, 4 x AAA Battery Holder Box, and ESD antistatic mat 50x40CM PCB Welding Mat.
