Product Overview
Flat open-frame holder for four AAA (UM-4 / R03 / size 24) cylindrical cells wired in series, delivering 6.0V DC nominal with standard 1.5V alkaline cells or 4.8V DC nominal with 1.2V NiMH rechargeables. Red and black wire leads connect directly to a load circuit. Two screw-mounting holes through the base allow permanent installation in a project enclosure. Model: UM-4X4-flat.
Key Features
- Battery size: AAA / UM-4 / R03 (1.5V per cell)
- Cell count: 4 cells, flat side-by-side layout
- Output: 6.0V DC nominal (alkaline) or 4.8V DC nominal (NiMH rechargeable)
- Connection: Bare red (positive) and black (negative) wire leads
- Contacts: Coiled steel spring contacts (negative), gold-tone flat button contacts (positive)
- Housing: Black ABS plastic with molded 1.5V polarity markings per slot
- Mounting: Two integrated screw holes through base
- Open-frame design - no cover or integrated switch
Applications
- Powering an Arduino or microcontroller project from a regulated 6V supply without a bench power supply in the loop
- Dropping into a robotics chassis to run drive motors or servo rails during prototyping before a dedicated battery pack is spec'd
- Mounting inside a cosplay prop or LED costume piece where flat profile and screw holes make a permanent, flush installation practical
- Replacing a dead internal pack in a vintage toy, walkie-talkie, or handheld device that originally ran on four AAA cells
- Wiring into a breadboard experiment or Raspberry Pi Pico project for portable power without modifying a commercial battery box
Frequently Asked Questions
Does this holder include batteries?
No. The holder accepts four standard AAA cells; batteries are not included.
What output voltage should I expect?
With four 1.5V alkaline AAA cells wired in series, nominal output is 6.0V DC. With four 1.2V NiMH rechargeable AAA cells, nominal output is 4.8V DC.
How do I connect the wire leads to my circuit?
The red lead is positive, the black lead is negative. Ends are stripped and ready to solder, splice, or terminate with a connector of your choice.
Can I permanently mount this in an enclosure?
Yes. Two screw holes molded into the base allow direct panel or chassis mounting.
Is there a cover or on/off switch?
No. This is an open-frame holder. It does not include a slide cover or integrated switch. Batteries are exposed once inserted.
Four cells, one flat footprint, six volts ready to go - whatever you are building, the power side just got simpler.
