This compact 2×2 AA battery holder connects four AA batteries in series, providing a nominal 6 V DC output (alkaline) or 4.8 V DC (rechargeable NiMH). The premium jumper header wires plug directly into a breadboard — no stripping or soldering required for prototyping.
The square 2×2 configuration keeps the holder compact. Using rechargeable NiMH batteries gives approximately 5.2 V fully charged to 4.4 V discharged, making it a convenient match for 5 V projects. With alkaline batteries (6.4 V fresh), a 1N4001 diode in series can drop the voltage to approximately 5.3 V.
Key Features
- Breadboard-Ready – Premium jumper header wires plug directly into breadboards
- Compact 2×2 Layout – Four AA batteries in a square configuration
- Series Connection – Nominal 6 V (alkaline) or 4.8 V (NiMH rechargeable)
- Solderable – Wires can also be soldered to a PCB
Voltage Output
- Alkaline – 6.4 V (fresh) to 4.0 V (depleted)
- NiMH Rechargeable – 5.2 V (fully charged) to 4.4 V (discharged)
Ideal For
- Breadboard prototyping with battery power
- 5 V Arduino and microcontroller projects (with NiMH batteries)
- Portable electronics projects
Package Contents
- 1× 2×2 AA battery holder with premium jumper header wires
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
