2 Cell AAA Battery Holder (Flat Type)

Description

The 2 Cell AA Battery Holder (Flat Type) is a staple component for powering small-scale DIY electronics, hobby robotics, and custom prototyping projects. Designed to hold two standard AA batteries, this holder connects the cells in series to output a combined nominal voltage of 3V DC (1.5V + 1.5V).

Available at Tomson Electronics, this "flat type" configuration ensures the batteries sit side-by-side. This creates a stable, low-profile footprint that easily mounts flat against the chassis of small robotic chassis or inside 3D-printed project boxes. It comes equipped with standard red (positive) and black (negative) pre-stripped wire leads, making it incredibly easy to solder directly to your custom PCBs, power switches, or motor terminals.

Applications

• Hobby Robotics: A great lightweight power source for small, 3V DC motors used in DIY motorized cars and bristlebots.
• LED Displays: Providing portable power to custom LED string lights, decorative lighting, or wearable tech.
• Microcontroller Projects: Powering ultra-low-power 3.3V microcontrollers (with an appropriate LDO regulator) or educational kits.
• Replacement Parts: Fixing corroded or broken battery compartments in standard household toys and electronics.

Frequently Asked Questions (FAQ)

Q: Are the batteries in this holder wired in series or parallel?
A: They are wired in series. This means the voltage of the two 1.5V AA batteries is added together, providing a total output of 3V. The current capacity (mAh) remains the same as a single AA battery.

Q: Does this holder feature a built-in ON/OFF switch or cover?
A: No, this is an open-face battery holder with direct wire leads. If you need to easily cut power to your circuit, you will need to solder a separate physical switch (like a slide or toggle switch) in line with the red wire.

Q: Can I use rechargeable AA batteries in this holder?
A: Yes! Standard NiMH rechargeable AA batteries fit perfectly. However, remember that rechargeable NiMH batteries have a lower nominal voltage of 1.2V per cell. Therefore, using two of them in this holder will output 2.4V instead of 3V.
