The EH-AAX8B/DC Battery Holder is a high-capacity power solution engineered for projects requiring a stable 12V DC supply. This unit combines an 8-slot AA battery array with an integrated On/Off switch and a standard DC barrel plug, providing a complete, portable power management system for professional and hobbyist electronics.
Universal 2.1mm DC Connector: Equipped with a pre-wired 2.1mm x 5.5mm DC male barrel jack, ensuring seamless compatibility with 12V-rated Arduino boards, monitors, and security equipment.
Dedicated Power Toggle: Features a built-in ON/OFF slide switch located on the side of the housing, allowing for easy energy management without disconnecting the cable.
12V Series Configuration: Optimized to hold eight AA batteries in a series circuit, delivering a powerful 12.0V output (alkaline) or 9.6V (rechargeable NiMH).
Secure Slide-Lock Cover: The fully enclosed ABS housing includes a removable cover that snaps firmly into place, protecting the internal cells and contacts from accidental shorts or debris.
Industrial-Grade Contacts: Utilizes nickel-plated steel coil springs to ensure low-resistance connectivity and long-term durability in high-vibration applications.
Model Number: EH-AAX8B/DC.
Battery Capacity: 8x AA
Output Connector: 2.1mm x 5.5mm DC Male Plug (Center Positive).
Housing Material: Heavy-duty Black ABS Plastic.
Portable 12V Electronics: Powers field monitors, 12V LED strips, and small audio amplifiers where wall power is inaccessible.
Advanced Robotics: Ideal for driving high-torque 12V motors and controlling large robotic platforms.
Security & Surveillance: Serves as a versatile power pack for testing 12V CCTV cameras and remote sensor arrays.
Emergency Backup: Provides a reliable secondary power source for telecommunications equipment and home automation hubs.
Is the DC plug center-positive? Yes, the integrated DC jack is wired for the industry-standard Center Positive polarity, making it safe for the vast majority of consumer and industrial electronics.
Can I use this for devices that need more than 12V? This holder is designed for a max nominal output of 12V using standard AA batteries. For devices requiring higher voltage, multiple units would need to be wired together, though caution is advised.
Does the switch cut power to the DC plug? Absolutely. The integrated switch breaks the circuit between the battery array and the DC output, allowing you to safely leave the batteries inside the unit while it is turned off.
