AA 3-Battery Case with cover

Triple AA Cell 4.5V Series Output: Holds three standard AA (1.5V) batteries in series to deliver a stable 4.5V DC power rail for microcontrollers, LED circuits, small motors, and IoT sensors.

Fully Enclosed Protective Cover: Features a removable slide-on cover that completely encloses the batteries, shielding them against dust, physical displacement, and accidental short circuits against nearby chassis components.

Pre-Stripped Color-Coded Lead Wires: Pre-wired with flexible red (positive) and black (negative) insulated copper lead wires for immediate soldering to circuit board pads or direct attachment to terminal connectors.

High-Tension Coil Spring Contacts: Nickel-plated steel spring terminals ensure firm, low-resistance contact pressure against AA cell terminals, preventing power dropouts during movement or structural vibration.

Molded Polarity Identification: Clear positive (+) and negative (-) polarity icons molded directly onto the base tray floor safeguard against reverse battery placement errors.

Durable ABS Construction: Molded from lightweight, impact-resistant black ABS plastic designed to withstand physical wear while keeping total project weight low.

Housing Material: High-impact, flame-retardant ABS composite plastic.

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