3AAA rechargeable round battery pack with lid and switch

Product Name: 3 AAA Embedded Round Battery Holder (with Lid and Switch)

Appearance and Structural Features:
Overall Design: This is a uniquely designed white round battery holder, specifically designed to hold two AAA batteries. Unlike traditional rectangular battery holders, it features a circular base layout, which is perfectly suited for installation on cylindrical devices, round lights, or products that require a streamlined appearance.

Material and Manufacturing: The outer shell is made of high-quality white engineering plastic (usually ABS), with a smooth and clean surface that offers good insulation and aesthetics.

Functional Design (Key Features):
Flip-Top Design: The top of the battery compartment is equipped with a flip-top lid that snaps on with a clip, and the edge of the lid has a convenient groove for easy opening. When closed, it effectively secures the batteries to prevent them from falling out due to vibration and also serves as a dust shield.

Integrated Toggle Switch: A miniature toggle switch is integrated into the edge of the circular base, allowing users to directly control the power on/off without having to open the lid.

Mounting Holes: Three round screw mounting holes are evenly spaced around the edge of the circular base (in a triangular pattern), making it ideal for securely fixing the battery holder to flat or cylindrical surfaces.

Contact System:
Negative Terminal: An internally mounted high-elasticity nickel-plated coil spring ensures tight battery contact.
Positive Terminal: The other end is equipped with a metal spring contact.

Connection Method: The bottom has metal spring tabs suitable for soldering wires or direct insertion into circuit board sockets.

Dimension Specifications:
Diameter: 69.5mm
Height: 14mm
Weight: Approximately 20g

Electrical Characteristics: The internal circuit is designed as a series connection, and two AAA batteries can provide a DC output voltage of 4.5V.
