1*D battery holder with high-quality black plastic battery storage compartment

Product Name: 1-cell D-Type Battery Holder (with Wires)

Appearance and Structural Features:
Overall Structure: This is a black, single-cell battery holder designed specifically for accommodating one D-type (AA/MA) battery. It features an open-frame design without a fully enclosed shell, which greatly reduces its size and weight, making it perfect for applications with limited space.

Materials and Manufacturing Process:
Shell: The main body is made of black engineering plastic (usually ABS or PP), with a smooth surface and good insulation properties.
Contacts: One end inside has a highly elastic nickel-plated helical spring (for connecting to the negative terminal of the battery), and the other end has metal leaf or rivet contacts (for connecting to the positive terminal).

Functional Design (Key Features):
Wired Output: Red and black wires are directly led out from the tail (red wire for positive, black wire for negative). This pre-wired design eliminates the need for soldering, making it ideal for quick circuit connections.
Mounting Holes: Circular screw mounting holes are provided on the bottom and sides of the battery holder, allowing for easy and secure fixation to a device's base plate or panel.
No Cover or Switch: This model features a minimalist design with no protective cover or integrated switch. The battery is installed exposed, suitable for use inside devices with an outer shell.
