4 AA battery holders with wires The wire end is optional

Product Name: 4 AA (Size 5) Battery Holder with Wires, Skeleton Type

Appearance and Structural Features:
Overall Structure: This is a compact black battery holder designed specifically to accommodate four AA (Size 5) batteries. It features a layout with the batteries arranged side by side, giving it an almost square shape and greatly optimizing the use of flat space. Ideal for installation in flat or space-constrained devices.

Materials and Manufacturing:
Shell: The main body is made of black PP (polypropylene) resin, which offers good insulation and chemical resistance.
Contacts: Internally, there are high-elasticity nickel-plated coil springs (negative) and metal tabs (positive) to ensure secure battery contact. The rivets are made of nickel-plated brass for excellent conductivity.

Functional Design (Key Features):
Coverless and Switchless: This model features an open skeleton design with no protective cover or built-in switch. The batteries are installed directly exposed, making it suitable for use inside devices with protective enclosures.
Wired Output: Red and black wires are directly led out from the side (red for positive, black for negative). The wire ends are stripped and tinned for easy direct soldering or terminal connection.
Mounting Holes: The battery holder's partition and edges have round screw mounting holes, allowing for secure fixation of the holder to a device's base plate or panel.
