4AA battery holder with wire, wire end optional

Product Name: 4 AA (Size 5) Parallel 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. Unlike common long rectangular battery boxes, it features a parallel layout of four batteries. This design makes the holder approximately square in shape, greatly optimizing the use of flat space and making it suitable 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. The drawing indicates its flame retardant rating as UL94-HB, with an operating temperature range of -10°C to 80°C.
Contacts: Internally, there are high-elasticity nickel-plated spiral springs (specification: 0.65mm 65C spring steel wire) and metal tabs to ensure secure battery contact. The rivets are made of nickel-plated brass.

Functional Design (Key Features):
Coverless and Switchless: This model features an open skeleton design with no protective cover or integrated switch. The batteries are installed directly exposed, making it suitable for installation inside devices with external casing protection.
Wired Output: Red and black wires are directly led out from the side (red wire for positive, black wire for negative). The drawing specifies the wire as UL1007 26# AWG, with a temperature resistance of 80°C, a length of approximately 150±5mm, and the ends are stripped and tinned 5±1mm for easy direct welding or terminal connection.
Mounting Holes: The battery holder's partition and edges have round screw mounting holes (diameter φ3.5mm) for securing the holder firmly to the device's base plate or panel.

Dimension Specifications (Based on Drawing):
Total Length: 61.65mm (marked as 61,65)
Total Width: 57.2mm
Height: 15.5mm
This is a very compact square footprint, perfect for flat devices with strict length-to-width ratio requirements.

Electrical Characteristics: Internally, it's designed as a series circuit, and four AA batteries can provide a DC output voltage of 6V. Complies with RoHS environmental standards.
