3AA battery holder with 15cm wire, open type

Product Name: 3 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 three AA (Size 5) batteries. Unlike common long rectangular battery boxes, it features a parallel layout of three batteries. This design makes the holder approximately square in shape, greatly optimizing the use of flat space and making it 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. 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 built-in switch. The batteries are installed directly exposed, making it suitable for use inside devices with an external casing.
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. The length is approximately 150±5mm, with the ends stripped and tinned for 5±1mm, making it easy to solder directly or connect to terminals.
Mounting Holes: The battery holder's partitions and edges have round screw mounting holes (diameter φ5mm) for securing the holder firmly to the device's base plate or panel.

Dimension Specifications (Based on Drawings):
Total Length: 57.8mm
Total Width: 46.5mm
Height: 15mm
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 the three AA batteries can provide a DC output voltage of 4.5V. Complies with RoHS environmental standards.
