Product Name: 2 AA (Size 5) Back-to-Back Battery Holder (with Wires/Dual-Sided)
Appearance and Structural Features:
Overall Structure: This is a unique dual-sided battery holder designed to accommodate two AA (Size 5) batteries. Its most notable feature is the "back-to-back" design, where the two battery compartments are placed back to back with a partition in between. This design saves a lot of space and makes the holder more compact.
Materials and Manufacturing: The housing is made of black engineering plastic (usually ABS), which offers good insulation and durability. The surface is smooth with rounded edges.
Contact System:
Negative Terminal: High-elasticity nickel-plated coil springs are installed at both ends inside to ensure secure battery installation and good contact.
Positive Terminal: A metal tab or spring contact is located at the other end (brass-colored contacts visible in the image).
Connection Method: Red and black wires are led out from the back (red wire for positive, black wire for negative). This wired design makes it easy to connect directly to a circuit board or other electronic components without the need for soldering pins.
Dimension Specifications:
Length: 60mm
Width: 33mm
Height: 14mm
Electrical Characteristics: Due to the back-to-back series connection, this battery holder provides an output voltage of 3V (1.5V x 2).
