Product Name: 2 AA (Size 5) Long Battery Holder with Wires/Series
Connection
Appearance and Structural Features:
Overall Structure: This is a distinctive, slender black battery
holder designed specifically for two AA (Size 5) batteries. Its
most notable feature is its "long rectangular" layout, with the two
battery compartments arranged in a straight line (in series) rather
than side by side. This design significantly reduces the width,
making it perfect for installation in tight spaces.
Material and Manufacturing: The casing is made of high-quality
black engineering plastic (usually ABS), with a smooth surface that
offers good insulation and mechanical strength. The bottom is
clearly marked with "2xAA" to indicate its specifications.
Contact System:
Negative Terminal: One end inside features a highly elastic
nickel-plated spiral spring that can effectively accommodate slight
variations in battery size, ensuring secure installation and low
contact resistance.
Positive Terminal: The other end has metal prongs or spring
contacts (brass-colored contacts visible in the image).
Internal Connection: The two battery compartments are connected in
series using internal metal strips or wires, ensuring a total
output voltage of 3V.
Connection Method: Red and black wires are directly led out from
the back (red wire for positive, black wire for negative). This
wired design eliminates the need for soldering pins and allows for
direct connection to circuit boards or other electronic components,
making it ideal for DIY projects, repairs, replacements, or
situations where soldering is inconvenient.
Dimension Specifications:
