4-pack AA series ABS battery holders with 150mm leads, RoHs+CE certified

Product Name: 4-cell AA Battery Holder (with Wires/Screw Fixation)

Appearance and Structural Features:
Overall Structure: This is a black, double-sided battery holder with four slots, specifically designed for connecting 4 AA batteries in series. The inside clearly displays "2AA", "1.5V", and positive/negative polarity markings, with a total output voltage of 6V.
Material and Manufacturing: The casing is made of high-quality ABS engineering plastic with a matte finish, providing a good grip and being insulating and flame-retardant. The product meets RoHS + CE certification standards, ensuring it's environmentally friendly and safe.
Contact System:
Negative Terminal: High-elasticity nickel-plated coil springs are used, effectively accommodating slight variations in battery size for reliable and long-lasting contact.
Positive Terminal: Raised metal contacts (resembling rivets from certain angles) ensure low contact resistance.
Connection Method: Red and black wires are led out from the back (red for positive, black for negative), each about 150mm long. The ends are stripped and tinned for easy direct soldering or terminal connection.
Mounting Design: One end of the battery holder features protruding mounting lugs with 4 metal screw holes arranged in a rectangular pattern. This design allows users to securely fasten the holder to equipment enclosures or panels with screws, preventing it from falling off.
Dimensions:
Length: 57mm
Width: 31mm
Height: 29.5mm

Key Features:
Stable Installation: The unique four-hole screw fixation is more stable than ordinary clip-on or single-hole types, ideal for industrial or fixed equipment applications.
Safety Certification: Complies with RoHS and CE certifications, meeting environmental and safety requirements for export and high-standard electronic products.
Series Power Supply: Internally wired for series connection, providing a direct 6V output, simplifying circuit design.
