The JT-BC-CR123A-625-THM CR123A Negative Battery Contact is engineered to provide consistent mechanical retention and reliable electrical connection for CR123A-powered devices. We designed this stamped negative-terminal contact to interface directly with the negative electrode of the CR123A cell, with a verified footprint envelope of 13.50±0.15 mm by 14.60±0.30 mm. Its geometry supports stable battery interface performance across compact electronic, commercial, and industrial product designs.

Manufacturing & Quality
We fabricate this contact from 0.30 mm spring steel strip stock to deliver repeatable deflection, controlled spring return force, and long-cycle durability. A nickel plate finish is applied to help resist oxidation, reduce surface wear, and sustain low contact resistance over service life. Our test data shows dimensional repeatability within ±0.20 mm on critical width and length axes, while the 37.05±0.20 mm developed length helps maintain precise spring arm compliance geometry.
Engineering Protocol
The spring arm profile is engineered to a free height of 2.48±0.30 mm above the base plane to support controlled preload and secure battery retention. We maintain a 2.20±0.20 mm tab width, with secondary dimensions of 13.10±0.25 mm and 12.80±0.20 mm to align with common CR123A holder and compartment layouts. Contact tip geometry references a published pitch dimension of 802.00±0.20 mm for tooling and fit validation within holder-dependent through-hole or press-fit assemblies.
To ensure 1:1 precision replacement, deployment of our Senior NPI Engineering Team is required. Please review the [Technical Datasheets] and [2D Footprint Specs]. Request Engineering Support. We will provide matching PDF drawings within our strict 12-hour fast response SLA.
Customization Options
For OEM and industrial programs, we support customization of tab geometry, plating specification, strip carrier orientation, reel pitch, and packaging format. Custom battery contact solutions may also be developed for target retention force, footprint, and form-factor requirements. Contact our NPI team with assembly drawings for design-specific evaluation and precision replacement support.
