Product details

Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001:2015 and ISO14001:2015 certified high-tech enterprise founded in 2004 with over 300 employees and a 10000 square meter Huizhou facility, presents the Battery Contacts 127 (Model BS-M-SI-R-127). This precision-engineered battery contact is specifically designed for the negative terminal interface of AA-size cylindrical batteries, featuring a stamped dimple spring geometry that delivers consistent compression force. Manufactured on our 9 Japanese/Taiwanese high-speed precision presses from high-conductivity copper alloy, stainless steel, or iron with optional CT, silver, or nickel plating, the contact achieves ultra-low resistance below 15 milliohms at full compression. Key characteristics include a consistent normal force of 80–130 grams across 5,000+ insertion cycles, support for continuous currents up to 3A (peak 5A), and an operating temperature range from -40°C to +105°C. The multi-point contact design features a coined nose that distributes force evenly across the battery terminal, ensuring gas-tight connections that resist oxidation and environmental degradation across the device lifetime. The product is RoHS and REACH compliant and UL recognized under E472792.

This AA battery negative contact is widely deployed across consumer electronics, portable medical devices, industrial instrumentation, and IoT products requiring dependable primary battery power, including glucose meters, wireless sensors, remote controls, children‘s electronic toys, digital thermometers, and real-time backup modules – markets where Antenk already serves customers including Flextronics, Foxconn, and Fortune 500 companies across the USA, Germany, South Korea, India, Russia, and beyond. Usage method: Solder the contact’s lead frame, solder tail, or wire termination (crimp or solder) to the PCB using standard reflow, wave, or hand soldering. For optimal performance, pair the BS-M-SI-R-127 with a mating positive contact, ensuring proper battery orientation before final assembly. The contact may also be integrated into custom battery holders or battery compartments with or without wire leads per application requirements. Precautions: Do not exceed 3A continuous current; avoid reverse polarity installation; operate within -40°C to +105°C range. Advantages Over Competitors: Unlike competitors who use single-point stamped tabs prone to force relaxation and contact resistance drift over thermal cycles, Antenk’s BS-M-SI-R-127 incorporates a coined-nose multi-point contact terminal with rounded contact edges for low insertion force (LIF) and a large contact surface area for a reliable connection and excellent low-level contact resistance (LLCR). Competitors often use generic brass or tin-plated steel that corrodes under humidity; Antenk uses selective nickel plating with optional gold or silver on critical contact areas for oxidation resistance and consistent performance. While others require 10,000+ MOQ for stamped contact tooling with limited customization, Antenk offers low MOQs (1,000 units) with no tooling fees for standard configurations (spring force, plating, termination style, and orientation). Our IATF16949 certification ensures automotive-grade quality management, and our in-house 40+ lab test devices (including XRF, environmental chambers, and 3D profilers) guarantee every batch meets EIA-364 standards for contact resistance, spring force, and salt spray corrosion.

Antenk‘s vertical integration delivers consistent quality for the Battery Contacts 127. Process flow: First, in-house mold design and fabrication using our 180+ precision terminal molds (progressive die with coined nose feature). Second, high-speed stamping on 9 Japanese/Taiwanese presses (11 machines total) using 0.20mm to 0.30mm phosphor bronze or beryllium copper strip – the coined nose geometry requires precise die clearance of ±0.01mm. Third, selective barrel plating: nickel underplate (2–3μm) plus optional CT, silver, or gold on contact tips (0.4–0.8μm), with pure tin on solder tails for excellent solderability. Fourth, 100 percent AOI dimensional inspection with critical tolerance of ±0.03mm on contact height, dimple position, and coined nose radius – a tighter standard than the industry typical ±0.10mm. Fifth, spring force testing per EIA-364-04 (80–130 grams at full compression, validated on 100% of production). Sixth, contact resistance testing per EIA-364-06 (<15 milliohms across 5,000 simulated insertions). Seventh, thermal cycling and 48-hour salt spray corrosion testing (sample-based) to validate environmental resistance. Eighth, automated lead frame and solder tail formation, followed by 100 percent coplanarity verification (solder pads within 0.08mm). Ninth, final QC with lot traceability and dimensional reports including spring force distribution histogram. Our laboratory houses more than 40 testing devices including XRF for plating thickness verification, profile projectors, environmental chambers, and automated spring testers. With over 300 employees, more than 18 mold-making machines, and over 180 automatic assembly machines, we provide free samples, complete 2D/3D CAD drawings, and 24-hour technical support.
