Product details
Huizhou Antenk Electronics Co., Ltd., an ISO9001, ISO14001 and IATF16949:2016 certified manufacturer founded in 2004 with over 250 employees and a 10,000m² facility in Shenzhen and Dongguan, proudly presents the BATTERY Contacts FOR 'AA' Female Battery Model 5220. This precision-engineered component is specifically designed for the negative terminal (female side) of standard AA batteries, featuring a coil spring or dual-leaf elastic structure that provides a consistent normal force of 70–110 grams. Manufactured in our Dongguan production base using 11 sets of Japanese/Taiwanese high-speed precision stamping presses and premium phosphor bronze (C5191) or beryllium copper, Model 5220 delivers ultra-low contact resistance below 20 milliohms with nickel, selective tin, or gold plating options. Key characteristics include support for continuous currents up to 3A, reliable operation from -30°C to +85°C, and an integrated anti-overstress stop to prevent permanent deformation during battery insertion. The product is RoHS, REACH compliant and UL recognized (E472792), with 100% automated optical inspection (AOI) performed on every batch using our 180+ automatic assembly machines and 180+ precision terminal molds.
Application Scope: Model 5220 is widely used in remote controls, wireless keyboards/mice, portable flashlights, digital bathroom scales, blood pressure monitors, children's toys, security sensors, automotive key fobs, and industrial instruments – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the contact's tail via through-hole or SMT to the PCB, ensuring the spring/receiving surface faces outward. Insert the AA battery negative terminal (flat end) against this contact, with the positive end against a male battery contact. Precautions: Do not exceed 3A continuous current; avoid reverse polarity installation; operate within -30°C to +85°C range; ensure proper alignment during battery insertion to prevent spring damage. Advantages Over Competitors: Unlike generic contacts with loose tolerances (±0.15mm) and inconsistent spring forces, Antenk’s Model 5220 maintains ±0.05mm precision using Japanese/Taiwanese tooling. Competitors often require 10,000+ MOQ and

500–1,000 tooling fees; Antenk offers low MOQs (1,000 units) with no tooling fees for standard modifications (materials, plating, spring tension, tail geometry). Our IATF16949 certification ensures automotive-grade quality management – most battery contact suppliers lack this. Additionally, our 48-hour salt spray testing (double industry standard of 24 hours) and 10,000-cycle validation ensure superior reliability.
Antenk’s vertical integration delivers consistent quality for Model 5220. Process flow: (1) In-house mold design and fabrication (180+ precision terminal molds); (2) High-speed stamping on Japanese/Taiwanese presses (11 machines) at up to 800 strokes/minute; (3) Barrel plating (nickel/tin/gold) with real-time thickness monitoring; (4) 100% AOI dimensional inspection (±0.05mm tolerance); (5) Spring force testing per EIA-364-04; (6) Contact resistance testing per EIA-364-06; (7) 48-hour salt spray corrosion testing; (8) Automated assembly on 180+ machines; (9) Final QC with lot traceability. Our laboratory houses 20+ testing devices including profile projectors, hardness testers, and environmental chambers. With 250+ employees including dedicated engineering and QA teams, and 18+ mold-making machines, we provide free samples, complete 2D/3D CAD drawings, and 24-hour technical support.
