Huizhou Antenk Electronics Co., Ltd., an IATF16949:2016, ISO9001 and ISO14001 certified manufacturer founded in 2004 with over 250 employees and a 10,000m² facility, proudly presents the Battery Holder 54 STYLE FOR 16-19MM BATTERY. This innovative 54‑series battery holder is specifically engineered to accommodate cylindrical batteries with diameters ranging from 16mm to 19mm (e.g., CR123A, CR2, 18350, 16340, 14500 with sleeve). Unlike fixed‑size holders, the 54 STYLE features a sliding positive contact plate that allows tool‑free adjustment to securely hold different cell diameters, eliminating the need for multiple holder SKUs. Manufactured using our 8 Japanese/Taiwanese 35‑120 ton precision injection molding machines with UL94V‑0 rated PBT or nylon 6/6, the holder body provides excellent mechanical strength and flame resistance. The integrated negative terminal is a gold‑plated or nickel‑plated phosphor bronze coil spring, while the adjustable positive contact uses a dual‑leaf stamped design. Key characteristics include a contact resistance below 25 milliohms, retention force of 120–180g, support for continuous currents up to 4A, operating temperature range -30°C to +85°C, and through‑hole or wire‑lead termination options. The product is RoHS, REACH compliant and UL recognized (E472792).
Application Scope: The 54 STYLE holder is ideal for devices where battery type may vary or where design flexibility is required, including portable medical devices (insulin pumps, pulse oximeters), high‑power flashlights, IoT sensors with interchangeable batteries, industrial handheld terminals, remote control systems, backup power modules, and DIY electronics projects – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the PCB‑mount tabs or pre‑attached wire leads to the circuit. Slide the positive contact to match the exact battery length (battery diameter determines holder grip; all 16‑19mm cells fit the same body). Insert the battery negative end first into the coil spring, then press the positive end against the adjustable contact – the sliding mechanism will self‑lock. To remove, slide the positive contact back or pry the battery using a plastic tool. Precautions: Do not exceed 4A continuous current; ensure the sliding contact is fully locked before use; avoid using batteries longer than 70mm; operate within -30°C to +85°C range. Advantages Over Competitors: Unlike competitors who sell separate holders for CR123A (17mm), CR2 (15.6mm), and 18350 (18mm) – forcing customers to stock multiple parts – Antenk’s 54 STYLE covers all with one adjustable design, reducing inventory costs by up to 70%. Competitors often use cheap ABS that warps under high current heat; Antenk uses PBT with 130°C heat deflection temperature. While others require 10,000+ MOQ for each fixed size, Antenk offers low MOQs (1,000 units) for the universal 54 STYLE with no tooling fees. Our IATF16949 certification ensures automotive‑grade quality. Additionally, our 48‑hour salt spray testing and 10,000‑cycle adjustment validation guarantee long‑term reliability.
Antenk’s vertical integration delivers consistent quality for the 54 STYLE adjustable battery holder. Process flow: (1) In‑house mold design and fabrication using our 250+ plastic injection molds (dedicated 54‑series mold with sliding channel); (2) Precision injection molding on 8 Japanese/Taiwanese machines using PBT or nylon 6/6 – the sliding mechanism requires tight tolerance control of ±0.03mm on guide rails; (3) High‑speed stamping of positive and negative terminals on 11 Japanese/Taiwanese presses using 0.20mm–0.30mm phosphor bronze strip; (4) Terminal plating: nickel (2μm) or selective gold (0.4μm) for medical/industrial versions; (5) Automated spring coiling for negative contact (Japanese CNC coilers); (6) Assembly: insert terminals into molded base, assemble sliding positive contact with pre‑plated leaf spring, attach wire leads (if specified); (7) 100% sliding force and contact alignment verification; (8) Contact resistance and retention force testing per EIA-364-06/13; (9) 48‑hour salt spray corrosion testing; (10) Final QC with lot traceability and dimensional report including sliding travel range. Our laboratory houses 20+ testing devices including profile projectors, environmental chambers, and insertion force testers. With 250+ employees, 18+ mold‑making machines, and 180+ automatic assembly machines, we provide free samples, complete 2D/3D CAD drawings showing adjustment range, and 24‑hour technical support. Contact Antenk today for a quotation – we typically respond within 4 hours and ship 54 STYLE holder samples within 3 days. Ask about our volume discounts (5,000+ units) and custom options (different wire lengths, gold plating for medical devices, or custom sliding range for other battery diameters). With 70% of our products exported worldwide and 18 years of experience, Antenk is your trusted partner for flexible, multi‑diameter battery holder solutions.
