Battery Holder 57 STYLE FOR AA BATTERY

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 in Shenzhen and Dongguan, proudly presents the Battery Holder 57 STYLE FOR AA BATTERY. This 57‑series single‑cell battery holder is a compact, injection‑molded enclosure designed to securely house one standard AA (LR6) battery while providing integrated positive and negative terminals for easy PCB or wire connection. Manufactured using our 8 Japanese/Taiwanese 35‑120 ton precision injection molding machines with high‑durability PBT or nylon 6/6 (UL94V‑0 flame rating), the holder features a low‑profile design with a total height of just 8.5mm. The integrated nickel‑plated phosphor bronze spring contacts (positive nub and negative coil) deliver a contact resistance below 30 milliohms and a consistent retention force of 150–200g. Key characteristics include a polarized snap‑fit cover option (closed version), through‑hole or SMT solder tabs, operating temperature range from -25°C to +85°C, and support for continuous currents up to 3A. The product is RoHS, REACH compliant and UL recognized (E472792), with 100% automated inspection.

 

Application Scope: The 57 STYLE AA battery holder is ideal for portable electronics, DIY projects, memory backup modules, IoT sensors, remote controls, children’s toys, digital thermometers, portable flashlights, and prototype breadboards – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the two solder tabs (positive + negative) to a PCB using wave or hand soldering. Alternatively, use the pre‑attached 150mm wire leads (optional) for off‑board mounting. Insert the AA battery with correct polarity as marked on the holder – the positive end contacts the raised nub, the negative end engages the coil spring. The snap‑fit cover (if specified) locks with an audible click. Precautions: Do not exceed 3A continuous current; avoid reverse battery insertion; do not immerse in liquids; operate within -25°C to +85°C range. Advantages Over Competitors: Unlike competitors who use low‑grade ABS that becomes brittle over time, Antenk’s 57 STYLE holder uses UL94V‑0 rated PBT or nylon for superior heat and impact resistance. Competitors often have weak negative springs that lose tension after 500 cycles; Antenk uses a reinforced dual‑coil spring rated for 8,000 insertion cycles. While other manufacturers require 10,000+ MOQ for a custom color or lead length, Antenk offers low MOQs (1,000 units) with no tooling fees for standard modifications (wire length, color, or terminal plating). Our IATF16949 certification ensures automotive‑grade quality control. Additionally, our 48‑hour salt spray testing and 10,000‑cycle mechanical endurance tests guarantee long‑term reliability.

 

Antenk’s vertical integration delivers consistent quality for the 57 STYLE AA battery holder. Process flow: (1) In‑house mold design and fabrication using our 250+ plastic injection molds; (2) Precision injection molding on 8 Japanese/Taiwanese machines using PBT or nylon 6/6 resin – all molds run with hot runner systems for consistent fill; (3) High‑speed stamping of positive and negative terminals on 11 Japanese/Taiwanese presses using 0.25mm phosphor bronze strip; (4) Terminal plating: nickel (2μm) or selective tin; (5) Automated spring coiling for negative contact (using Japanese CNC coilers); (6) Semi‑automatic assembly: terminal insertion into holder body, spring attachment, and wire soldering (if applicable); (7) 100% electrical continuity and polarity verification; (8) Insertion/withdrawal force testing per EIA-364-13; (9) 48‑hour salt spray corrosion testing (sample‑based); (10) Final QC with lot traceability and dimensional report. Our laboratory houses 20+ testing devices including profile projectors, hardness testers, environmental chambers, and insertion force testers. With 250+ employees including dedicated engineering and QA teams, 18+ mold‑making machines, and 180+ automatic assembly machines, we provide free samples, complete 2D/3D CAD drawings, and 24‑hour technical support.
