Product details
Huizhou Antenk Electronics Co., Ltd. presents the BATTERY Contacts FOR 'AA' Dual Spring Battery Model 5228, a premium conductive component featuring an innovative dual-spring design for AA battery negative terminals. Unlike traditional single-spring contacts, Model 5228 incorporates two independent coil springs or parallel leaf springs that work in tandem to provide redundant electrical paths and superior mechanical stability. Manufactured from high-grade phosphor bronze (C5191) with a nickel or selective tin plating, this dual-spring contact delivers ultra-low resistance below 20 milliohms per spring and exceptional corrosion resistance. Key functional characteristics include a balanced normal force of 60–80 grams per spring (120–160 grams total), ensuring consistent battery connection even under extreme vibration, thermal cycling, or battery swelling. The dual-spring architecture also compensates for misalignment during battery insertion, reducing assembly rejects. Model 5228 supports continuous currents up to 3A and operates reliably from -30°C to +85°C. Its precision-stamped geometry is compatible with most standard AA battery holders, while the dual solder tails (one per spring) provide redundant PCB attachment for enhanced reliability. The product is fully RoHS, REACH, and conflict mineral compliant.
The BATTERY Contacts Model 5228 (AA Dual Spring) is ideal for demanding applications where single-point battery contact failure is unacceptable. Typical use cases include industrial handheld devices, medical monitoring equipment (glucometers, portable patient monitors), military-grade flashlights, automotive key fobs, vibration-prone machinery controls, IoT sensors, and backup power modules. In consumer electronics, it excels in high-end remote controls, wireless gaming peripherals, and portable audio devices where intermittent power due to shock or movement cannot be tolerated. The dual-spring design provides inherent redundancy: even if one spring loses tension or becomes contaminated, the second spring maintains electrical continuity, dramatically reducing field failure rates. Compared to conventional single-spring or solid stamped contacts, Model 5228 offers superior shock absorption (tested to withstand 10G vibration), longer cycle life exceeding 10,000 insertion/removal cycles, and consistent contact resistance across temperature extremes. The dual contact points also minimize contact arcing under load, extending battery and device life.
Huizhou Antenk Electronics Co., Ltd. brings over 15 years of precision stamping expertise to the battery contact industry. Unlike many competitors who offer only basic single-spring contacts with limited quality control, Antenk's Model 5228 dual-spring design is engineered for mission-critical reliability. While other suppliers typically require high MOQs (10,000+ pieces) and offer no customization, Antenk provides low MOQs starting at 1,000 units with full customization options – including alternative materials (beryllium copper for extreme durability, stainless steel for cost optimization), plating finishes (gold for medical/high-reliability, matte tin for general use), spring tension adjustments (light, standard, or heavy), and custom tail geometries for non-standard PCB layouts. Unlike competitors who rely on batch sampling, Antenk performs 100% in-process inspection using automated vision systems, plus rigorous testing per EIA-364 standards: contact resistance, spring force validation, and 48-hour salt spray corrosion testing (exceeding the industry standard of 24 hours). Antenk also provides free engineering samples, complete 3D CAD models, and dedicated technical support within 24 hours. For global buyers seeking a robust, redundant, and customizable AA dual-spring battery contact that outperforms single-spring alternatives, Model 5228 from Antenk is the definitive choice.
