BATTERY Contacts FOR 'AA' Button Battery 5224

Huizhou Antenk Electronics Co., Ltd. introduces the BATTERY Contacts FOR 'AA' Button Battery Model 5224, a specialized conductive component designed to interface between standard AA battery terminals and button/coin cell battery configurations. Unlike conventional battery contacts, Model 5224 features a unique hybrid design – one end accommodates the flat negative terminal or positive button of an AA battery, while the opposite end is engineered to contact button battery (e.g., CR2032, CR2025) surfaces. Manufactured from premium phosphor bronze (C5191) with nickel or selective gold plating, this contact delivers ultra-low electrical resistance below 25 milliohms and exceptional corrosion resistance. Key functional characteristics include a dual-profile stamped structure with a reinforced spring arm providing consistent normal force of 70–110 grams. The contact supports continuous currents up to 3A (AA side) and 200mA (button cell side), operating reliably from -25°C to +85°C. Its precision-engineered geometry includes anti-rotation tabs and polarized alignment features to prevent incorrect battery installation. The product is fully RoHS, REACH, and conflict mineral compliant.

 

The BATTERY Contacts Model 5224 (AA to Button Battery) is ideal for hybrid power applications where devices need to accept both AA and button battery formats, or where a button cell serves as backup memory power alongside an AA main battery. Typical applications include PC motherboards (AA backup for RTC/CMOS alongside CR2032), industrial control panels, programmable logic controllers (PLCs), smart meters, security alarm panels, medical monitors with redundant power, electronic toys with dual power options, and IoT gateway devices. The contact's unique design eliminates the need for separate battery holders for different cell types, reducing BOM costs and PCB space by up to 40%. Model 5224 accommodates standard AA battery dimensions (49.2mm–50.5mm length) and common button cell diameters (20mm for CR2032) simultaneously. Its independent spring contacts prevent "battery rocking" and maintain connection even when one battery type is not populated. Cycle life exceeds 6,000 insertions on the AA side and 3,000 on the button cell side. The contact also includes built-in polarity keying to prevent reverse insertion damage.

 

Huizhou Antenk Electronics Co., Ltd. leverages over 15 years of precision stamping and battery contact engineering expertise. Unlike many competitors who offer only single-battery-type contacts requiring separate components for hybrid applications, Antenk's Model 5224 is an integrated AA-to-button-cell solution that simplifies design and reduces assembly costs. While other suppliers typically impose high MOQs (10,000+ pieces) and charge substantial tooling fees for custom hybrid designs, Antenk offers low MOQs starting at only 1,000 units with flexible customization – including alternative materials (beryllium copper for high-reliability, stainless steel for cost optimization), plating finishes (gold for medical/industrial, selective gold for mixed circuits, matte tin for general use), contact force adjustments (light, standard, or heavy), and custom tail geometries (through-hole, SMT, or wire-lead). Unlike competitors who rely on batch sampling (AQL), Antenk performs 100% automated optical inspection (AOI) plus rigorous testing per EIA-364 standards: contact resistance, spring force validation, insertion cycle testing, and 48-hour salt spray corrosion testing. Antenk provides free engineering samples, complete 3D CAD models, and technical support within 24 hours.
