BATTERY Contacts FOR 'AA'Dual Battery 5227

Huizhou Antenk Electronics Co., Ltd. introduces the BATTERY Contacts FOR 'AA' Dual Battery Model 5227, a precision-engineered contact solution designed to accommodate two AA batteries in series or parallel configurations within a single compact assembly. Unlike individual battery contacts that require separate mounting, Model 5227 integrates two negative (female) contact positions or one positive and one negative contact on a unified stamped carrier, reducing assembly time and component count. Manufactured from high-performance phosphor bronze (C5191) with a nickel or matte tin plating, this dual-battery contact delivers ultra-low resistance below 25 milliohms per channel and excellent corrosion resistance. Key functional features include independent spring-loaded contact points for each battery cell, providing a consistent normal force of 80–120 grams per battery, which accommodates slight variations in battery length and compensates for cell swelling during discharge. The contact supports continuous currents up to 5A (combined) and operates reliably from -25°C to +85°C. Its dual-tail or quad-tail solder lug design ensures secure PCB attachment, while the integrated plastic alignment ribs prevent reverse polarity insertion. The product is fully RoHS, REACH, and conflict mineral compliant.

 

The BATTERY Contacts Model 5227 (AA Dual Battery) is ideal for devices requiring two AA batteries to double voltage (series) or extend runtime (parallel). Typical applications include portable medical devices (blood pressure monitors, digital thermometers), consumer electronics (wireless keyboards, computer mice, TV remote controls), children's electronic toys, handheld flashlights, digital cameras, portable radios, and IoT sensors. In industrial settings, it serves data loggers, portable testing equipment, and backup memory power modules. The dual-battery integrated design offers significant advantages over using two separate single-battery contacts: it eliminates misalignment during assembly, reduces solder joints by 50%, lowers overall component height, and ensures consistent spacing between batteries for optimal heat dissipation. Model 5227's independent spring contacts prevent "battery rocking" – a common failure mode where one battery loses connection while the other remains engaged. Additionally, the contact geometry is optimized for both alkaline and rechargeable NiMH AA batteries, accommodating length variations from 49.2mm to 50.5mm without compromising electrical stability. Cycle life exceeds 7,000 insertion/removal cycles per contact point.

 

Huizhou Antenk Electronics Co., Ltd. brings over 15 years of precision stamping and connector manufacturing expertise to the battery contact market. Unlike many competitors who offer only generic, single-battery contacts that require manual assembly alignment, Antenk's Model 5227 is an integrated dual-battery solution engineered for automated PCB assembly. While other suppliers typically impose high MOQs (10,000+ pieces) and charge premium prices for custom configurations, Antenk offers low MOQs starting at 1,000 units with flexible customization options – including alternative materials (beryllium copper for extreme durability, stainless steel for cost-sensitive projects), plating finishes (gold for medical/high-reliability applications, enhanced nickel for humid environments), and custom spring tensions (light, standard, or heavy). Unlike competitors who rely on batch sampling, Antenk performs 100% automated optical inspection (AOI) on every stamped contact, plus rigorous testing per EIA-364 standards: contact resistance, insertion/withdrawal force, spring fatigue (10,000 cycles), and 48-hour salt spray corrosion testing. Antenk also provides free engineering samples, complete 2D/3D technical drawings, and responsive technical support within 24 hours. For global buyers seeking a cost-effective, reliable, and easy-to-assemble dual AA battery contact solution, Model 5227 from Antenk delivers superior performance and value.
