BATTERY Contacts FOR 'AA' Male Battery 5223
2 month ago
Product details
Huizhou Antenk Electronics Co., Ltd. presents the BATTERY Contacts FOR 'AA' Male Battery Model 5223, a precision-engineered conductive component specifically designed for the positive terminal (male side) of standard AA batteries. Model 5223 features an optimized raised button or convex dimple geometry with an integrated spring arm, ensuring reliable, low-resistance electrical connection while preventing accidental short circuits with adjacent cells or device housings. Manufactured from high-grade phosphor bronze (C5191) with nickel or selective tin plating, this contact delivers ultra-low electrical resistance below 15 milliohms – one of the lowest in its class – and exceptional corrosion resistance. Key functional characteristics include a precision-stamped raised dome structure with a reinforced fulcrum that provides a consistent normal force of 80–120 grams, ensuring stable electrical continuity even under extreme vibration, thermal cycling from -30°C to +85°C, or battery swelling during deep discharge. The contact supports continuous currents up to 3A (exceeding standard AA requirements) and features an optimized solder tail design supporting through-hole, SMT, or wire-lead termination. Its anti-overstress stop prevents permanent deformation during battery insertion. The product is fully RoHS, REACH, and conflict mineral compliant.
The BATTERY Contacts Model 5223 (AA Male) is widely deployed across consumer electronics, medical devices, industrial equipment, portable lighting, and automotive applications that demand reliable positive terminal connections. Typical applications include remote controls, wireless keyboards and mice, portable flashlights, digital cameras, children's electronic toys, blood glucose meters, portable radios, wall clocks, security sensors, and automotive key fobs. The male contact's precisely controlled dome height (typically 1.5mm–2.0mm) ensures perfect alignment with the AA cell's positive button terminal, eliminating off-center connections that cause arcing, intermittent power, or localized heating – a common failure point in competitor products. Unlike flat or recessed contacts, Model 5223's raised geometry with a micro-textured contact surface ensures positive mechanical engagement even after 10,000+ battery replacement cycles. The contact also accommodates manufacturing tolerances in AA battery length (49.2mm to 50.5mm) without losing spring tension. Its anti-vibration and shock-resistant design (tested to 12G) makes it ideal for handheld and portable devices. Cycle life exceeds 10,000 insertion/removal cycles with less than 5% increase in contact resistance.
Huizhou Antenk Electronics Co., Ltd. brings over 15 years of precision stamping and connector engineering expertise to every battery contact we produce. Unlike many competitors who offer generic male contacts with loose tolerances (±0.15mm or worse), Antenk's Model 5223 is precision-engineered with tight dimensional tolerances of ±0.05mm on all critical features, ensuring consistent performance batch after batch. While other suppliers typically demand high MOQs (10,000–20,000 pieces) and charge 500–1,000 in tooling fees for any customization, Antenk offers low MOQs starting at only 1,000 units with NO tooling fees for standard modifications – including alternative materials (beryllium copper for high-reliability applications, stainless steel for cost-sensitive projects), plating options (gold for medical/humid environments, selective gold for mixed-signal circuits, bright tin for general use), dome height adjustments (standard, raised, or low-profile), and custom tail configurations (angled, offset, extended, or SMT-ready). Unlike competitors who rely on AQL batch sampling (allowing up to 1.5% defect rate), Antenk performs 100% automated optical inspection (AOI) on every stamped contact plus rigorous testing per EIA-364 standards: contact resistance (EIA-364-06), spring force validation (EIA-364-04), insertion/withdrawal force, and 48-hour salt spray corrosion testing – double the industry standard of 24 hours. Antenk provides free engineering samples, complete 2D/3D CAD models, and responsive technical support within 24 hours. Contact Antenk today for a competitive quotation – we typically respond within 4 hours and offer sample orders for immediate evaluation. Ask about our volume discounts starting at 5,000 units!
