BATTERY Contacts FOR 'AAA' Male Battery 5225

 

Huizhou Antenk Electronics Co., Ltd. presents the BATTERY Contacts FOR 'AAA' Male Battery Model 5225, a precision-engineered conductive component specifically designed for the positive terminal (male side) of standard AAA batteries. Model 5225 features a raised button-style contact 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 a nickel or selective tin plating, this contact delivers ultra-low electrical resistance below 20 milliohms and excellent corrosion resistance. Key functional characteristics include a precision-stamped raised dome structure that provides a consistent normal force of 55–85 grams, ensuring stable electrical continuity even under vibration, thermal cycling from -25°C to +85°C, or battery expansion during discharge. The contact supports continuous currents up to 2A (fully compatible with AAA cell ratings) and features an optimized solder tail design supporting both through-hole and wire-lead termination methods. Its compact footprint is ideal for space-constrained devices, while the anti-overstress stop prevents permanent deformation during battery insertion. The product is fully RoHS, REACH, and conflict mineral compliant.

Huizhou Antenk Electronics Co., Ltd. brings over 15 years of precision stamping and connector manufacturing expertise to the battery contact industry. Unlike many competitors who offer only generic, one-size-fits-all male contacts with wide tolerances and minimal quality control, Antenk's Model 5225 is precision-engineered specifically for AAA cell geometry with tight dimensional tolerances of ±0.05mm on all critical features. While other suppliers typically demand high MOQs (10,000+ pieces) and charge expensive tooling fees for any customization, Antenk offers low MOQs starting at only 1,000 units with affordable, flexible customization options – including alternative materials (beryllium copper for high-reliability medical applications, stainless steel for cost-sensitive consumer projects), plating finishes (gold for harsh/humid environments, selective gold for mixed-signal circuits, matte tin for general purpose), dome height adjustments (standard, raised, or low-profile), and custom tail geometries (angled, offset, extended, or SMT-ready). Unlike competitors who rely on batch sampling (AQL 1.0 or higher), 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 testing, and 48-hour salt spray corrosion testing – double the industry standard of 24 hours. Antenk also provides free engineering samples, complete 2D/3D CAD models, and dedicated technical support within 24 hours. For global buyers seeking a reliable, precise, and cost-effective AAA male battery contact that outperforms generic alternatives, Model 5225 from Antenk is the superior choice.
