BATTERY Contacts FOR 'C' Negative Cell Battery 5241

Application Scope: Model 5241 is specifically designed for devices requiring C-size battery power, including portable lanterns and heavy-duty flashlights, large portable radios, children's ride-on toys, electric door locks, medical infusion pumps, gas detectors, portable humidifiers, battery-operated fans, industrial data loggers, backup power modules for security systems, and laboratory instruments – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the contact's reinforced tail via through-hole (recommended for vibration resistance) to the PCB or wire-lead termination. Ensure the spring receiving surface faces outward. Insert the C battery negative terminal (flat end) against this contact, with the positive end against a corresponding male contact. For series configurations, use multiple Model 5241 contacts. Precautions: Do not exceed 6A continuous current; avoid reverse polarity installation; operate within -40°C to +100°C range; ensure proper alignment during insertion to prevent spring over-compression – the heavy-duty spring requires more insertion force than AA contacts. Advantages Over Competitors: Unlike generic C-cell contacts made from thinner materials (0.25mm vs. our 0.35mm minimum), Antenk’s Model 5241 uses thicker gauge phosphor bronze for greater durability. Competitors often skip spring force testing for larger cells; Antenk performs 100% spring force validation per EIA-364-04. While others require 10,000+ MOQ and

800–1,500 tooling fees for C-cell tooling, Antenk offers low MOQs (1,000 units) with no tooling fees for standard modifications. Our IATF16949 certification ensures automotive-grade quality management – most C-cell contact suppliers lack this. Additionally, our 72-hour salt spray testing (triple industry standard) and 15,000-cycle validation ensure superior reliability for demanding applications.

 

Antenk’s vertical integration delivers consistent quality for Model 5241. Process flow: (1) In-house mold design and fabrication using our 180+ precision terminal molds (specific heavy-gauge tooling for C-cell contacts); (2) High-speed stamping on Japanese/Taiwanese presses (11 machines) using 0.35mm–0.5mm thick phosphor bronze strip at up to 600 strokes/minute (slower for thicker material); (3) Barrel plating (nickel/tin/gold) with real-time thickness monitoring – extended plating time for complete coverage on larger contacts; (4) 100% AOI dimensional inspection with ±0.08mm tolerance (slightly looser than AA due to larger part size, still tighter than industry average of ±0.15mm); (5) Spring force testing per EIA-364-04 – mandatory for every batch; (6) Contact resistance testing per EIA-364-06; (7) 72-hour salt spray corrosion testing (exceeds industry standard of 24-48 hours); (8) Automated assembly on 180+ machines; (9) Final QC with lot traceability and dimensional report. Our laboratory houses 20+ testing devices including profile projectors, hardness testers, environmental chambers, and a tensile/compression tester for spring force validation. With 250+ employees including dedicated engineering and QA teams, 18+ mold-making machines, and 250+ plastic injection molds, we provide free samples, complete 2D/3D CAD drawings, and 24-hour technical support.
