BATTERY Contacts FOR Battery 5250

Application Scope: Model 5250 is ideal for devices where battery size may vary by market or where manufacturers use the same device platform with different battery configurations, including universal battery testers, adjustable battery holders, educational electronics kits, portable power banks with swappable battery adapters, emergency backup lights, multi-function remote controls, laboratory power supplies, battery charging stations, and DIY electronics projects – markets where Antenk already supplies customers in the USA, Germany, South Korea, India, Russia, and beyond. Usage Method: Solder the contact's tail via through-hole or SMT to the PCB. The extended spring arm will automatically accommodate the inserted battery length. For best results, pair with a corresponding Model 5250 contact for the opposite terminal. For AA/AAA batteries, ensure the spring arm is compressed at least 2mm; for C/D batteries, compression of 3–3.5mm is optimal. Precautions: Do not exceed 8A continuous current; avoid inserting batteries larger than D size; do not over-compress the spring beyond 4mm total travel; operate within -40°C to +100°C range; verify proper polarity before final assembly. Advantages Over Competitors: Unlike competitors who sell separate contacts for each battery size (requiring customers to stock 4+ different part numbers), Antenk’s Model 5250 is a universal solution that reduces inventory costs by up to 75%. Competitors often use thinner 0.20mm spring material that fatigues quickly with larger batteries; Antenk uses 0.30mm phosphor bronze with a specially designed variable-thickness spring arm. While others require separate tooling for each battery type (minimum $2,000+ total investment), Antenk offers one contact for all standard cylindrical batteries with low MOQs (1,000 units) and no tooling fees. Our IATF16949 certification ensures automotive-grade quality management. Additionally, our 72-hour salt spray testing and 20,000-cycle validation ensure superior reliability even with frequent battery changes across different cell sizes.

 

Antenk’s vertical integration delivers consistent quality for Model 5250. Process flow: (1) In-house mold design and fabrication using our 180+ precision terminal molds (specialized universal tooling with extended spring geometry); (2) High-speed stamping on Japanese/Taiwanese presses (11 machines) using 0.30mm phosphor bronze strip – the variable-thickness design requires a 20+ station progressive die; (3) Barrel plating (nickel/tin/gold) with real-time thickness monitoring – uniform coating required across the entire spring arm for consistent conductivity; (4) 100% AOI dimensional inspection with critical tolerance of ±0.10mm on spring arm length and contact point position; (5) Spring force testing per EIA-364-04 at multiple compression depths (2mm, 3mm, and 3.5mm) to ensure consistent force across all battery sizes; (6) Contact resistance testing per EIA-364-06 at different compression levels; (7) 72-hour salt spray corrosion testing; (8) Automated assembly on 180+ machines with spring travel validation; (9) Final QC with lot traceability and full dimensional report including spring force curve data. Our laboratory houses 20+ testing devices including profile projectors, hardness testers, environmental chambers, and a computerized tensile/compression tester for spring force profiling. 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 showing the full spring travel range, and 24-hour technical support.
