    LCL (less-than-container-load) is available for trial orders. Samples are separate<\/strong> from production MOQ: 5\u201320 branded sample units are produced in 3\u20134 weeks so you can validate in your market before committing to a production run. Model mixing in one container is standard practice \u2014 SLI, heavy-duty, JIS, and DIN units ship together.<\/p>\n

    Inside the Manufacturing Line<\/h2>\n

    A Chengguang OEM battery passes five manufacturing stages \u2014 each audited under IATF 16949 with full batch traceability:<\/p>\n\n\n\n\n\n\n\n\n\n
    Stage<\/th>\nProcess<\/th>\nKey Control<\/th>\n<\/tr>\n<\/thead>\n

    The four variables that decide real-world battery life \u2014 grid alloy, paste formulation, curing profile, and formation \u2014 are all documented and traceable per heat lot, which is exactly what IATF 16949 requires.<\/p>\n

    Regional Market Intelligence<\/h2>\n

    Chengguang’s OEM program is shaped by eight export regions with distinct standards and demand:<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

    This regional spread is why a private-label buyer’s first question should be “which standard and models does my market need?”<\/strong> \u2014 Chengguang sizes the OEM program around that answer.<\/p>\n

    Every shipment carries a full document set \u2014 Certificate of Analysis (CCA, capacity, voltage per batch), MSDS, batch traceability report (raw-material lot to container), packing list, and Certificate of Origin for import duty.<\/p>\n

    Buyer’s Due-Diligence Checklist<\/h2>\n

    When vetting a battery OEM (Chengguang or any competitor), run this checklist \u2014 each item separates a real IATF 16949 manufacturer from a trading company:<\/p>\n

      \n
    1. Visit or video-audit the line<\/strong> \u2014 a real factory shows grid casting, pasting, curing, formation, and final test under one roof.<\/li>\n
    2. Verify the IATF 16949 certificate number<\/strong> against the IATF database.<\/li>\n
    3. Request traceability proof<\/strong> \u2014 a sample batch trace from raw-lead lot to container, not just a claim.<\/li>\n
    4. Confirm 100% vs batch testing<\/strong> \u2014 the final gate must be 100% CCA + OCV on every battery, not sampling.<\/li>\n
    5. Check export documentation<\/strong> \u2014 CoA, MSDS, DG (UN 2794), and CE\/REACH for EU \u2014 should be standard, not an upsell.<\/li>\n<\/ol>\n

      A trading company can source a container of batteries; only a manufacturer can prove the grid alloy, paste, curing, and formation behind them.<\/p>\n

      From Trading to Manufacturing Partnership<\/h2>\n

      Many buyers start sourcing batteries through a trading company, then graduate to working directly with a manufacturer. The transition matters because each layer adds cost and removes technical control:<\/p>\n\n\n\n\n\n\n
      Sourcing Model<\/th>\nWhat You Get<\/th>\nWhat You Miss<\/th>\n<\/tr>\n<\/thead>\n
      Trading company<\/td>\nConvenience, mixed sourcing<\/td>\nNo control over alloy\/paste\/formation<\/td>\n<\/tr>\n
      Direct OEM (Chengguang)<\/td>\nSpec control, traceability, direct pricing<\/td>\nRequires MOQ + spec work<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

      Working directly with an IATF 16949 manufacturer means the grid alloy, paste formulation, curing profile, and formation are specified by you and documented per heat lot \u2014 which is what a private-label brand needs to defend its market position long-term.<\/p>\n

      Preguntas frecuentes<\/h2>\n

      What is the minimum order quantity (MOQ)?<\/strong> MOQ scales with customization depth \u2014 see the MOQ table above. Standard factory-label product ships by the 20 ft container (~400\u2013600 batteries); custom-label runs start at 200\u2013500 per model; full custom (case + terminals + spec) starts at 2,000\u20135,000 per model. Samples are separate \u2014 5\u201320 branded units regardless of production MOQ.<\/p>\n

      Can you match an existing battery I already sell?<\/strong> Yes \u2014 provide the target model, CCA, Ah, dimensions, and terminal, and the engineering team maps it to the closest Chengguang platform or confirms a custom build.<\/p>\n

      Do you supply CE documentation for Europe?<\/strong> Yes \u2014 CE marking documentation is available on all DIN models for EU import.<\/p>\n

      What is the lead time?<\/strong> Samples in 3\u20134 weeks after spec sign-off; mass production 4\u20138 weeks after sample approval; shipping 2\u20136 weeks depending on destination.<\/p>\n

      Can I specify a higher CCA within the same case?<\/strong> Yes \u2014 plate count, paste density, and electrolyte volume are tuned to hit your CCA\/Ah target within a standard case envelope. This is how N70\/N80\/N90 tiers share one case.<\/p>\n

      What warranty does Chengguang offer on OEM batteries?<\/strong> Warranty terms are agreed per contract and market \u2014 typically 12\u201324 months \u2014 with claims supported by the batch traceability record and CoA. Contact Chengguang for a term sheet matched to your region.<\/p>\n

      Can Chengguang match a competitor’s battery?<\/strong> Yes \u2014 send the target model, CCA, Ah, dimensions, and terminal, and engineering maps it to the closest Chengguang platform or confirms a custom build.<\/p>\n
