## Inside the Manufacturing Line

A Chengguang OEM battery passes five manufacturing stages — each audited under IATF 16949 with full batch traceability:

| Stage | Process | Key Control |
| --- | --- | --- |
| 1. Grid casting | Pb-Ca or Pb-Sb alloy gravity-cast at 480–520 °C | Alloy verified per melt (spectrometer), grid weight ±2% |
| 2. Plate pasting | PbO paste onto grids, double-sided, continuous belt | Paste density 4.0–4.3 g/cm³, thickness ±0.05 mm |
| 3. Curing | 24–72 h multi-zone (35–85 °C, 95%+ RH) | Free lead <2%; 3BS for SLI, 4BS for heavy-duty |
| 4. Formation | 18–48 h multi-step charge (water-bath cooled) | Efficiency >85%, final SG 1.275–1.285 |
| 5. Final test | 100% CCA, OCV, leak, visual, weight | Every battery tested — no sampling release |

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

In-process inspection is gated at every stage:

| Production Stage | Inspection | Frequency | Стандартный |
| --- | --- | --- | --- |
| Grid casting | Alloy composition, grid weight, dimensional | Per melt lot | IATF 16949 |
| Paste mixing | Density, penetration | Per batch | Internal |
| Plate pasting | Thickness, surface quality | Continuous (inline) | Internal |
| Curing | Free lead, crystal structure, strength | Per chamber load | Internal |
| Assembly | Plate alignment, weld quality | 100% visual | IATF 16949 |
| Formation | Cell voltage, specific gravity | 100% | IEC 60095-1 |
| Final test | CCA, OCV, leak, visual, weight | 100% | SAE J537 |

## Quality Control: 100% Testing

Chengguang ships **no battery that has not been individually tested**:

| Gate | Coverage | Pass Criterion |
| --- | --- | --- |
| CCA cold-cranking | 100% | Sustained 30 s above 7.2 V at −18 °C |
| Open-circuit voltage | 100% | >12.60 V after formation |
| Leak test | 100% | No pressure loss at 2–3 psi |
| Visual / label / polarity | 100% | Case, terminals, label, seal |
| Weight | 100% | Within spec (catches missing electrolyte/plates) |
| C20 / RC / charge acceptance / vibration | Batch (1:500–2000) | Per IEC 60095-1, SAE J537, EN 50342-1 |

Every battery’s test data is stored for 5 years, and each shipment lot ships with a **Certificate of Analysis (CoA)**, MSDS, and DG declaration (UN 2794 / Class 8).

## Regional Market Intelligence

Chengguang’s OEM program is shaped by eight export regions with distinct standards and demand:

| Region | Стандартный | Top Models | Notes |
| --- | --- | --- | --- |
| Africa (#1) | JIS (E/S) + DIN (W/N) | 65D26, 55D23, DIN66–100 | 30–40M units/yr import, 12–18 mo life (heat + rough roads) |
| Middle East (#2) | JIS 60% / DIN 40% | 65D26, 105D31, DIN100 | 40–50 °C summers, 18–24 mo life |
| Southeast Asia | JIS ~100% | 55B24, 55D23, 65D26 | ~80M fleet, price-sensitive |
| Европа | DIN | DIN66–100 + AGM/EFB | Start-stop mandates; CE + REACH |
| Северная Америка | BCI | Cross-ref only | Anti-dumping duties 50–100%+ |
| South America | JIS + DIN mixed | 105D31, DIN models | Spanish labeling |
| Австралия | JIS (AS) | 65D26, 105D31 | 2–3 yr life (heat) |
| Russia / CIS | DIN | High-CCA DIN | Extreme cold, sanctions check |

This regional spread is why a private-label buyer’s first question should be **“which standard and models does my market need?”** — Chengguang sizes the OEM program around that answer.

## Payment & Logistics

| Item | Term |
| --- | --- |
| Payment | T/T (30% deposit, 70% before shipment); L/C at sight for established accounts |
| Incoterm | FOB Tianjin/Xingang (standard); CIF/CFR on request |
| Export packaging | DG-compliant, UN 2794 / Class 8 |
| Per-shipment documents | CoA, MSDS, DG declaration, packing list, Certificate of Origin, commercial invoice |

Every shipment carries a full document set — 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.

## Buyer’s Due-Diligence Checklist

When vetting a battery OEM (Chengguang or any competitor), run this checklist — each item separates a real IATF 16949 manufacturer from a trading company:

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

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

## From Trading to Manufacturing Partnership

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:

| Sourcing Model | What You Get | What You Miss |
| --- | --- | --- |
| Trading company | Convenience, mixed sourcing | No control over alloy/paste/formation |
| Direct OEM (Chengguang) | Spec control, traceability, direct pricing | Requires MOQ + spec work |

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 — which is what a private-label brand needs to defend its market position long-term.

## Frequently Asked Questions

**What is the minimum order quantity (MOQ)?** MOQ scales with customization depth — see the MOQ table above. Standard factory-label product ships by the 20 ft container (~400–600 batteries); custom-label runs start at 200–500 per model; full custom (case + terminals + spec) starts at 2,000–5,000 per model. Samples are separate — 5–20 branded units regardless of production MOQ.

**Can you match an existing battery I already sell?** Yes — 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.

**Do you supply CE documentation for Europe?** Yes — CE marking documentation is available on all DIN models for EU import.

**What is the lead time?** Samples in 3–4 weeks after spec sign-off; mass production 4–8 weeks after sample approval; shipping 2–6 weeks depending on destination.

**Can I specify a higher CCA within the same case?** Yes — 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.

**What warranty does Chengguang offer on OEM batteries?** Warranty terms are agreed per contract and market — typically 12–24 months — with claims supported by the batch traceability record and CoA. Contact Chengguang for a term sheet matched to your region.

**Can Chengguang match a competitor’s battery?** Yes — send the target model, CCA, Ah, dimensions, and terminal, and engineering maps it to the closest Chengguang platform or confirms a custom build.
