The **DIN (Deutsches Institut für Normung)** battery standard is the lead-acid specification used across Europe and the European-brand vehicle aftermarket in Africa, the Middle East, and South America. DIN batteries use a five-digit numeric code, a B13 bottom-rail hold-down, and standard post terminals — a fundamentally different mounting system from JIS.

Chengguang Power Tech manufactures **7 DIN models**, from the 66 Ah 56638 (DIN66) to the 100 Ah 60038 (DIN100). This page explains the DIN code system, mounting hardware, and model range.

## Key Takeaways

- **Code** — DIN = five-digit code + B13 bottom rail + standard post terminals (∅19.5/+ ∅17.9/−).
- **Range** — 7 models from 56638 (DIN66, 66 Ah) to 60038 (DIN100, 100 Ah).
- **Fitment variable** — Case length spans 278 mm (DIN66) to 393 mm (DIN100) — measure the tray.
- **CCA note** — DIN 43539 and EN 50342-1 use different test procedures from SAE, so their CCA numbers are not directly convertible.

## Reading a DIN Model Number

A DIN code such as **56638** is a five-digit numeric identifier, often written with a decimal as **566.38**. Unlike JIS, the digits do not parse into performance + size in an obvious way — the code is a catalog identifier. Retailers and buyers therefore refer to DIN batteries by their **DIN size class** instead:

| DIN Code | Size Class | Capacity |
| --- | --- | --- |
| 56638 | DIN66 | 66 Ah |
| 57117 | DIN70 | 70 Ah |
| 57219 | DIN72 | 72 Ah |
| 57412 / 57413 | DIN75 | 75 Ah |
| 58043 | DIN80 | 80 Ah |
| 58827 | DIN88 | 88 Ah |
| 60038 | DIN100 | 100 Ah |

## DIN Mounting Hardware

The defining hardware feature of a DIN battery is the **B13 bottom rail**: a lip molded into the case base that slides under a rail in the vehicle tray. There is no top frame.

| Attribute | DIN Specification |
| --- | --- |
| Terminal | Standard DIN post — ∅19.5 mm positive, ∅17.9 mm negative |
| Hold-down | B13 (bottom rail lip) |
| Polarity | Type [0] — left negative (−), right positive (+) |
| Case shape | Shorter and wider than JIS equivalents |
| Standard documents | EN 50342-1, DIN 43539 (legacy CCA) |

A DIN battery will not drop into a JIS tray (B00 top-frame clamp) or a BCI tray without an adapter. When in doubt, measure the tray and check whether it has a bottom rail or a top clamp.

## The Chengguang DIN Range: 7 Models

| Model | Also Known As | Type | C20 (Ah) | CCA (SAE) | Dimensions (mm) | Terminal | Weight (kg) |  
 |—|—|—:|—:|—|—|—:|

### Size Progression

| DIN Size | Case Length (mm) | Positioning |
| --- | --- | --- |
| DIN66 | 278 | Entry level — most common European size |
| DIN70–DIN75 | ~278 (mid-range) | Step-ups in capacity within the compact case |
| DIN80 | 315 | Large-frame bridge |
| DIN88 | 353 | Luxury mid-tier |
| DIN100 | 393 | Flagship large-frame |

### Application Mapping

| Vehicle Type | Recommended DIN Models |
| --- | --- |
| Compact-to-mid European car | 56638 (DIN66) |
| Mid-size sedan / SUV | 57117–57412 (DIN70–75) |
| Large sedan / SUV | 58043 (DIN80) |
| Luxury / premium diesel | 58827 (DIN88), 60038 (DIN100) |
| Light commercial (auxiliary) | 60038 (DIN100) |

### Regional Demand

| Region | DIN Penetration | Top DIN Models |
| --- | --- | --- |
| Europe | Core market (native DIN standard) | 56638–60038, full range |
| Africa (West/North) | DIN + JIS (Francophone/European fleets) | 56638, 60038 |
| Middle East | JIS ~60% / DIN ~40% | 56638, 58043, 60038 |
| South America | JIS + DIN mixed | 58043, 58827 |
| Russia / CIS | DIN, high-CCA | 58827, 60038 |

DIN volumes concentrate where European-brand vehicles dominate — Europe itself, plus the European-vehicle segments of Africa, the Middle East, and South America.

## Buying Considerations

1. **B13 vs B00 is the first check.** European cars mount with a bottom rail; Asian cars with a top clamp. Getting this wrong means the battery physically will not stay in the tray.
2. **Length is the fitment variable.** The DIN range spans 278 mm to 393 mm. A 40 mm difference (DIN88 vs DIN100) is enough to make a battery not fit. Measure the tray length.
3. **DIN CCA reads differently.** DIN 43539 and EN 50342-1 use different test procedures from SAE J537, so their CCA numbers are not directly interchangeable. Chengguang spec sheets quote SAE J537 CCA for cross-standard comparability.
4. **The 57412/57413 variants** likely differ by terminal configuration or polarity. Confirm the variant your vehicle requires before ordering.
5. **CE documentation** for EU import is available on every Chengguang DIN model.

## Testing & Quality Control

| Test | Standard | Coverage |
| --- | --- | --- |
| CCA | SAE J537 at −18 °C | 100% |
| Open-circuit voltage | >12.60 V | 100% |
| Visual — B13 rail integrity, terminal alignment | EN 50342-1 | 100% |
| C20 capacity | IEC 60095-1 | Batch |
| Charge acceptance | EN 50342-1 | Batch |

## DIN Manufacturing Notes

| Duty | Grid Alloy | Models |
| --- | --- | --- |
| SLI (passenger) | Pb-Ca (calcium), optimized for high-rate discharge | 56638–60038 |

DIN cases are injection-molded with the B13 bottom rail formed into the base — the rail is not a separate part, which is why it cannot be “added” to convert a JIS battery. The 60038 (DIN100) uses increased plate count and Ca-Ca grids tuned for 870 A high-rate discharge, on a dedicated large-frame line (~1,000–1,500 units/day); the 56638 (DIN66) compact line runs ~1,500–2,500 units/day.

## DIN Series Decoded

DIN model numbers group into four series that track case size — the first two digits are the family:

| DIN Series | Typical Case | Models | Position |
| --- | --- | --- | --- |
| 56xxx | Compact (~278 mm) | 56638 (DIN66) | Entry — most common European size |
| 57xxx | Mid-size (~278 mm) | 57117 (DIN70), 57219 (DIN72), 57412 (DIN75) | Capacity step-ups |
| 58xxx | Large (315–353 mm) | 58043 (DIN80), 58827 (DIN88) | Luxury mid-to-large |
| 60xxx | Extra-large (393 mm) | 60038 (DIN100) | Flagship |

Unlike JIS, the digits do not parse into a clean performance + size formula — the code is a catalog identifier. In practice, European buyers select by **size class** (DIN66 → DIN100) and measure tray length, which spans 278 mm to 393 mm across the range.

## CCA by Engine Class — DIN Model Fit

| Engine | Typical CCA (SAE) | DIN Model |
| --- | --- | --- |
| 4-cyl gasoline 1.4–2.0 L | 370–500 | 56638 (DIN66) |
| 4-cyl / V6 gasoline 2.0–3.5 L | 500–650 | 57117–57412 (DIN70–75) |
| V6/V8 gasoline + light diesel | 650–850 | 58043 (DIN80) |
| Large diesel / luxury V8 | 750–1,100 | 58827 (DIN88), 60038 (DIN100) |

Note: DIN70–DIN88 CCA figures are factory-verified EN 50342-1 values; the EN CCA on the shipped label, not the size class, is the purchase specification. The 60038’s 870 A (SAE) reflects European cold-climate requirements versus the ~650–750 A of equivalent-capacity JIS units.

## DIN ↔ BCI ↔ JIS Group Mapping

For cross-market sourcing, these are the closest equivalents Chengguang maps (dimensional approximations — always verify hold-down and terminals):

| DIN Model | BCI Group | JIS Equivalent | Confidence |
| --- | --- | --- | --- |
| 56638 (DIN66) | Group 48 (H6) | 65D26 | Medium |
| 57117–57412 (DIN70–75) | Group 48 (H6) | — | Low |
| 58043 (DIN80) | Group 94R (H7) | 105D31 | Medium |
| 58827 (DIN88) | Group 49 (H8) | 95E41 | Low (length differs) |
| 60038 (DIN100) | Group 31 | 145G51 | Low (class differs) |

The recurring caveat: a B13 bottom-rail DIN battery and a B00 top-frame JIS battery of similar dimensions will **not** interchange without an adapter — hold-down is the first thing to check, not the Ah number.

## EN 50342-1 vs DIN 43539

Two different “DIN” CCA numbers circulate on European labels:

| Standard | What It Is | Test Basis |
| --- | --- | --- |
| DIN 43539 | Legacy German cold-cranking test | Legacy method |
| EN 50342-1 | Current European standard (with 10-s + 30-s discharge) | Different pass criteria |

A battery labeled “540 EN” and one labeled “540 DIN” are not the same battery — they are measured under different test procedures and are not directly interchangeable. Chengguang quotes SAE J537 CCA on spec sheets to remove this ambiguity.

## DIN Regulatory Marking & EU Compliance

European-market DIN batteries carry regulatory marks that Asian/JIS labels do not:

| Mark | Meaning | Applies To |
| --- | --- | --- |
| CE | Conformité Européenne — EU market access | All DIN models |
| EN 50342-1 | European battery standard | Performance/testing reference |
| Battery Directive (2006/66/EC) | Waste-battery take-back & recycling | EU-sold batteries |
| REACH | Chemical compliance (lead is a listed substance) | EU import |

For private-label buyers, Chengguang provides the full CE technical file and REACH declaration so the branded product clears EU customs without delay — a document set a JIS-only supplier typically cannot provide.

## DIN Fitment Verification Checklist

Before ordering a DIN battery, run this measurement sequence:

1. **Measure tray length** — 278 mm (DIN66–75), 315 mm (DIN80), 353 mm (DIN88), or 393 mm (DIN100). Length is the decisive dimension.
2. **Confirm B13 bottom rail** — the tray must have a rail the battery lip slides under. A top clamp (B00) means the vehicle is JIS, not DIN.
3. **Check terminal position** — DIN type [0] is left (−), right (+). Some variants (57412 vs 57413) reverse this.
4. **Verify post diameter** — ∅19.5 mm positive, ∅17.9 mm negative. BCI/JIS posts differ.
5. **Confirm height clearance** — 175–190 mm; a tall JIS battery will not fit under a low European bonnet.

Getting the length right but the hold-down wrong is the most common DIN fitment error — the battery physically will not lock into the tray.

## Frequently Asked Questions

**Why do DIN and JIS batteries not interchange?** DIN uses a B13 bottom-rail lip; JIS uses a B00 top-frame clamp. The mounting systems are different even when the case dimensions are similar.

**What is the most common DIN size?** DIN66 (56638) — the standard for compact-to-mid European cars such as the VW Golf and Opel Astra.

**What vehicles need DIN100?** Large European luxury diesels — Audi A8, BMW 7 Series, Mercedes S-Class — plus some light commercial auxiliary applications.

**How do I know if my car needs DIN or JIS?** Check the battery tray: a bottom-rail lip (the battery slides under a rail) = DIN B13; a metal frame clamped across the top = JIS B00. European cars are DIN; Asian-market cars are JIS.

**Does a DIN battery need CE marking for Europe?** Yes — CE marking plus the Battery Directive and REACH compliance documents are required for EU import. Chengguang supplies the full document set on every DIN model.
