The **JIS (Japanese Industrial Standard)** battery standard, defined by **JIS D 5301**, is the dominant lead-acid battery specification across Asia, Africa, the Middle East, and Oceania. It is the naming and dimensional system behind the world’s highest-volume automotive battery sizes — including the 65D26, which powers millions of Japanese-brand sedans and SUVs worldwide.

Chengguang Power Tech manufactures **7 JIS models**, from the 45 Ah 55B24 to the 200 Ah 190H52. This page explains the JIS code system, the mounting hardware, and how to read a JIS model number.

## Key Takeaways

- **Code** — JIS code = performance class + size class (65D26 = 65 class, D-series width, 26 length code).
- **Mounting** — B00 top-frame clamp + T1 posts — fundamentally different from DIN B13 bottom rail.
- **Range** — 7 models from 55B24 (45 Ah) to 190H52 (200 Ah).
- **CCA note** — JIS CCA (D 5301, −15 °C) uses a different test point from SAE (−18 °C), so the two numbers are not directly convertible.

## Reading a JIS Model Number

A JIS code like **65D26** encodes three pieces of information:

| Position | Meaning | Example (65D26) |
| --- | --- | --- |
| 1–2 (numeric) | Performance class — capacity/CCA tier (higher = more power) | 65 |
| 3 (letter) | Case width class — B (narrow ~129 mm), D (wide ~173 mm), E (extra-wide ~176 mm), G/H (heavy duty) | D |
| 4–5 (numeric) | Approximate case length in centimetres | 26 (≈260 mm) |

So **65D26** = 65-class performance, D-series width, 26 cm length. **55B24** = 55-class, B-series narrow frame, 24 cm length. **190H52** = 190-class, H-series heavy-duty frame, 52 cm length.

The same physical case often carries multiple regional names. The 65D26 is sold as **NS70** in Southeast Asia/Australia, **N50** in the Middle East/Africa, and **55D26** as an economy variant — all the same 260 × 173 mm footprint. Verify the Ah and CCA on the label; a name alone does not fix the electrical spec.

## JIS Mounting Hardware

JIS batteries use a distinctive mounting system that does not interchange with DIN or BCI:

| Attribute | JIS Specification |
| --- | --- |
| Terminal | T1 post — small post (cars) or large post (heavy duty) |
| Hold-down | B00 (top frame clamp) |
| Polarity | Type [0] — left negative (−), right positive (+) |
| Standard document | JIS D 5301 |
| Test reference | CCA at −15 °C (differs from SAE −18 °C) |

A JIS B00 hold-down is a metal frame clamped across the battery top — fundamentally different from the DIN B13 bottom-rail lip. When replacing a battery, confirm the tray uses a top-frame clamp before assuming a JIS unit will fit.

## The Chengguang JIS Range: 7 Models

| Model | Also Known As | Type | C20 (Ah) | CCA (SAE) | Dimensions (mm) | Terminal | Weight (kg) |  
 |—|—|—:|—:|—|—|—:|  
 | 55B24 | N45, N40 | SLI | 45 | 370 | 238 × 129 × 202–227 | T1 small | 11–14 |  
 | 55D23 | 75D23 | SLI | 60 | 500 | 232 × 173 × 202–225 | T1 small | 13–16 |  
 | 65D26 | 55D26, NS70, N50, N50Z | SLI | 55–70 | 450–580 | 260 × 173 × 202–225 | T1 small | 14–18 |  
 | 95E41 | W105, N100 | SLI | 100 | 750 | 410 × 176 × 213–233 | T1 small | 22–26 |  
 | 105D31 | 95D31, 65D31, N90, N80, N70 | SLI | 90 | 650 | 306 × 173 × 202–225 | T1 small | 19–23 |  
 | 145G51 | N150 | Heavy Duty | 120–135 | 800–900 | 508 × 222 × 212–240 | T1 large | 30–38 |  
 | 190H52 | N200 | Heavy Duty | 200 | 1,100 | 521 × 278 × 220–270 | T1 large | 45–55 |

### Application Mapping

| Vehicle Type | Recommended JIS Models |
| --- | --- |
| Compact car / hatchback | 55B24 |
| Mid-size sedan | 55D23, 65D26 |
| Large sedan / SUV | 65D26, 95E41, 105D31 |
| Pickup / light truck | 105D31 |
| Medium truck / bus | 145G51 |
| Heavy truck / equipment | 190H52 |

### Regional Demand

| Region | Primary Standard | Top JIS Models |
| --- | --- | --- |
| Southeast Asia | JIS | 55B24, 55D23, 65D26 |
| Africa | JIS + DIN | 65D26, 95E41, 105D31 |
| Middle East | JIS + DIN | 65D26, 105D31 |
| Australia / Oceania | JIS (AS) | 65D26, 105D31 |

## Buying Considerations

1. **Width class first.** B-series (129 mm) and D-series (173 mm) trays are not interchangeable. Measure the tray width — 130 mm points to 55B24; 175 mm opens the D-series.
2. **Performance tier maps to CCA.** The leading digits are a power class, not a capacity guarantee. The 105D31/95D31/65D31 share one case but differ in Ah (90/80/65). Confirm the label rating.
3. **Heavy duty is a different animal.** 145G51 and 190H52 use thick Pb-Sb plates, deep-sump cases, and T1 large posts. They will not fit a passenger car tray (30–55 kg).
4. **JIS CCA ≠ SAE CCA.** JIS D 5301 rates CCA at −15 °C versus SAE −18 °C — different test procedures with no universal percentage conversion. Chengguang spec sheets quote SAE J537 CCA to keep comparisons consistent.

## Testing & Quality Control

JIS batteries are tested to JIS D 5301 with a 100% gate on every unit:

| Test | Estándar | Coverage |
| --- | --- | --- |
| CCA | SAE J537 at −18 °C (cross-referenced) | 100% |
| Open-circuit voltage | >12.60 V after formation | 100% |
| Visual / polarity / hold-down | JIS D 5301 | 100% |
| C20 capacity | IEC 60095-1 | Batch |
| Vibration | JIS D 5301, 3g RMS / 8 h | Batch |

## JIS Manufacturing Notes

Chengguang’s JIS line splits by duty class, not just by case size:

| Duty Class | Grid Alloy | Plate Design | Models |
| --- | --- | --- | --- |
| SLI (passenger) | Pb-Ca (calcium) | Thin plates, high surface area for CCA | 55B24, 55D23, 65D26, 95E41, 105D31 |
| Heavy duty (commercial) | Pb-Sb (antimony) | Thick plates, deep-sump case, high RC | 145G51, 190H52 |

Calcium grids cut self-discharge and water loss (the SLI requirement); antimony grids survive deep cycling and vibration (the truck/bus requirement). The same 65D26 case can be built to 55, 65, or 70 Ah by varying plate count and paste density — which is why the **label Ah, not the case name**, is the purchase specification.

## JIS Performance Classes Decoded

The leading digits of a JIS code are a performance class — a rough capacity band, not an exact Ah. The size letter and final digits then fix the case:

| Performance Class | Typical Capacity | Example Models | Vehicle Class |
| --- | --- | --- | --- |
| 50–55 | 45–60 Ah | 55B24, 55D23 | Compact cars |
| 65–75 | 65–75 Ah | 65D26, 75D23 | Mid-to-large sedans, SUVs |
| 95–105 | 90–100 Ah | 95E41, 105D31 | Large SUVs, pickups |
| 145+ | 120+ Ah | 145G51, 190H52 | Trucks, buses, equipment |

The **width class letter** is the first fitment decision: B-series (129 mm) for compact trays, D-series (173 mm) for the standard sedan/SUV tray, and E/G/H-series (176–278 mm) for large and heavy-duty cases.

## CCA by Engine Class — JIS Model Fit

| Engine | Typical CCA (SAE) | JIS Model |
| --- | --- | --- |
| 4-cyl gasoline 1.3–2.0 L | 370–500 | 55B24, 55D23 |
| V6 gasoline 2.5–3.5 L | 500–650 | 65D26, 105D31 |
| V8 gasoline >4.0 L | 650–850 | 95E41, 105D31 |
| 4-cyl diesel 2.0–3.0 L | 550–750 | 65D26, 95E41 |
| V6/V8 diesel >3.0 L | 750–1,100 | 145G51, 190H52 |

Climate adjustment: add ~20% CCA for sustained −20 °C operation; subtract ~10% for markets that never freeze. A 65D26 in Siberia is not the same sizing decision as a 65D26 in Dubai.

## JIS CCA Conversion

JIS D 5301 rates CCA at −15 °C, while SAE uses −18 °C — so the same battery carries different numbers depending on the standard on the label:

| Estándar | Test Temp | Test Basis |
| --- | --- | --- |
| SAE J537 | −18 °C | Chengguang catalog reference |
| IEC 60095-1 | −18 °C | Closely aligned with SAE |
| EN 50342-1 | −18 °C | Different pass criteria |
| DIN 43539 | −18 °C | Legacy German method |
| JIS D 5301 | −15 °C | Warmer test point |

This is why a “650 CCA” label must be read against its standard. Chengguang spec sheets quote **SAE J537 CCA** across the catalog so comparisons stay consistent — verify which standard is printed on any competitor’s label before comparing numbers.

## JIS ↔ DIN Cross-Reference

For cross-market sourcing, the closest Chengguang DIN equivalents to the JIS range (dimensional approximations — always verify hold-down and terminals):

| JIS Model | DIN Equivalent | JIS Dimensions (mm) | DIN Dimensions (mm) | Fit Match |
| --- | --- | --- | --- | --- |
| 65D26 | 56638 (DIN66) | 260 × 173 × 202–225 | 278 × 175 × 175–190 | Verify |
| 105D31 | 58043 (DIN80) | 306 × 173 × 202–225 | 315 × 175 × 175–190 | Verify |
| 95E41 | 58827 (DIN88) | 410 × 176 × 213–233 | 353 × 175 × 175–190 | Different |
| 145G51 | 60038 (DIN100) | 508 × 222 × 212–240 | 393 × 175 × 175–190 | Different |

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

## JIS D 5301 — What the Standard Actually Tests

JIS D 5301 is the governing document for Japanese automotive batteries. Beyond CCA, it prescribes the tests a JIS battery must pass:

| Test | What It Checks | Typical Requirement |
| --- | --- | --- |
| Cold-cranking (CCA) | Cranking amps at −15 °C | Model-specific rating |
| High-rate discharge | Sustained high current without voltage collapse | Voltage above threshold for duration |
| Charge acceptance | How fast the battery re-absorbs charge | Current at set voltage |
| Vibration | Survival under vehicle shaking | 3g RMS / 8 h |
| Water consumption | Electrolyte loss over life | Low loss (Ca-Ca grids) |

Chengguang tests every JIS unit to JIS D 5301 and cross-references CCA to SAE J537 (−18 °C) so spec-sheet comparisons stay consistent across standards.

## JIS vs DIN vs BCI — At a Glance

| Attribute | JIS | DIN | BCI |
| --- | --- | --- | --- |
| Code format | Performance + size (65D26) | 5-digit numeric (56638) | Group number (Group 48) |
| Hold-down | B00 top-frame clamp | B13 bottom-rail lip | Bracket/top clamp |
| Terminal | T1 post (small/large) | Standard post (∅19.5/17.9) | Side or top post |
| CCA test | −15 °C (D 5301) | −18 °C (DIN 43539 / EN) | −18 °C (SAE J537) |
| Primary markets | Asia, Africa, Middle East, Oceania | Europe + European aftermarket | América del Norte |

Chengguang manufactures JIS and DIN and cross-references BCI. The hold-down and terminal type — not the Ah rating — are what decide interchangeability.

## Preguntas frecuentes

**Is NS70 the same as 65D26?** Yes — the same physical battery. NS70 is the Southeast Asia/Australia naming, N50 is the Middle East/Africa naming, and 55D26 is the economy variant of the same 260 × 173 mm case.

**Can I upgrade from 55B24 to 65D26?** Only if the tray fits — the 65D26 is 22 mm longer and 44 mm wider than the 55B24. Measure before buying.

**What does the “D” in 65D26 mean?** The D-series width class (173 mm). B-series is 129 mm. Width class is the first fitment decision.

**Why does the same case have different Ah ratings?** The 65D26 case can be built to 55, 65, or 70 Ah by varying plate count and paste density — the label Ah, not the case name, is the purchase specification.

**What is the difference between JIS and SAE CCA?** JIS D 5301 tests at −15 °C versus SAE’s −18 °C — different test procedures, so the two numbers are not directly convertible. Chengguang quotes SAE J537 CCA for consistent comparison.
