> Part of the **[JIS Battery Standard](/ar/jis-battery-standard/)** guide.

The 65D26 is the **highest-volume JIS automotive battery model globally**. Marketed as NS70, N50, and 55D26 in different regions, it powers mid-to-large Japanese sedans, SUVs, and light pickups across Africa, the Middle East, Southeast Asia, and Oceania. Its 260 × 173 mm footprint with T1 terminals is the de facto aftermarket standard for Asian-brand vehicles.

## Key Takeaways

- **Specs** — The highest-volume JIS model: 55–70 Ah, 450–580 CCA in a 260 × 173 mm case.
- **Aliases** — Same battery as NS70/N50/N50Z (regional names) and 55D26 (economy variant).
- **Fitment** — Toyota Camry/RAV4/Hilux, Honda CR-V, Nissan X-Trail — mid-to-large Asian sedans and SUVs.
- **Cross-reference** — BCI Group 48 (H6); DIN equivalent 56638 (DIN66) — verify hold-down before substituting.
- **Build** — Dedicated line, 8,000–10,000 units/day, Ca-Ca radial grid, COS welding, heat-sealed cover.

## Case & Terminal Identification

The 65D26 is a JIS D-series case: 260 mm long × 173 mm wide with T1 small-post terminals. The same physical battery carries multiple labels by market:

| Label | Region |
| --- | --- |
| 65D26 | Most global markets |
| NS70 | Southeast Asia, Australia |
| N50 | Middle East, Africa |
| N50Z | High-CCA variant (some markets) |

Verify by measuring 260 mm length, T1 terminals, L−/R+ polarity. The 65D26 is often confused with the shorter 55D23 (232 mm) — the 28 mm length difference is the key mark.

## تطبيقات المركبات

Mid-to-large sedans (2.0–3.5 L), mid-size SUVs, and light pickups — the most versatile size in the JIS lineup.

| Brand | Compatible Models |
| --- | --- |
| Toyota | Camry (all gen), RAV4, Fortuner, Hilux (diesel up to 3.0 L), Innova |
| Honda | CR-V, Accord, Civic (some), Odyssey |
| Nissan | X-Trail, Teana, Patrol (petrol), Navara (some), Qashqai |
| Mazda | CX-5, Mazda 6, BT-50 |
| Mitsubishi | Pajero Sport, Montero, Triton/Strada, Outlander |
| Isuzu | D-Max, MU-X |
| Ford | Ranger (Asian market), Everest |

Fitment is a market-based guide — verify tray (260 × 173 mm), terminal position (L−/R+), and hold-down (B00) before ordering.

## Regional Markets

## Manufacturing & Grid Alloy

The 65D26 is the **highest-volume production model** at Chengguang Power Tech (Jinzhou, Hebei, China):

- **Dedicated line** — automated plate enveloping, COS (Cast-On-Strap) welding, heat-seal cover.
- **Throughput** — 8,000–10,000 units/day across all brand labels.
- **Grid alloy** — calcium-calcium (Ca-Ca) for maintenance-free operation with low water loss.
- **Plate design** — radial grid pattern for uniform current distribution.
- **Traceability** — every battery’s formation data, CCA result, and assembly timestamp stored for 5 years.

## Testing & Quality Control

| اختبار | قياسي | Pass Criteria | Coverage |
| --- | --- | --- | --- |
| CCA Cold Cranking | SAE J537 at −18 °C | >450 A at 30 s, >7.2 V | 100% |
| Open Circuit Voltage | — | >12.60 V after formation | 100% |
| High-Rate Discharge | 30-second test | Voltage stability | 100% |
| Visual Inspection | — | Case, terminals, label, polarity | 100% |
| C20 Capacity | IEC 60095-1 | ≥95% of rated Ah | Batch (1:500) |
| Reserve Capacity | SAE J537 | 25 A to 10.5 V | Batch (1:500) |
| Charge Acceptance | IEC 60095-1 | Current at 14.4 V | Batch (1:500) |
| Vibration | JIS D 5301 | 3g RMS, 8 hours | Batch (1:2000) |
| Thermal Cycling | −30 °C to +60 °C | No leakage, CCA retention | Type approval |

## Charging & Service Life

- **Charge voltage** — SLI absorption 14.4–14.8 V; alternator output 13.8–14.4 V in service.
- **Service life** — 3–5 years temperate; **18–30 months in hot climates (35–45 °C)**, where heat is the dominant aging factor.

## Sizing Check — Worked Example

A 3.0 L diesel pickup (Hilux-class) shows why the 65D26 is the default, not a compromise:

1. **Warm climate.** A 3.0 L diesel needs ~550–650 CCA. The 65D26’s top tier (580 A) covers warm-climate diesel starts comfortably.
2. **Cold-winter market (−20 °C).** Apply the ~20% cold-weather margin: 580 × 1.2 ≈ **696 CCA** — beyond the 65D26’s ceiling. Step up to the 105D31 (650 CCA, but in a longer case) or specify the N50Z high-CCA variant if the tray is fixed at 260 mm.

Runtime arithmetic: 65 Ah (C20) at a 6.5 A accessory load = ~10 hours to full discharge; keep above ~50% depth of discharge to protect cycle life.

## Cross-Reference

| Model | قياسي | Relationship |
| --- | --- | --- |
| 55D26 | JIS | Same case, lower capacity (~55 Ah) — economy variant |
| NS70 | JIS | Same battery — SE Asia/Australia naming |
| N50 | JIS | Same battery — Middle East/Africa naming |
| N50Z | JIS | High-CCA variant, same case |

## Cross-Standard Equivalents

| قياسي | Model | Confidence | Note |
| --- | --- | --- | --- |
| BCI | Group 48 (H6) | Medium | Verify terminal type |
| DIN | 56638 (DIN66) | Verify | B00 vs B13 hold-down |

> Cross-standard matches are dimensional approximations only — electrical specs differ by standard and test method. Always verify tray dimensions, terminal type, and hold-down (B00 vs B13) before substituting.

## الأسئلة الشائعة

**Is NS70 the same as 65D26?** Yes — NS70 (SE Asia/Australia) and N50 (Middle East/Africa) are the same 260 × 173 mm battery; 55D26 is the economy variant (~55 Ah).

**What BCI group replaces a 65D26?** Group 48 (H6) is the closest BCI match; DIN 56638 (DIN66) is the European equivalent. Verify hold-down (B00 vs B13).

**Can I upgrade from 55D23 to 65D26?** Yes, if the tray has 260 mm of length — 28 mm more than the 55D23.

**How long does a 65D26 last?** 3–5 years temperate; 18–30 months in hot climates. Alternator checks (13.8–14.4 V) extend life significantly.
