65D26 Battery (NS70/N50/55D26): Specs, Fitment, and Cross-Reference
Part of the 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.

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:
- Warm climate. A 3.0 L diesel needs ~550–650 CCA. The 65D26’s top tier (580 A) covers warm-climate diesel starts comfortably.
- 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.
