105D31 Battery (95D31/N90/N80/N70): Specs, Fitment, and Cross-Reference
Part of the JIS Battery Standard guide.
The 105D31 is the largest JIS D-series battery in the Chengguang range — a high-capacity, high-CCA model for large SUVs, light commercial vehicles, and demanding diesel applications. It is the direct upgrade from the 65D26: 46 mm longer, 90 Ah capacity, and 650 CCA.
Key Takeaways
- Specs — 90 Ah, 650 CCA in a 306 × 173 mm case — 46 mm longer than the 65D26.
- Case family — 65D31/95D31/105D31 and N70/N80/N90 share one case at different capacity tiers.
- Fitment — Toyota Prado/Hilux diesel, Ford Ranger, Isuzu D-Max.
- Cross-reference — BCI Group 27; DIN equivalent 58043 (DIN80) — verify hold-down.
- Build — Ca-Ca grid with tin additive, PE separator, COS welding, heat-sealed cover, 2,000–3,000 units/day.

Case & Terminal Identification
Standard D-series width (173 mm) with an extended 306 mm length — 46 mm longer than the 65D26. That extra length is the primary distinguishing mark. The label carries multiple designations by capacity tier:
| Label | Region | Capacity Class |
|---|---|---|
| 105D31 | Most global markets | 90 Ah |
| 95D31 | Some markets | 80 Ah |
| 65D31 | Economy variant | 65 Ah |
| N70 / N80 / N90 | Middle East / Africa | 70 / 80 / 90 Ah |
All share the same 306 × 173 mm case. The N-series names indicate capacity tiers within one physical size — verify the Ah rating on the label.
تطبيقات المركبات
Large SUVs, light commercial vehicles, and diesel pickups — for 90 Ah capacity and 650 CCA, especially diesel engines up to ~4.0 L.
| Brand | Compatible Models |
|---|---|
| Toyota | Land Cruiser Prado (all gen), Hilux (diesel, esp. 3.0 L D-4D), Fortuner (diesel) |
| Nissan | Navara (diesel), Pathfinder (diesel), Patrol (petrol) |
| Mitsubishi | Triton/Strada (diesel), Pajero (diesel) |
| Ford | Ranger (Asian diesel, esp. 3.2 L) |
| Mazda | BT-50 (diesel) |
| Isuzu | D-Max (3.0 L diesel — verify tray length) |
Fitment is a market-based guide — confirm the tray accepts the extra 46 mm over the 65D26.
Regional Markets
| Region | Demand | ملاحظات |
|---|---|---|
| Africa | ★★★★★ | Top seller for SUVs and light trucks |
| Middle East | ★★★★ | Popular in GCC for large SUVs |
| Southeast Asia | ★★★ | Diesel pickup segment (Thailand, Philippines) |
| South America | ★★★ | Growing diesel demand |
| أستراليا | ★★ | Diesel 4×4 segment |
Manufacturing & Grid Alloy
The 105D31 runs on Chengguang’s D-series extended-frame line in Jinzhou, Hebei, China:
- Grid alloy — calcium-calcium (Ca-Ca) with a tin additive for corrosion resistance.
- Plate design — optimized paste density for high-rate discharge (650 CCA).
- Assembly — automated plate enveloping with PE separator; COS (Cast-On-Strap) welding for robust intercell connections.
- Cover — heat-sealed polypropylene with labyrinth venting (maintenance-free).
- Throughput — 2,000–3,000 units/day across all brand labels.
Testing & Quality Control
| اختبار | قياسي | Pass Criteria | Coverage |
|---|---|---|---|
| CCA Cold Cranking | SAE J537 at −18 °C | >650 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 90 Ah | Batch (1:500) |
| Reserve Capacity | SAE J537 | 25 A to 10.5 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. The 90 Ah capacity provides some buffer against heat-accelerated aging.
Sizing Check — Worked Example
A 3.2 L Ford Ranger diesel in a cold market shows why the 105D31 exists:
- Cold start. A 3.2 L diesel needs 630–700 CCA. The 105D31’s 650 CCA clears it; at −20 °C apply the ~20% margin (650 × 1.2 ≈ 780 CCA) and verify against the engine’s published spec — for sustained cold markets the next step is a dual-battery or heavy-duty setup.
- Accessory load. 90 Ah at a 9 A load (winch + lights + fridge) ≈ 10 hours to full discharge, or ~5 hours to the 50% depth-of-discharge line.
Cross-Reference
| Model | قياسي | Relationship |
|---|---|---|
| 95D31 | JIS | Same case, 80 Ah tier |
| 65D31 | JIS | Same case, economy variant (~65 Ah) |
| N70 / N80 / N90 | JIS | Regional naming, 70/80/90 Ah classes |
N-series designations differ in plate count and paste density within the same case — always check the label Ah and CCA.
Cross-Standard Equivalents
| قياسي | Model | Confidence | Note |
|---|---|---|---|
| BCI | Group 27 | Medium | Verify terminal type |
| DIN | 58043 (DIN80) | 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.
