105D31 Battery — 95D31 / 65D31 / N90 / N80 / N70
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 for vehicles requiring more starting power: 46 mm longer, 90Ah capacity, and 650 CCA.

How to Identify This Battery
Standard D-series width (173 mm) with extended length — 306 mm vs 260 mm on the 65D26. This 46 mm extra length is the primary distinguishing mark. Part of the 105D31/95D31/65D31 case family. The top label may show any of these designations:
| Label | Region | Equivalent Capacity |
|---|---|---|
| 105D31 | Most global markets | 90Ah |
| 95D31 | Some markets | 80Ah class |
| 65D31 | Economy variant | 65Ah class |
| N70 | Middle East/Africa | 70Ah class |
| N80 | Middle East/Africa | 80Ah class |
| N90 | Middle East/Africa | 90Ah class |
All share the same 306 x 173 mm case dimensions. The N-series names (N70/N80/N90) indicate different capacity tiers within the same physical size — verify the Ah rating on the label.
Vehicle Applications
Large SUVs, light commercial vehicles, diesel pickups. For applications requiring 90Ah capacity and 650 CCA — particularly diesel engines up to approximately 4.0L displacement.
Compatible Vehicles

| Ford | Ranger (Asian market diesel, especially 3.2L) |
| Mazda | BT-50 (diesel) |
| Isuzu | D-Max (3.0L diesel — verify tray length) |
Fitment Verification
Vehicle fitment is a general guide based on market experience. Always verify your vehicle's battery tray dimensions (306 x 173 mm), terminal position (L-/R+), and hold-down type (B00). The 105D31 is 46 mm longer than the common 65D26 — confirm your tray can accommodate the extra length.

Frequently Asked Questions
What is the difference between 105D31 and 65D26?
The 105D31 is 46 mm longer (306 vs 260 mm) with significantly higher capacity (90Ah vs 65Ah) and CCA (650A vs 550A). It only fits vehicles whose battery tray can accommodate the extra length. It is the most common upgrade for diesel vehicles that need more starting power than a 65D26 can provide.
What do N70, N80, N90 mean?
These are regional marketing designations used primarily in the Middle East and Africa. N70 = 70Ah class, N80 = 80Ah class, N90 = 90Ah class. All share the same 105D31 case dimensions (306 x 173 mm). The difference is internal — plate count, paste density, and electrolyte volume vary to achieve different capacity/CCA targets. Always verify the Ah and CCA on the label.
For what diesel engines is 105D31 recommended?
Gasoline and diesel engines up to approximately 4.0L displacement in SUVs and pickups. Common applications: Toyota 3.0L D-4D (Hilux/Fortuner), Nissan 2.5L YD25 (Navara), Mitsubishi 2.5L/3.2L Di-D (Triton/Pajero), Ford 3.2L Duratorq (Ranger). For larger diesel engines (trucks/buses), use heavy-duty models such as 145G51 or 190H52.
How long does a 105D31 battery last?
Temperate climates: 3-5 years. Hot climates (Middle East, Africa): 18-30 months. The 105D31's higher capacity provides some buffer against heat-accelerated aging compared to smaller batteries. Regular charging system checks extend life.
Can I use a 105D31 in place of a 95E41?
Not directly interchangeable. While both are ~90-100Ah class, the 95E41 is significantly longer (410 mm vs 306 mm) and slightly wider (176 mm vs 173 mm). Different vehicles require different case sizes. Measure your tray — the 105D31 fits where the 95E41 does not, and vice versa.
