DINWEY 65D31R (N70) — Light/Medium Truck Battery (Reference)
Model 65D31R · JIS Group N70 · 12V · 70 Ah · 580 CCA
Reference spec for 65D31R (N70): third-party catalogs list 70 Ah, 580 A CCA (JIS) and 306×173×225 mm. Not a DINWEY stock rating.
Key Takeaways
- The 65D31R is the JIS N70 class — the smaller, lighter end of the heavy-duty JIS range, for light/medium trucks rather than large semi trailers.
- This is a reference specification — third-party catalogs list 70Ah, 580A CCA (JIS) and 306×173×225mm, NOT a DINWEY published stock rating.
- The N70 shares the BCI Group 27 envelope — a common fitment for Japanese light trucks and SUVs.
- At 70Ah and 118 minutes reserve capacity it suits single-battery 12V light diesel, not a 24V twin-battery heavy truck.
The 65D31R (JIS N70) is the smaller end of the JIS heavy-duty range — a 70Ah starting battery for light trucks, buses and light commercial diesel. It is a reference specification compiled from independent catalogs, not a DINWEY published stock rating.
The N70 class is defined by its case size (a 306mm-long Group-27 envelope), and the 65D31R is the specific model code. Third-party sources — BRAVA and Western Battery — list 70Ah at 580A CCA, with minor case-height differences between makers.
Because this is a reference model, exact CCA, capacity and dimensions must be confirmed against your specific supplier and tray before ordering.

Third-party reference specification — NOT a DINWEY published stock rating. Values are compiled from independent catalogs and vary by manufacturer; confirm exact CCA, capacity and dimensions before replacement.
Understanding This Model's Specifications
CCA is measured to JIS D5301. BRAVA lists 580A (JIS) at 70Ah; Western Battery lists 600A (EN) at 304×173×200mm — these are different test standards and are not directly interchangeable.
Reserve Capacity of 118 minutes (SAE J537) is the buffer for lights, telematics and a failed alternator with the engine off.
The 306×173×225mm figure is the BCI Group 27 maximum envelope; individual makers vary the case height between roughly 200mm and 225mm. Confirm the actual tray before replacement.
Typical Applications
- Light to medium trucks and light commercial diesel
- Buses and minibuses
- SUVs and 4×4 vehicles with JIS trays
- Standby generators and smaller commercial fleets
Vehicle Fitment
This is a third-party reference specification for the N70 (65D31R) — NOT a DINWEY published stock rating. Whether it fits a specific vehicle depends on the vehicle's battery standard, group size, terminal type, polarity and tray dimensions, which vary by model and generation. Always confirm the exact configuration in your vehicle manual before replacement.
