Model 56638 · DIN Group DIN66 · 12V · 66 Ah · Not published CCA
Reference spec for 56638 (DIN66): third-party catalogs list 66 Ah and 278×175×190 mm; EN cold-cranking not published. Not a DINWEY stock rating.
Key Takeaways
- The 56638 is the DIN66 class — a 66Ah European-format battery for light commercial vehicles and vans.
- Reference sources list 66Ah at 278×175×190mm; EN cold-cranking is NOT published in a single authoritative source for this size.
- DIN66 shares the 278mm length class with DIN74, but at lower capacity.
- This is a reference specification, not a DINWEY published stock rating.
The 56638 (DIN66) is a 66Ah European-format battery for light commercial vehicles and vans — a reference model compiled from third-party catalogs.
The DIN66 class is defined by its 278mm case length. King Power and Xiamen Songli both list the 56638 at 66Ah (C20) in a 278×175×190mm case.
As a reference specification, exact values vary by manufacturer. Notably, EN cold-cranking is not published in a single authoritative source for this size — we leave it unstated rather than guess.

Understanding This Model's Specifications
EN cold-cranking (EN 50342-1) is not published in a single authoritative source for the DIN66 size — left unstated here rather than interpolated. Most DIN66 batteries sit in the ~500–600A EN range, but confirm the specific datasheet.
Capacity is 66Ah at the 20-hour rate (C20). The DIN66 shares the 278mm length class with the DIN74, but holds less capacity.
Dimensions of 278×175×190mm are representative (King Power reports 278×174×189mm). Confirm your tray and terminal type (European conical T1) before replacement.
Typical Applications
- European light/medium commercial vehicles
- Vans
- Buses
Vehicle Fitment
This is a third-party reference specification for the DIN66 (56638) — 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.
