DINWEY 245H52 (N220) — Largest JIS Heavy-Duty Battery (Reference)
Model 245H52 · JIS Group N220 · 12V · 220 Ah · 1200 CCA
Reference spec for 245H52 (N220): third-party catalogs list 220 Ah, 1200 A CCA (JIS) and 515×265×216 mm. Not a DINWEY stock rating.
Key Takeaways
- The 245H52 (N220) is the largest JIS heavy-duty class — a 220Ah battery that steps above the N200 (190H52).
- Reference sources (UPLUS, Powsea) list 220Ah, 1200A CCA (JIS) and 515×265×216mm.
- It is a capacity and CCA step above the N200, for the largest engines and coldest climates.
- This is a reference specification, not a DINWEY published stock rating — confirm before ordering.
The 245H52 (JIS N220) is the largest class in the JIS heavy-duty range — a 220Ah battery for the largest trucks, cold-climate starting and prime diesel generators. It is a reference model compiled from third-party catalogs.
The N220 steps above the N200 (190H52): UPLUS lists 220Ah (C20), 456 minutes reserve capacity and 1200A CCA in a 515×265×216mm case. That is a meaningful capacity and cranking step for the heaviest duty.
As a reference specification, exact values vary by manufacturer — confirm your tray and rating before replacement.

Understanding This Model's Specifications
CCA is measured to JIS D5301. UPLUS lists 1200A; Powsea also lists the 245H52 as 12V 220Ah. Third-party CCA for this class is the highest in the JIS range.
Reserve Capacity of 456 minutes (SAE J537) is the largest engine-off buffer in the JIS range — for heavy lighting, telematics and refrigeration loads.
The 515×265×216mm figure (total height 254mm with terminals) is representative. Confirm your tray length, width and height before upgrading from an N200.
Typical Applications
- Largest heavy-duty trucks
- Cold-climate starting
- Prime diesel generators
- High electrical load fleets
Vehicle Fitment
This is a third-party reference specification for the N220 (245H52) — 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.
Frequently Asked Questions
What is the 245H52 / N220 battery?
The 245H52 is the JIS N220-class 12V, 220Ah starting battery — the largest JIS heavy-duty class, above the N200.
Is the N220 a DINWEY stock battery?
