Model N120 · JIS Group N120 · 12V · 120 Ah · 820 CCA
Reference spec for N120: third-party catalogs list 120 Ah, 820 A CCA (JIS) and 505×183×240 mm. Not a DINWEY stock rating.
Key Takeaways
- The N120 is a 120Ah JIS heavy-duty class — a step up from the N100 for medium trucks and construction equipment.
- Reference sources list 120Ah, 820A CCA (JIS) and 505×183×240mm.
- Third-party CCA ranges ~800–900A and height varies 208–257mm across makers — confirm before ordering.
- This is a reference specification, not a DINWEY published stock rating.
The N120 is a 120Ah JIS heavy-duty starting battery for medium trucks, buses and construction equipment — a reference model compiled from third-party catalogs.
The N120 class has a longer 505mm case than the N100's 410mm, giving more plate area and higher capacity (120Ah) and cold-cranking (~820A CCA). Sebang lists 120Ah at 820A CCA.
As a reference specification, exact values vary by manufacturer — confirm your tray and rating before replacement.
