Standards & measurement context

Naming standard	BCI/SAE
CCA basis	SAE J537 (−18°C)

The CCA figure is defined by its test standard — values from different standards are not directly interchangeable. Capacity values are typical ranges, not a substitute for a specific battery's datasheet.

Applications

Commercial
Marine
Diesel

Technology variants

Heavy-duty flooded — see the lead-acid type family for the design trade-offs behind the label.

Equivalent capacity class

~200+ Ah — other groups in a similar capacity class. This is a capacity comparison, not a physical interchange: dimensions and terminals differ between naming families.

Testing

Relevant methods for this group: CCA testing, capacity testing, load testing — see the testing methods for procedures and standards.
