Standards & measurement context

Naming standardJIS
CCA basisJIS D5301 (−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

Technology variants

Flooded MF — see the lead-acid type family for the design trade-offs behind the label.

Equivalent capacity class

~85–95 Ah — other groups in a similar capacity class. This is a capacity comparison, not a physical interchange: dimensions and terminals differ between naming families.
