Group 27 Battery

Aliases: 27 · Standard family: BCI/SAE

Direct answer: The Group 27 battery is a BCI/SAE-family group — a 12V lead-acid case of 306 × 173 × 225 mm with SAE post terminals, typically 90–95 Ah and 800 cold cranking amps (SAE J537 (−18°C)).

Value types — Standard-defined: fixed by the group standard (voltage, dimensions, terminal); Manufacturer-reported: a representative value from manufacturer datasheets; World Battery Hub derived: a cross-source range aggregated by World Battery Hub from manufacturer datasheets. None is a substitute for a specific battery's datasheet.

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

Marine
RV
Trucks

Technology variants

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

Equivalent capacity class

~90–95 Ah — other groups in a similar capacity class. This is a capacity comparison, not a physical interchange: dimensions and terminals differ between naming families.

Testing

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