Group 27F Battery

Aliases: 27F · Standard family: BCI/SAE

Direct answer: The Group 27F battery is a BCI/SAE-family group — a 12V lead-acid case of 318 × 173 × 227 mm with SAE post (front) terminals, typically 90–100 Ah and 710–800 cold cranking amps (SAE J537 (−18°C)).

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

Ford trucks
Large SUVs
Light commercial

Technology variants

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

Equivalent capacity class

~90–100 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.
