| Standard family | BCI/SAE |
| Voltage | 12V |
|---|---|
| Typical capacity | 55–75 Ah |
| Typical CCA | 750–900 A |
| Dimensions (L×W×H) | 260 × 173 × 200 mm |

| 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.
Flooded / AGM — see the lead-acid type family for the design trade-offs behind the label.
~55–65 Ah — other groups in a similar capacity class. This is a capacity comparison, not a physical interchange: dimensions and terminals differ between naming families.
Relevant methods for this group: CCA testing, capacity testing, load testing — see the testing methods for procedures and standards.
CCA 750–900 A — SAE J537 (−18°C)

Same case as Group 34 but with REVERSED terminal polarity (positive post on the opposite side). Dimensions match Group 34; the 'R' suffix denotes reversal, not a size difference. Not interchangeable with Group 34 without checking cable routing.
