What is the Difference Between H7 and 94R Batteries? — H7 vs 94R Explained
There’s no actual difference between an H7 and a 94R battery, they are the same physical group size, just named differently depending on whether you follow the European (EN) or North American (BCI) standard.
Understanding Battery Group Codes
Car batteries come in standardized “group sizes” that define maximum dimensions, terminal orientation, and mounting style.
-
In Europe, the H-series (H5, H6, H7, H8) designations are common.
-
In North America, the BCI Group numbers (47, 48, 94R, etc.) are used.
So, H7 and 94R describe the same physical footprint, they’re simply different names under different standards.
H7 vs 94R: The Real Difference
| Feature | H7 | 94R | Comment |
|---|---|---|---|
| Naming Standard | European (EN) | North American (BCI) | Different systems, same size |
| Dimensions (L×W×H) | 315 × 175 × 190 mm | 12.375 × 6.875 × 7.5 in | Identical footprint |
| Terminal Orientation | Positive on Right | Positive on Right (“R”) | Same layout |
| Common Chemistry | AGM / Flooded | AGM / Flooded | Varies by model |
| Common Equivalent Codes | L4, LN4 | — | Same family |
| Interchangeable? | Yes | Yes | 100% interchangeable |
In other words, H7 = 94R. There’s no size or polarity difference — only a naming difference between European and American standards.

FAQ: Common Questions about H7 and 94R
Q1. Is there any real difference between H7 and 94R batteries?
A: No. They’re the same group size: H7 (EN standard) and 94R (BCI standard) describe identical dimensions and layout.
Q2. Can I replace a 94R with an H7?
A: Yes. They’re 100% interchangeable. They belong to the same battery.
Q3. What does the “R” in 94R mean?
A: “R” stands for “Right-hand positive terminal.” It helps distinguish terminal orientation from other similar groups.
Q4. Are all H7/94R batteries AGM?
A: Not necessarily. You can find both AGM and flooded lead-acid versions in this size. Check your vehicle requirements. Generally speaking, AGM batteries can replace conventional flooded lead-acid batteries. And AGM battery have longer lifespan time than flooded lead-acid batteries
Q5. What are the equivalent codes for H7/94R?
A: Other regional equivalents include L4, LN4, or DIN 77L4 — all referencing the same physical dimensions.
