In the U.S. market, 94R and H7 label the same 12-volt battery size class, but CCA, amp-hours, and chemistry still vary by model.
For the full breakdown, see our best 94R H7 Battery guide.
H7 is the European DIN label and 94R the North American BCI group number for the same physical case; a listing reading “94R/H7” names one size twice. The mistake is assuming a shared label means shared output — a battery that drops right in can still crank weaker than the one it replaced.
Is 94R the Same as H7?
Yes — 94R and H7 are interchangeable size labels for the same 12V form factor. H7 is also sold as L4, and occasionally as “94R/H7,” all pointing at the same case dimensions.
The letters carry separate information. “R” in 94R marks terminal polarity: positive on the right facing the battery’s front, which matches H7 listings for this class. What they don’t standardize is anything under the lid.
94R and H7 Specs Compared
Size is fixed; performance isn’t. CCA, reserve capacity, and amp-hours shift by model even under the same 94R or H7 label.
| Model | Key Specs | Type |
|---|---|---|
| Interstate MTP-94R/H7 | 790 CCA, 985 CA, 130 min RC, 42.9 lb | Flooded (wet) |
| Interstate MTP-94R/H7-1 | 800 CCA, 985 CA, 130 min RC, 80 Ah | Flooded (wet) |
| Exide 94R/H7 listing | 880 CCA at 0°F, 1090 CA at 32°F, 90 Ah, 180 min RC | Flooded (wet) |
| Retail AGM listing | 850 CCA, 140 min RC, 80 Ah | AGM |
| Shared case size | 12 3/8 × 6 7/8 × 7 1/2 in | All above |
Read that table vertically. The bottom row is the only constant — roughly 12.4 in long, 6.9 wide, 7.5 tall. Everything above is a model choice.
What Actually Decides Fit
Four things: length, width, height, terminal orientation. The label gets you close, but a tape measure closes the deal, since aftermarket listings sometimes stretch a name across different cases.
Chemistry is the skipped part. Many vehicles that accept this size call for AGM rather than flooded — often start-stop systems. Both exist in 94R/H7, so the right size says nothing about the right type.
Don’t treat every H7 as equal in output: two batteries can share the exact case and differ by 90 CCA. Match CCA to what your engine asks for. For side-by-side comparisons, the tested picks for this size class are a good starting point.
BCI group numbers and DIN codes run in parallel, and this class is where sellers mix them. “Group Size 94R” and “H7” on one spec sheet isn’t an error; “L4” is the same again.
Exide’s spec sheet for its 94R / H7 flooded battery shows the pattern: one size label, its own cranking and reserve numbers.
What To Check Before Buying
Match the battery to the car, not the label — the label only says the case will probably sit in the tray.
- Measure the old battery’s length, width, height, or read its group size.
- Confirm terminal polarity — positive on the right facing the front.
- Check the manual for required chemistry: flooded or AGM.
- Match CCA to the vehicle’s spec, especially in cold climates.
- Buy the amp-hours and reserve capacity your accessories draw.
It was never two batteries — one size with several batteries wearing its name, and the spec sheet numbers are what you’re choosing between.
FAQs
Can I swap an H7 battery for a 94R?
If case dimensions and terminal orientation match, yes — same size class. Verify length, width, height, and positive-post side, then check chemistry and CCA meet your vehicle’s requirement, since the size label doesn’t fix those.
Is 94R the same as L4?
L4 is another alternate name for this same H7 / 94R class. You may see H7, L4, and 94R on one box — the same 12-volt case, not three batteries. Performance ratings still vary by model.
Do all 94R batteries have the same power?
No. CCA, reserve capacity, and amp-hours differ between models even with a matching label. Interstate’s MTP-94R/H7 lists 790 CCA; an Exide listing for the same size shows 880 CCA. Match the rating to your engine’s spec.
