AG13 vs A76: Same Alkaline Cell, Different Labels
Both are alkaline LR44-size cells. AG13 is a generic/AG retail label; A76 is Energizer’s equivalent name. Duracell often uses 76A.

Are AG13 and A76 interchangeable?
Interchangeable alkaline replacements.
Shop by a fresh name-brand pack of the same outline. The retail prefix (DL, ECR, AG, A76) is usually a label, not a new size. Confirm voltage and chemistry before you treat any “almost the same” listing as a drop-in.
AG13 vs A76 specs
They share 1.5 V and Alkaline and 11.6 mm diameter, which is why AG13 vs A76 looks interchangeable on a store shelf. Highlighted rows, if any, are the shopping differences. Matching rows are why the two names get searched together.
Read physical fit before capacity. Extra milliamp-hours only help when the holder is built for that cell. A “better” spec in the wrong tray is a mechanical or voltage mismatch, not an upgrade.
Difference between AG13 and A76 batteries
If you searched A76 vs AG13, you are on the same comparison with the names reversed. The difference between AG13 and A76 batteries is not the word “vs” — it is the specs that do not match after you ignore the similar photos.

How the size code works (AG13 vs A76)
Coin and button codes are rulers, not brand slogans. The letters mark chemistry class. The digits encode size. AG13 measures 11.6 × 5.4 mm; A76 measures 11.6 × 5.4 mm. Once you read the code that way, A76 vs AG13 stops looking like a preference and starts looking like a fit check.
Can I use a AG13 instead of a A76?
Usually yes. AG13 and A76 belong in the same holder class when voltage, chemistry, and outline match. Use a fresh name-brand pack.
If the spent cell said A76, AG13 is the correct replacement only when the spec table shows the same size and voltage. A similar prefix (LIR, ML, BR, 14500) is not this swap.
Can I use a A76 instead of a AG13?
Usually yes — it is the same pair in the other order. A76 vs AG13 does not change fit or voltage.
Buy the fresher authentic pack. Counterfeit retail wrappers are a bigger risk than the extra letter on the can.
How to identify AG13 versus A76
You do not need a full datasheet to settle AG13 vs A76. You need the stamp, the tray, or a cheap pair of calipers. A store bin labeled only “button cell” or “3V lithium” will not do that work for you.
- Read the code on the old cell: AG13, A76, and the brand prefixes that map to each one.
- If the print is worn off, check the tray, battery door, or user manual before buying.
- Measure diameter if the codes are gone: AG13 is 11.6 mm; A76 is 11.6 mm.
- Measure thickness: AG13 is 5.4 mm; A76 is 5.4 mm.
- Buy the matching code. Extra capacity or a thicker can only helps when the holder is built for that cell.
Choose AG13 when…
- Shopping cart or tray says AG13
Choose A76 when…
- You prefer Energizer A76 packaging
Compatibility and substitution
Treat AG13, A76, 76A, and LR44 alkaline packs as the same shopping target.
Do not stack cells, grind a can, or use foil as a permanent spacer to fake A76 with AG13. Read the stamp, then the spec table. If the door will not close without force, you have the wrong height or diameter.
AG13 vs A76 FAQ
A76 vs 76A?
Both refer to the LR44 alkaline size family; branding differs (Energizer vs Duracell naming conventions).
I searched A76 vs AG13 — is this the right page?
Yes. AG13 vs A76 and A76 vs AG13 are the same pair. Fit, voltage, and chemistry do not change when you flip the order.
Should I always trust a cross-reference chart?
Use this guide as a starting point, then confirm voltage, chemistry, and physical size with your device manual or the marking on the old cell.
