Brand/label difference, not a size difference
AG13 vs A76
Both are alkaline LR44-size cells. AG13 is a generic/AG retail label; A76 is Energizer’s equivalent name. Duracell often uses 76A.

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.
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.
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.

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.
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.
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.
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.
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.
Both refer to the LR44 alkaline size family; branding differs (Energizer vs Duracell naming conventions).
Yes. AG13 vs A76 and A76 vs AG13 are the same pair. Fit, voltage, and chemistry do not change when you flip the order.
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.
