1.5 V · 11.6 × 5.4 mm · Alkaline manganese button
AG13 is a label on Energizer's A76 product page, in the 'replacement for' line next to LR44. A76 is the alkaline 11.6 × 5.4 mm cell, IEC-LR44, nominal 1.5 V. AG13 is not given its own milliamp-hour rating on that page. The numbers below are the A76 datasheet and Renata's LR44 line. SG13, which looks similar, is on Energizer's cross-reference under the silver-oxide 357/303 line, not under A76.

Can I substitute it?
Same outline as 357 and 303 (11.6 × 5.4 mm) and as hearing-aid 675. LR44 is alkaline 1.5 V with a sloping curve. 357/303 are silver oxide at 1.55 V with a flat curve. 675 is zinc-air. Energizer's A76 page lists 357 and SR44 as labels A76 replaces, and Energizer's alkaline handbook says to make that swap only where the device manufacturer recommends it. If the meter or the watch says 357, fit 357. If it says LR44, AG13 or A76, the alkaline cell is the one that was specified. Never fit a CR2032 here.
Size check at real size
Lay the old cell on the outline. This shows the top outline (diameter) and the side outline (height) at 1:1 once the screen is calibrated.

Calibrate this screen
Screens scale pages differently, so true size is only true after calibration. Hold a bank card or ID card (85.60 mm wide, ISO/IEC 7810 ID-1) against the bar and slide until the bar is exactly as wide as the card.

Cross-reference
Each code is printed on the cited chart. A shared outline is not, by itself, the same cell. Renata's chart puts Maxell, Panasonic, Sony and Toshiba in one column, so those four names share the code shown.

|---|---|
| Energizer | A76 |
| Maxell, Panasonic, Sony, Toshiba | LR44 |
| Varta | V13GA |
| Rayovac | RW82 |
| Duracell | LR44 |
| Timex | KA |
| Citizen | 280-904 |
| Seiko | SB-F9 |
| IEC code on the Renata chart | LR1154 Printed as 'LR1154 (LR44)'. |
| IEC code on the Renata chart | LR44 Printed as 'LR1154 (LR44)'. |

Alkaline manganese button cells
An LR button is zinc/manganese dioxide with an alkaline electrolyte, nominal 1.5 V. Energizer's miniature alkaline handbook puts the open-circuit voltage near 1.6 V and then shows a sloping discharge, and it says the cathode swells as the cell empties. The cell is built to be the cheaper part. The handbook's own rule for using it in place of silver oxide is narrow: only where the device manufacturer recommends the substitution.
The size that dominates the search logs is LR44. Energizer sells it as A76, designation ANSI/NEDA 1166A, IEC-LR44. The current A76 datasheet rates 150 mAh to 0.9 V on 6.8 kΩ at 21°C. Renata's scope chart, July 2016, rates LR44 at 110 mAh and states the outline as 11.6 × 5.4 mm. Same code, two tests, two numbers. The Energizer A76 product page lists AG13 among the labels that A76 replaces, which is why a search for AG13 lands here. It also lists 357, SR44 and SG13. Those last three are silver-oxide designations for the same outline. Energizer is telling you the A76 will fit and run the device. The handbook is telling you it will not hold voltage the way 357 does. Both documents are Energizer's. Fit is not the same claim as service life.
LR41, LR43 and LR54 are the smaller alkaline outlines, Energizer numbers 192, 186 and 189. AG12 and AG10 show up on Energizer's cross-reference on the same lines as those alkaline cells and as the silver-oxide cells of the same diameter and height. An AG10 search is answered with the alkaline LR54 facts, and the silver-oxide neighbours are linked beside it, not folded into it.
