LR44 vs A76
A76 is Energizer's part number for the alkaline LR44: the same 11.6 × 5.4 mm cell at 1.5 V and 110–130 mAh.
Same battery, different label. LR44 is the international standard code; A76 is the part number Energizer prints on its version. Same alkaline chemistry, same 1.5 volts, same 11.6 × 5.4 mm cell, same 110–130 mAh. Anything that takes one takes the other, and there is no quality difference implied by either code — only which brand is on the packet. If a manual asks for an A76 and the shop has LR44, buy it.
- Verdict:
- The same cell — A76 is Energizer's code for the LR44
- Interchangeable:
- yes — the same cell under two codes

Size comparison
Both cells share an identical 11.6 × 5.4 mm footprint, so physical fit is not the deciding factor here.
A manufacturer code, not a spec
A76 identifies the product in Energizer's catalogue. Duracell sells the same cell as 76A, Varta as V13GA. None of these describe a different battery.
Same figures throughout
1.5 V, 11.6 × 5.4 mm, 110–130 mAh. There is no performance decision to make between the two codes — only a price and availability one.
Where the confusion starts
Device manuals tend to quote whichever code the manufacturer's battery supplier used, so a manual asking for an A76 and a shelf stocked with LR44 is the normal case, not a mismatch.
Can I use a A76 instead of a LR44?
Yes. The LR44 and the A76 are the same cell — 11.6 × 5.4 mm, 1.5 V, alkaline. The two codes come from different naming schemes, not from different batteries, so whichever you find on the shelf will work.
Check before you swap. Batteries with similar dimensions are not always interchangeable. Always verify voltage, chemistry and the requirements printed in your device manual before fitting a replacement.
