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.
Last reviewed
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.
The other manufacturer codes
Duracell prints 76A, Varta prints V13GA, Renata and others use their own numbers. All of them describe the same 11.6 × 5.4 mm alkaline cell. Counting how many codes one battery carries is a decent illustration of why a cross-reference index is useful at all.
Why manuals use the manufacturer number
A device maker writes the manual around whichever supplier it contracted with, so the code printed there is often a brand part number rather than the IEC name. That is why a manual can ask for something the local shop has never heard of while stocking the identical cell under another label.
Buying on price
Since the codes describe one cell, there is nothing to weigh but price, freshness and whether you trust the brand not to leak. Check the date on the pack — alkaline button cells lose capacity slowly on the shelf, and bargain multipacks are sometimes bargains because they are old.
Can I use an A76 instead of an 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.
LR44 vs A76: common questions
Is the A76 a direct replacement for the LR44?
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.
What is the difference between the LR44 and the 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. In short: the same cell — A76 is Energizer's code for the LR44.
Are the LR44 and the A76 the same size?
Yes. Both measure 11.6 × 5.4 mm, so either fits where the other does. Whether they are interchangeable is an electrical question, not a physical one.
