Description
The LR54 is a 1.5V alkaline button cell, and one pack holds two of them. Duracell prints the alternative codes on the front of the blister: 189, 191, V10GA and LR1130. If the cell you are replacing carries any one of those markings, this is the same cell under a different name. Coin cells are easy to order wrongly, and the code sprawl is why. Watch, meter and gadget makers each tend to quote whichever code their own cell supplier used, so a single physical cell can appear in four manuals under four numbers.
Cells this size turn up in quartz watches, digital thermometers, kitchen scales, calculators, laser pointers and medical meters. One point worth knowing before you buy: alkaline gives a nominal 1.5V that drifts gently downwards as the cell drains, while a silver oxide cell of the same physical size holds closer to 1.55V until it is nearly spent. Devices that only need to be powered are happy with alkaline; a watch movement or a precision meter is often specified for silver oxide instead. Check the old cell or the manual, and match the chemistry it names as well as the size.
One listing is one blister of two cells, and we sell these in multiples of ten, so the smallest order brings twenty cells. That suits a repair bench, a workshop or a counter more than a single swap. The pack carries Long Lasting, Power Guaranteed and no dated shelf life, so we quote none here. Loose button cells can short against coins and keys, so leave them blistered until they are wanted, and heed the pack's warning to keep them out of reach of children. Duracell coin and specialist cells sit alongside this one in our range, including LR44 alkaline, CR2032 and CR1620 lithium, and SR621 and SR626 silver oxide.

Frequently Asked
Is an LR54 the same cell as an LR1130?
Yes. The pack lists 189, 191, V10GA and LR1130 as codes for this same cell, so any device asking for one of those takes it.
How many cells do I actually receive?
Each pack holds two cells, and the minimum order is ten packs, so the smallest purchase brings twenty individual 1.5V cells.
What voltage does it give, and does that drop in use?
It is a nominal 1.5V alkaline cell. Alkaline voltage eases downwards gradually as the cell drains rather than holding flat to the end.
My device manual asks for a silver oxide cell of this size. Can I fit this one?
It will physically fit, but silver oxide holds a steadier 1.55V. Where a manual specifies silver oxide, fit silver oxide rather than alkaline.
