Description
This is the LR44 alkaline button cell, supplied four to a card. LR44 is a standard IEC size, so a cell bought under that code is the same physical cell whatever name appears on the card, and it is also catalogued as AG13. The chemistry is alkaline, which gives the 1.5V nominal output that small electronics are built around. The four cells are held in a blister at the centre of the card, so you can take one out and leave the other three sealed until they are wanted.
LR44 is the cell that turns up in the small things around a house rather than in anything large. Kitchen scales, calculators, laser pointers, digital thermometers, key fobs, small LED torches and a great many children's toys and novelty lights all run on one, two or three of them stacked in a tube. Because a single cell costs little and a flat one stops the device outright, most people want more than one to hand: four on a card covers a set of scales and a thermometer with spares left over.
Each unit you buy is one card of four cells. The minimum order on this listing is 10 cards, so the smallest purchase brings 40 cells in total, which suits a workshop, a school or anyone restocking a spares drawer rather than replacing a single battery. Alkaline cells of this type are primary cells and are not made to be recharged; when one is flat it is replaced. This cell sits within our wider range of JCB batteries, which runs from AAA and AA up through 9V and D, and takes in lithium coin cells such as CR2016, CR2025 and CR2032.

Frequently Asked
What other codes is an LR44 sold under?
It is the same cell as an AG13, and we list both codes so you can match whichever name is printed inside your device.
What sort of devices take LR44 cells?
Kitchen scales, calculators, laser pointers, digital thermometers, key fobs, small torches, toys and novelty lights are the usual ones, often taking two or three stacked together.
How many cells do I get, and what is the smallest order?
One unit is a card of four cells, and the minimum order is 10 cards, so the smallest purchase brings 40 cells.
What voltage does one of these give?
Alkaline chemistry gives 1.5V nominal per cell, which is what devices designed around the LR44 size expect from a fresh battery.
Can these be recharged?
No. These are alkaline primary cells, intended to be used once and then replaced rather than put on a charger.
