Description
This is JCB's LR44 alkaline coin cell, supplied on a card of ten. The card names the cell twice, as LR44 and as AG13, and gives the voltage as 1.5V. Alkaline is the standard chemistry for button cells of this size and it is what most devices calling for an LR44 are built around. The ten cells sit in separate blisters along the card, so you can press one out when you need it and leave the other nine sealed.
LR44 is one of the button cell sizes you meet most often around the house. Kitchen scales, digital thermometers, laser pointers, pocket calculators, car key fobs, glucose meters, light-up toys and small LED torches all commonly take one, and plenty of devices stack two or three of them in a short tube to make 3V or 4.5V. That is worth knowing before you order, because a device that takes three cells empties a card of ten faster than you expect. If you are replacing cells in something that uses more than one, change the whole set together rather than mixing an old cell with a new one.
AG13 on the card is the same cell under a different naming system, so a manual asking for AG13 takes this one. Where a manual specifically calls for SR44, that is the silver oxide version of the same size, a different chemistry in the same shell, and worth checking before you buy. The card carries a printed warning to keep batteries away from children, which is the sensible way to treat a cell this small. We sell this listing as a single card of ten cells, with a minimum order of ten cards in multiples of ten, which suits a spares drawer or a workshop rather than a one-off replacement. We also stock JCB cells in AA, AAA, 9V and lithium coin sizes.

Frequently Asked
Is AG13 the same battery as LR44?
Yes. They are two naming systems for the same 1.5V alkaline button cell, and this card prints both codes.
How many cells do I actually receive?
One card holding ten cells. The minimum order on this listing is ten cards, sold in multiples of ten cards.
My device manual asks for SR44. Can I use this instead?
SR44 is the silver oxide cell of the same size rather than an alkaline one, so follow whichever chemistry your manual specifies.
What voltage does each cell give?
Each cell is 1.5V, as printed on the card. Devices holding two or three in series run at 3V or 4.5V.
Can these cells be recharged?
No. These are single use alkaline cells and should never be put in a charger. Use a rechargeable cell where your device calls for one.
