Description
This is a JCB LR41 alkaline coin cell, supplied ten to a card. LR41 is the standard code for the cell, and the same cell is also sold as AG3; the pack carries both markings, so whichever of the two is printed on the one you are replacing, this is the right size. The chemistry is alkaline, the everyday option at this diameter, and each cell is a small flat disc rather than the cylinder shape of an AA or AAA. The card holds ten, two abreast across five rows, each in its own pocket.
An LR41 is one of the more common button cells, so the reliable way to check is to read the code off the cell already in the device, or the marking moulded inside the battery compartment: it will give LR41, AG3, or another number for a cell of a different size. Ten on a card suits a household with several small devices to keep running, or a workshop drawer of spares. Keep the unused cells on the card rather than loose in a drawer, since a coin cell left loose can short against keys, coins or other cells.
A single alkaline cell runs at 1.5V nominal, whatever its size, though JCB prints neither a voltage nor a shelf life figure on this card, so we quote neither. The pack does carry a warning to keep batteries away from children, and it is worth heeding: a swallowed coin cell is a medical emergency, so keep spares out of reach and take used cells to a recycling point rather than the bin. The listing is sold as one card of ten cells, with a minimum order of ten cards. It sits alongside the wider JCB battery range we stock, which runs from AAA and AA through C, D and 9V, with other coin cells including LR44 and CR2032.

Frequently Asked
Is AG3 the same as LR41?
Yes. They are two naming systems for the same alkaline button cell, and this pack carries both codes, so either marking on your old cell points here.
How many cells do I get, and what is the minimum order?
One card holds ten cells. The listing is sold in multiples of ten cards, so the smallest order is ten cards of ten cells.
What voltage does an LR41 give?
A single alkaline cell is 1.5V nominal, whatever its size. JCB prints no voltage figure on this card, so treat 1.5V as the standard chemistry figure rather than a printed rating.
How do I check my device takes this cell?
Read the code on the cell you are taking out, or the marking inside the battery compartment. It should read LR41 or AG3 before you order.
What should I do with used cells?
Take them to a battery recycling point rather than putting them in household waste, and keep both new and spent coin cells away from children.
