Description
The MN27 is a 12V alkaline cell, and this listing is a single cell on its own blister card. Duracell prints four further codes for the same battery on the front of the pack: A27, 27A, V27A and 8LR732, so if any one of those is marked on the cell you are replacing, this is the one you want. It is a specialist size rather than a household one, which is why it is easy to be caught out when the old one runs down.
Cells of this size and voltage do a particular job: they sit in small handheld transmitters where a 1.5V cell does not give enough voltage and a larger battery will not fit. Car keyless entry fobs, garage and gate remotes, alarm fobs, doorbell push units and camera remote releases are the usual homes for a 12V cell of this shape. The safest way to buy is to open the old unit, read the code stamped on the side of the spent cell and match it, rather than going by the device brand.
Each unit here is one cell, and the minimum order is ten units sold in multiples of ten, so a single order brings ten cells: useful if you look after several vehicles, gates or alarm fobs, or simply want spares put by. The retail pack carries a keep out of reach of children warning, which is worth heeding with a cell this small. Alkaline is the standard chemistry for this size, and cells of this type are not built to be recharged, so a spent one goes to battery recycling rather than onto a charger. It sits alongside our wider Duracell range, which runs from lithium coin cells and silver oxide watch cells to hearing aid cells and AA packs.

Frequently Asked
Is MN27 the same battery as A27 or 27A?
Yes. The pack prints A27, 27A, V27A and 8LR732 as codes for this same cell, so a device marked with any of those takes it.
How many cells do I actually receive?
One cell per unit, on its own blister card. The minimum order is ten units, so a single order brings you ten individual cells.
How do I check this is right for my key fob?
Open the fob and read the code along the side of the old cell. If it reads MN27, A27, 27A, V27A or 8LR732, this matches.
What voltage does it give?
12V, which is what small radio transmitters such as key fobs and gate remotes need. A 1.5V AA or AAA cell is not a substitute.
Can this cell be recharged?
No. Alkaline cells of this type are primary cells, made to be used once, so a charger will not bring a flat one back.
Does the manufacturer state a shelf life?
No shelf life figure is printed on this retail pack. The wording on the front reads long lasting power guaranteed and gives no dated figure.
