Description
This is Energizer's A23, an alkaline cell that gives 12V from a single small cylindrical body, and it arrives two cells to a pack. The 12V figure is the thing to notice: most household cells give 1.5V, so a device that asks for an A23 is asking for something specific rather than a substitute AA. Alkaline is the chemistry, which means a primary cell you fit once and replace when it runs down rather than one you put back on charge. The pack states 12V alkaline batteries and carries two cells behind the window.
A23 cells turn up in the small, low drain electronics that need a high voltage from very little room: car key fobs, alarm remotes and sensors, garage and gate openers, wireless doorbells and blind or fan handsets. If the old cell is out and you are not sure what it was, read the print along its side, where the size code is usually marked plainly. Two cells to a pack suits a household with one fob in use and one spare in a drawer, and it suits a van or a workshop where the same handset keeps coming back.
There is nothing to set or switch on a cell like this: fit it the right way round, matching the plus and minus marks in the compartment, and the device does the rest. One unit of this listing is a pack of two cells, and the minimum order is 10 units in multiples of 10, so the smallest purchase brings 20 cells. That suits a maintenance cupboard or a counter more than a single replacement. If you need one cell only, the same Energizer A23 alkaline is listed here as a single, and we stock Energizer alkaline AA, AAA, C, D and 9V cells as well.

Frequently Asked
Which devices use an A23 battery?
Small, low drain electronics that need 12V in very little room: car key fobs, alarm remotes and sensors, gate and garage openers, wireless doorbells and blind or fan handsets.
Is an E23A the same cell?
Yes. This cell is listed under more than one code name, E23A among them, so a device that asks for either one takes it.
Are these rechargeable?
No. Alkaline cells are primary cells, fitted once and replaced when they run down, so nothing here goes back on charge.
How many cells do I get, and what is the smallest order?
Each pack holds two cells. The minimum order is 10 packs, in multiples of 10, which brings 20 cells in total.
Will an A23 replace a 9V PP3 or a AA?
No. The voltage and the body differ in each case, so fit only the size the device's compartment calls for, which is an A23 here.
