Energizer Alkaline Power AAA Batteries (LR03) - 24 Pack

This is a maxi pack of twenty-four Energizer AAA cells from the Alkaline Power range, supplied as one sealed box. Each one is a standard 1.5V alkaline AAA carrying the international code LR03, so it suits anything asking for AAA, LR03 or R03. Alkaline is the everyday household chemistry, striking a workable balance between capacity and cost in devices that draw a steady, modest current rather than a heavy one. The retail pack prints a seven year shelf life, which is what makes buying two dozen at once sensible rather than wasteful.

AAA is the slimmer of the two sizes most homes get through, and it tends to live in the things nobody thinks about until they stop working: television and set top box remotes, wall clocks, wireless keyboards and mice, kitchen scales, head torches, door chimes, children's toys and games controllers. If you are unsure which size a device takes, the quick check is width rather than length. Under the IEC standard an AAA is about 10.5mm across, where an AA is nearer 14.5mm, and both sit at a similar sort of length. A cell that feels noticeably fatter in the hand is an AA, and this pack is the wrong one for it.

Alkaline cells are primary cells: they are made to be used once and are not rechargeable, so a flat one is simply replaced. One unit of this listing is the box of twenty-four, and the minimum order is eight boxes in multiples of eight, so the smallest order brings 192 cells in. That suits an office, a school, a holiday let or a household that would rather not think about AAA again for a while. We stock the same Alkaline Power range in AA, C, D and 9V if you need other sizes on the same order.

Will these work in anything marked LR03 or R03?

Yes. AAA, LR03 and R03 are three names for the same cell size, so a device printed with any of those codes takes these.

How do I tell an AAA from an AA before I order?

Compare the width rather than the length. Under the IEC standard an AAA is about 10.5mm across and an AA nearer 14.5mm, so the AA is visibly the fatter cell.

Can these be recharged?

No. Alkaline cells are primary cells, made for single use, so once the voltage falls away they are replaced rather than topped up in a charger.

How long will the pack keep before I need to use it?

The retail pack prints a seven year shelf life, so a box bought now can sit in a drawer and still be worth opening a good while later.

How many cells do I actually receive?

One unit of this listing is a box of twenty-four cells. The minimum order is eight boxes in multiples of eight, which works out at 192 cells.

What sort of devices do alkaline AAA cells suit best?

Steady, modest drain equipment suits alkaline well: remote controls, wall clocks, wireless keyboards and mice, kitchen scales, door chimes and children's toys.
