Energizer Alkaline Power AA Batteries (LR6) - 20 Pack

These are Energizer Alkaline Power AA cells, supplied 20 to a pack. Each cell is a standard 1.5V alkaline AA, carrying the IEC code LR6, so it is the same size and voltage as the AA you are replacing, whatever brand went in before. Alkaline is the everyday chemistry: it is not rechargeable, it holds its charge well on the shelf, and the pack prints a seven year shelf life. Twenty cells is a household quantity rather than a top up, which suits the drawer everything gets raided from.

AA is the cell most homes get through fastest. Remote controls, wireless keyboards and mice, wall clocks, children's toys, kitchen scales, digital thermometers and most torches take it, and a good many of those take two or four at a time, which is why a single blister of four rarely lasts long. Alkaline suits anything that draws modestly and steadily. Where a device gets through cells weekly, a rechargeable is usually the better answer; where it sits quietly for a year between changes, alkaline is the sensible choice and costs less to keep in the cupboard.

Always change a full set together and match chemistries rather than mixing an old cell with a new one; devices running several cells in series are held back by the weakest. Keep the unopened pack somewhere cool and dry, and take spent cells to a recycling point rather than the bin. This listing is one pack of twenty, with a minimum order of one, so a single pack is fine to buy. We stock other Energizer alkaline sizes alongside it, including AAA in a twenty pack, C and D in two packs, and a 9V.

How many batteries do I actually receive?

Twenty cells in one pack. That is the whole purchase, so one order fills a remote, a couple of toys and a torch with cells left over.

Is LR6 the same thing as AA?

Yes. LR6 is the IEC code for a 1.5V alkaline cell in the AA size, so a device asking for either will take these.

Can these be recharged?

No. Alkaline cells are single use and should not be put in a charger. If you want to recharge, you need cells sold as rechargeable NiMH.

How long can I keep them before use?

The pack states a seven year shelf life. Store the unopened pack somewhere cool and dry rather than on a sunny windowsill or near a radiator.

Can I put one of these in alongside a part used cell?

It is better not to. In a device holding two or more cells, the weakest one limits the set, so change them all together.

What voltage does each cell give?

Each cell is nominally 1.5V, the standard for alkaline AA, so four in series give a nominal 6V as most battery compartments expect.
