Energizer Alkaline Power AAA Batteries (LR03) - 20 Pack

A maxi pack of twenty Energizer Alkaline Power AAA cells, each one a standard 1.5V alkaline battery in the LR03 size. Alkaline is the everyday chemistry: it holds a fairly steady voltage through most of its working life and then tails off, and it is the type almost every household battery compartment is designed around. The retail pack prints a seven year shelf life, and also notes that the cells include recycled materials. Twenty cells is a household quantity rather than a drawer top-up.

AAA is the size hiding in the things you only think about when they stop working: television remotes, wireless mice and keyboards, wall clocks, doorbell push units, kitchen scales, head torches, children's toys and small LED book lights. Those are mostly low and moderate drain jobs, which is exactly where alkaline cells make the most sense. A pack of twenty lets you keep a few in a kitchen drawer, a few in a toolbox and a few beside the remotes, so a clock that goes quiet on a Sunday evening is not a trip to the shops.

Two practical points worth knowing. Change every cell in a device at the same time and keep to one brand and chemistry throughout: a tired cell sitting beside a fresh one drags the whole set down, and that is the usual reason a device goes flat again within days. Store spares somewhere cool and dry, left in their card, with the terminals clear of loose coins and keys. These are primary cells, so they are used once and then taken to a battery recycling point rather than charged. This listing is one pack of twenty with a minimum order of one, and it sits alongside our wider range of Energizer Alkaline Power cells in AA, C, D and 9V.

Which devices usually take AAA cells?

Remote controls, wireless mice and keyboards, wall clocks, kitchen scales, head torches, children's toys and small LED lights are the common ones.

How many batteries do I actually receive?

Twenty cells in a single retail pack. The listing is sold as one pack of twenty, and the minimum order is one pack.

Are these the same as LR03 batteries?

Yes. LR03 is the international code for an alkaline AAA cell, so a device asking for LR03 takes these with no adapter.

What does the seven year shelf life on the pack mean?

It is the figure the manufacturer prints for unused cells left in their packaging and kept in normal cool, dry household storage.

Can I mix these with the older cells already in a device?

Better not to. Replace the whole set at once and keep to one brand and chemistry, because the weakest cell limits the rest.

Can these be recharged?

No. Alkaline cells are primary batteries, made to be used once and then taken to a battery recycling point rather than charged.
