Energizer Alkaline Power AAA Batteries (LR03) - 8 Pack

These are Energizer's Alkaline Power cells in AAA, the slim size that sits below AA in most household kit, supplied eight to a pack. Alkaline chemistry gives a nominal 1.5 volts per cell, which is the figure almost every AAA powered device is designed around, and it is the standard general purpose chemistry rather than a rechargeable one. The international code for an alkaline AAA is LR03, so if the old cell in your hand is marked LR03, or simply AAA, these are the same format. The pack prints a seven year shelf life and a claim of up to 50% longer lasting, measured against the IEC 2021 minimum average duration in portable lighting devices.

AAA is the size that quietly runs a house. Television and set top box remotes, wall clocks, computer mice and keyboards, wireless doorbells, kitchen scales, digital thermometers, head torches, children's toys and games controllers all take it, and most of those take two or four at a time. Eight cells therefore covers two or four devices in one go, or keeps a spare set in the drawer for the remote that always dies on a Sunday evening. Where a device holds more than one cell, change them all together and keep to one brand and chemistry in a compartment.

Buy them as a pack of eight; the minimum order on this listing is 12 packs, sold in multiples of 12, so it suits a workplace, a holiday let or anyone stocking a cupboard rather than replacing one remote. The seven year shelf life printed on the pack means cells bought in bulk are still worth putting in a device years later, provided they are kept in their packaging at normal room temperature. We stock the same Alkaline Power range in AA, C, D and 9V, so one order can cover every size a building uses.

My device manual says LR03 or micro. Is that the same as AAA?

Yes. LR03 is the international code for an alkaline AAA cell, and micro is the older European name for the same slim size, so all three refer to this battery.

How many cells do I actually receive?

One unit of this listing is a retail pack holding eight AAA cells. The minimum order is 12 packs in multiples of 12, so a first order brings 96 cells in total.

Can these be recharged in a charger?

No. These are single use alkaline cells rather than rechargeable NiMH, so once they are flat they should be taken out and recycled at a battery collection point.

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

It is the period the pack states unused cells will hold their charge in storage, which is why buying eight at a time makes sense even if you only need two now.

Will they run a high drain device such as a games controller or a head torch?

Yes, alkaline cells suit both steady drain items like clocks and remotes and heavier drain ones like torches, though a high drain device will always empty a cell faster.

Can I mix these with the cells already in my device?

Better not to. Replace every cell in a compartment at the same time and keep them to one brand and chemistry, as a part used cell drags the fresh ones down.
