Energizer Alkaline Power AAA Batteries (LR03) - 12 Pack

This is a maxi pack of twelve AAA alkaline cells from Energizer's Alkaline Power line. AAA is the slim penlight size, listed under the IEC code LR03, and every cell here gives the standard 1.5 volts that small electronics are built around. Alkaline chemistry is the everyday workhorse of the battery drawer: it holds a steady voltage under light and moderate loads, sits patiently between uses, and costs far less per cell than lithium. Twelve cells arrive on one hanging card, so a household refill is a single purchase rather than a rolling series of two packs.

AAA is the size that fills the small things: television and set top box remotes, wall clocks, computer mice and wireless keyboards, kitchen scales, digital thermometers, head torches, doorbell pushes and most of the noisier children's toys. If you are not sure which size a device takes, open the compartment and check before you buy. AAA is noticeably slimmer and shorter than AA, so an AAA cell will rattle loose in an AA holder and will not bridge the contacts properly. Offices, classrooms and holiday lets tend to get through AAA faster than any other size, which is exactly what a twelve pack is for.

The retail pack prints a 7 year shelf life, so spares bought now are still useful several winters from now, provided they are kept dry and at room temperature rather than in a cold shed. These are single use cells and are not designed to be recharged. One unit of this listing is one pack of twelve cells, and the minimum order is twelve packs, sold in multiples of twelve, which suits a stockroom rather than a single kitchen drawer. Alkaline Power also runs to AA, C, D and 9V with us, so one chemistry can cover the whole house. Please take spent cells to a battery collection point.

Which devices usually take AAA cells?

Remotes, wall clocks, computer mice, wireless keyboards, kitchen scales, digital thermometers, head torches and a great many children's toys all run on AAA.

Is LR03 the same thing as AAA?

Yes. LR03 is the IEC code for an alkaline AAA cell, so a device asking for LR03 or for AAA takes exactly this cell.

Can I use an AAA cell where the device asks for AA?

No. AAA is shorter and slimmer, so it will sit loose in an AA holder and fail to make contact. Check the compartment before ordering.

Are these rechargeable?

No, these are single use alkaline cells. If you want cells you can put back on charge, look for a rechargeable NiMH AAA instead.

How many cells do I actually receive?

One unit is a pack of twelve cells. The minimum order is twelve of those packs in multiples of twelve, so 144 cells in total.
