Energizer Max AAA Batteries (LR03) - 8 Pack

This is a card of eight Energizer Max AAA cells, supplied as a four plus four bonus pack. AAA is the slim 1.5V cylindrical cell that sits below AA in the everyday household sizes, and Max is Energizer's general purpose alkaline line. Every cell on the card is the same; the bonus format simply means you receive eight where a standard card of this kind holds four. The retail pack prints a 10 year shelf life, so a card put away in a drawer or a maintenance box is not a wasted purchase.

AAA suits the devices that sip rather than gulp: television and set top box remotes, wireless mice and keyboards, wall clocks, digital thermometers, kitchen scales, door chimes, small head torches and the lighter children's toys. Alkaline is the everyday chemistry for that pattern of intermittent, moderate drain use, and it is what most household kit is specified around when the label reads 2 x AAA. If you are restocking a whole house, count the remotes first, because most homes turn out to hold more AAA devices than AA ones.

There is nothing to set up. Check the plus and minus markings moulded into the battery compartment, fit the cells the way the moulding shows, and change a device's cells as a complete set rather than putting one fresh cell in beside a tired one. Each unit of this listing is a card of eight, and the minimum order is 12 cards sold in multiples of 12, which makes it a sensible line for a shop counter, an office stationery cupboard or a holiday let. It sits alongside our wider Energizer battery range, which runs from AA and AAA through C, D and 9V to lithium and silver oxide coin cells.

How many batteries do I actually receive?

Eight cells on a single card. The pack is printed as four plus four bonus, which is the same eight cells presented as a promotional format rather than two separate packs.

Will these work in a device that asks for LR03 or Micro cells?

Yes. LR03 is the international code for an AAA alkaline cell and Micro is the older German term for the same size, so all three names describe this battery.

What voltage does each cell give?

Each cell is 1.5V, so a device taking two AAA cells in series runs at 3V and one taking four runs at 6V. Check the compartment markings before fitting.

Can these be recharged?

No. Alkaline cells are single use by design and should not be put in a charger. Rechargeable AAA cells are a different chemistry, usually marked NiMH and rated at 1.2V.

How long will a set last in my remote or clock?

The manufacturer does not state a runtime for this pack, and it varies enormously with how hard the device pulls current. A clock may run for a year where a wireless mouse runs for weeks.

Should I mix these with the cells already in a device?

Better not to. Replace all the cells in a compartment at the same time and keep the same size and chemistry throughout, so one older cell is not being worked harder than the rest.
