Energizer Max AAA Batteries (LR03) - 5 Pack

This is a card of five AAA alkaline cells from the Energizer Max line, supplied as four cells plus one bonus cell on a single blister. AAA is the slim cylindrical size, narrower and shorter than an AA, and it carries the international code LR03. Every alkaline cell of this size gives a nominal 1.5 volts, which is what any battery compartment marked AAA is built around. The retail pack states a shelf life of ten years, so a card bought now can sit in a drawer as spares rather than going straight into use.

AAA is the cell that tends to run a house rather than power it: television and set top box remotes, wall thermostats and heating programmers, wireless doorbells, computer mice and keyboards, kitchen scales, wall clocks, small LED torches and children's toys. Alkaline chemistry suits devices that draw a modest current over a long stretch, which covers most of that list. Where a device takes two or more cells, change them all together and keep one chemistry across the compartment: a tired cell wired in series holds back the fresh ones beside it. Keeping a couple of spares in the same drawer as the remote saves the usual hunt.

Alkaline is a single use chemistry, so these cells are not made to be recharged; for kit you drain daily, a rechargeable cell earns its keep instead, while for a remote or a clock a card of alkalines is the straightforward choice. One unit of this listing is one card of five cells. The minimum order is 24, sold in multiples of 24, which suits a workshop, a letting agent or anyone restocking a stationery cupboard. It sits alongside our wider range of Energizer alkaline cells in AA, C, D and 9V, along with coin cells, so one order can cover most of the sizes in a building.

How many batteries do I actually get on one card?

Five cells in total. The card is packed as four plus one bonus cell, and all five are the same AAA alkaline cell.

Is AAA the same thing as LR03?

Yes. LR03 is the international code for an alkaline AAA cell, and older manuals sometimes list the size as R03 instead.

Can these cells be recharged?

No. Alkaline is a single use chemistry and these are not built for charging, so fit a proper rechargeable cell if that is what you need.

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

The pack states a shelf life of ten years, so unused cards can be bought ahead and kept as spares rather than used immediately.

Can I put one of these in a device beside cells that are already part used?

Better not to. In a multi cell compartment the weakest cell sets the pace, so change the whole set together and keep to one chemistry.

Do I have to order more than one card?

Yes, this line is sold to us in trade quantity, so the minimum order is 24 cards and orders go up in multiples of 24.
