JCB AAA Batteries (LR03) Super Alkaline - 10 Pack

A pack of ten JCB AAA alkaline cells, the slim 1.5V batteries that live in remote controls, wall clocks, wireless mice and children's toys. AAA is the size; the same cell is listed as LR03 in many instruction manuals, and the JCB card also prints the MN2400 code, so if your device asks for any of those you have the right battery. Alkaline is the chemistry, the standard single use choice for everyday household kit. The card describes the range as Super Alkaline and Built To Last, and prints two claims we quote as the pack states them: up to seven times more power, and up to 400 photos in a digital camera.

Ten is the quantity that stops you hunting through a drawer at the wrong moment. It covers a television remote, a couple of clocks, a keyboard and a torch with spares left over, and AAA is the size most homes run out of first, because so many small devices take two or three at a time. Alkaline cells are single use and cannot be recharged, so a device that is worked hard every day may be better on rechargeable cells; for low and moderate drain items such as remotes and clocks, alkaline is the straightforward answer.

The ten cells arrive on a printed hanging card, held in a clear blister so you can see and count them at a glance. Fit them the way the compartment shows, matching the plus end to the plus marking, and keep part used cells out of the same compartment as fresh ones, since a device runs only as well as the weakest cell in it. This listing is sold in multiples of ten packs, so it suits a home stocking up or a workplace keeping its battery drawer topped up.

How many batteries do I actually receive?

One unit of this listing is a card of ten AAA cells. The listing is also sold in multiples of ten, so the smallest order placed is ten cards.

Is AAA the same thing as LR03 or MN2400?

Yes. AAA is the common name, LR03 is the code used for the alkaline version in many manuals, and MN2400 is the equivalent code printed on this pack.

Can these cells be recharged?

No. Alkaline cells are a single use chemistry and are not designed to be put on a charger. If you want to recharge, choose a rechargeable AAA cell instead.

What voltage is an AAA alkaline cell?

A nominal 1.5V per cell, which is what small household electronics expect. A device taking three AAA cells is therefore running on 4.5V in total.

What sort of devices do AAA cells suit?

Remote controls, wall clocks, wireless keyboards and mice, small torches, digital thermometers and a great many children's toys all take AAA cells.

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

Better not to. A device draws through all its cells together, so a part used cell sitting beside fresh ones limits how long the set lasts.
