JCB Super Alkaline AAA Batteries (LR03) - 18 Pack

This is JCB's Super Alkaline AAA cell, supplied eighteen to a single bumper card. Each one is a standard 1.5V alkaline round cell in the AAA size, printed AAA/LR03 on the body with the MN2400 code on the card header. All three references name the same cell, so whether your device manual asks for LR03, MN2400, Micro or simply AAA, this is the one it wants. The card also prints an 'up to eight times more power' line; it does not name what that is measured against, so read it as the manufacturer's own wording rather than a runtime you can plan around.

AAA is the slim cell, and it runs the small, low-drain things scattered around a home: television and set-top box remotes, wall clocks, wireless mice and keyboards, kitchen scales, digital thermometers, children's toys, head torches and the little reading lights that live beside a bed. Eighteen cells is more than any one device needs, which is the point of a bumper card: the drawer stays stocked when three remotes give up in the same fortnight. In an office, a classroom or a holiday let it removes the short-notice trip out for a pair of cells.

Alkaline cells are single-use, so these are not for a charger. Devices run best on a matched set: change every cell in a compartment at the same time rather than mixing part-used cells with fresh ones, and take the cells out of anything being put away for a season. JCB does not print a shelf life on this card. One unit of this listing is the card of eighteen cells; the minimum order is twelve cards, sold in multiples of twelve. Alongside it we stock JCB cells in AA, AAAA, D and 9V, lithium coin sizes and rechargeable AA.

Is AAA the same thing as LR03 and MN2400?

Yes. AAA is the common name, LR03 is the international code for the alkaline version, and MN2400 is the trade code printed on the card header. All three describe this one cell.

My appliance manual asks for a 1.5V Micro cell. Will these fit?

Micro is simply another name used for the AAA size, most often on European appliance documentation. The cell measures the same and delivers the same 1.5V, so it is the correct choice.

Can I put these on charge once they run flat?

No. Alkaline cells are made for single use and must not go in a charger. If you want cells you can top up repeatedly, choose a rechargeable NiMH AAA instead.

How many cells do I actually receive, and what is the smallest order?

One unit of this listing is a bumper card holding eighteen AAA cells. The minimum order on this line is twelve cards, bought in multiples of twelve.

What sort of devices suit alkaline rather than another chemistry?

Alkaline chemistry is at its most economical in low and moderate drain equipment such as remotes, clocks, toys and small torches, where cells are changed occasionally rather than weekly.
