Duracell Plus AAA Batteries (LR03) - 4 Pack

A pack of four AAA alkaline cells from the Duracell Plus line. AAA is the slimmer of the two common stick cells, and it is coded LR03 under the international standard and MN2400 under Duracell's own numbering. Both codes are printed on the pack, so if a device manual or the spent cell you are replacing quotes either one, these are the right fit. Each cell gives a nominal 1.5V, the standard output for alkaline chemistry in this size. The pack names Power Boost Actives and prints an up to 100% extra life claim, without printing what that figure is measured against.

AAA is the cell that keeps a house running quietly: television and set top box remotes, wall clocks, wireless keyboards and mice, digital thermometers, kitchen scales, door chimes, small torches and a great many children's toys. Alkaline chemistry suits that kind of work, where the current drawn is low to moderate and the device may sit for weeks between uses. A high drain device such as a camera flash will empty any alkaline cell quickly; for those, a rechargeable is the better answer. Four cells in a pack covers two devices that take a pair each, or one that takes four.

One unit of this listing is the four cell pack, and the minimum order is ten of them, so the smallest purchase brings forty cells. That suits an office, a lettings manager or anyone who would rather not hunt for AAA at the back of a drawer. Two habits make a set last: replace all the cells in a device together rather than mixing a fresh one with a tired one, and take the cells out of anything you are shelving for a season. The manufacturer does not print a shelf life figure on this pack. These sit alongside our wider Duracell range, which includes AA Plus Power cells and lithium coin cells such as CR2032.

My device asks for LR03 or MN2400. Are these the right cells?

Yes. LR03 is the international code for an AAA alkaline cell and MN2400 is Duracell's own reference for the very same size, and both are printed on this pack.

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

Each pack holds four cells. The minimum order on this listing is ten packs, sold in multiples of ten, which comes to forty cells in total.

Can I use these where rechargeable AAA cells are currently fitted?

They fit the same compartments, as the size is identical. A rechargeable AAA gives around 1.2V against the 1.5V of an alkaline cell, so a few voltage sensitive devices behave differently.

Is AAA the same as AA?

No. AAA is the slimmer and shorter cell of the two, holds less energy and will not sit properly in an AA compartment. Check the marking inside the battery bay first.

How long will one set last?

The manufacturer does not print a runtime figure on this pack, and it depends entirely on the device. A wall clock draws very little while a game controller draws a great deal.

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

Better not to. Mixing a fresh cell with a tired one means the weaker cell sets the pace, and the whole set comes up short sooner than it should.
