Duracell Plus Power AAA Batteries (MN2400) - 16 Pack

These are AAA alkaline cells from the Duracell Plus Power range with Power Boost Actives, supplied sixteen to a pack. AAA is the slim cell, roughly the width of a pencil, and it is the size most remote controls, wall clocks, computer mice and small handheld gadgets are built around. Alkaline is the everyday chemistry: it sits patiently in a drawer between uses, it works at normal room temperatures, and it is meant to be used once and then recycled rather than put back on charge. Each cell gives the usual 1.5 volts for the size, so it drops into anything specified for AAA.

Sixteen cells is a household quantity rather than a one job purchase. It covers the television and set top box handsets, a wireless keyboard and mouse, kitchen scales, a digital thermometer, children's toys and the small torch in the kitchen drawer, with a few left over for whatever runs flat next. The card has an open and close tab on the front, so once you have broken into it the remaining cells stay held in place rather than rolling loose, and their terminals stay apart until you need them.

The front of the pack prints an up to 100 percent extra life claim for its Power Boost Actives, without setting out on the face what that figure is measured against, so read it as the manufacturer's own comparison. No shelf life figure appears on the front of the pack, and the manufacturer does not state one elsewhere. These cells are not rechargeable and should not go into a charger. One unit of this listing is a single pack of sixteen, and the minimum order is ten packs in multiples of ten, which works out at 160 cells. It sits alongside our wider Duracell range of AA Plus Power cells, lithium coin cells, silver oxide watch batteries and hearing aid cells.

How many cells do I actually receive?

One unit of this listing is a single card holding sixteen AAA cells. The minimum order is ten of those packs, so a first order brings 160 cells in total.

What code do these cells carry?

The pack prints MN2400, which is the manufacturer's own reference for this AAA cell. If your device asks for AAA batteries, this is the right size for it.

Can I put them on charge when they run flat?

No. These are single use alkaline cells, so run them until flat and then take them to a battery recycling point rather than attempting to recharge them.

What voltage does each cell give?

Each cell gives 1.5 volts, the standard output for an alkaline AAA, so a device taking two cells in series sees 3 volts in total.

Are these a sensible choice for something in constant heavy use?

Alkaline cells suit remotes, clocks, toys, torches and scales. For constant heavy use many people prefer rechargeables, and our Duracell chargers ship with rechargeable AA and AAA cells.

What does Power Boost Actives mean?

It is the manufacturer's name for this Plus Power range. The pack claims up to 100 percent extra life, without printing on the front what that figure is compared against.
