JCB Super Alkaline AAA Batteries (MN2400) - 8 Pack

AAA cells are the small ones, and this card carries eight of them, split into two blocks of four so half can be torn off while the rest stays sealed. They are alkaline, the standard 1.5V primary chemistry that almost every household gadget is designed around, and the pack prints the reference MN2400 beside the AAA size for anyone matching a code off an old cell. The range name on the card is Super Alkaline, and the card also carries an up to seven times more power figure; the pack does not say what that is measured against, so treat it as the manufacturer's own claim rather than a tested runtime.

Most homes have a drawer of things waiting on AAAs: television and set top box remotes, a wireless mouse or keyboard, wall clocks, kitchen scales, digital thermometers, head torches, electronic toys and the keypads on doorbells and alarms. Alkaline suits that kind of work, where the current draw is low and comes in short bursts, and a remote can run for a year or more on a pair. High drain electronics such as a camera flash will empty any primary cell quickly, so keep spares to hand for those. Eight cells cover two or three small devices at once, with a few left over.

Alkaline cells are single use, so these are not for a device that expects rechargeables. Keep them somewhere cool and dry, leave them in the card until the moment they go in, and avoid mixing part used cells with fresh ones in the same device, because the weakest cell sets the pace for the rest. One unit is one card of eight; the minimum order is 12 cards, sold in multiples of 12, which works out at 96 cells. We also stock JCB alkaline cells in AA, 9V and D, along with lithium coin cells.

How many batteries do I get on one card?

Eight AAA cells in total, held as two blocks of four, so you can open half the card and leave the other four sealed until they are needed.

What code should I match against my old battery?

Check the size name first: if the old cell reads AAA it is the same size as these. The reference printed on this pack alongside the AAA size is MN2400.

Can these be recharged?

No. Alkaline is a primary chemistry, meant to be used once and replaced. Putting them in a charger risks leaking and damage, so use proper rechargeable cells where a charger is involved.

Will they suit a device that takes four cells?

Yes, and one sealed block of four covers it neatly. Fit all four at the same time from the same block rather than topping up a set with one new cell.

How long will they keep in a drawer?

The pack does not print a shelf life, so we do not quote one. Stored cool, dry and still in the card, alkaline cells hold their charge well in normal household conditions.

Do I have to order twelve cards?

Yes. This line is sold in multiples of 12 cards, so the smallest order is 12 cards, which comes to 96 individual AAA cells.
