Duracell Recharge AAA Batteries (HR03) - 4 Pack

These are Duracell Recharge cells in AAA size, four to a blister pack, each rated at 750mAh. Milliamp-hours are the number worth reading on a rechargeable: they describe how much charge a cell holds between top-ups, not how hard it pushes, so a cell of this capacity goes further in a low-drain device such as a remote control than in a high-drain one such as a games controller. The pack prints the codes HR03 and DC2400, and those are what to match against the code in your device manual or on the cell you are taking out. The outer carton prints "Lasts 5 years in storage" and the blister prints "Lasts 3 years guaranteed".

Rechargeable AAA cells make most sense in the things that empty batteries fastest, or the things you would rather not keep buying cells for: games controllers, wireless mice and keyboards, head torches, children's toys, remote controls and kitchen timers. Four cells cover one device that takes four, or two devices that take a pair each, and if you buy a second pack you can keep one set on charge while the other is in use. They suit a home office drawer, a family kitchen, and anywhere a flat battery stops something mid-use.

A charger is not included, so you will need one that accepts rechargeable AAA cells. AAA is a standard size, so these fit the same compartments as disposable AAA cells. The pack does not print a charge time or a number of charge cycles, so we do not quote either. Store spare cells somewhere dry and away from coins and keys, as with any battery, and keep a set together so the cells age at the same rate rather than mixing an old one with a fresh one. Each listing unit is one pack of four, ordered in multiples of ten packs.

What size are these, and what code should I match?

They are AAA cells, and the blister prints the codes HR03 and DC2400. Match one of those against the code in your device manual or on the cell you are replacing.

Is a charger included?

No. This listing is four cells only, so you will need a charger that accepts rechargeable AAA cells before you can put them back into service.

What does the 750mAh figure actually tell me?

It is capacity, meaning how much charge the cell holds between top-ups. A higher figure runs a given device for longer; it does not make the device brighter or faster.

How many cells do I get, and can I order a single pack?

One unit is a pack of four cells. The minimum order on this line is ten units, sold in multiples of ten, so the smallest purchase is ten packs.

How long will they hold their charge if I put them in a drawer?

We quote only what is printed. The outer carton states five years in storage and the blister states three years guaranteed, so those are the two figures the manufacturer prints.

Is the voltage or the cell chemistry printed on the pack?

Not in words. The pack gives the size, the capacity and the codes, so we do not state a voltage or a chemistry name that the manufacturer has not printed.
