Description
These are AAA nickel-metal hydride rechargeable cells from the Energizer Recharge Power Plus range, rated at 700mAh and supplied ten to a box. NiMH cells run at a nominal 1.2V rather than the 1.5V of a disposable alkaline, and that lower figure is normal for the chemistry rather than a sign of a weak cell. The 700mAh capacity is the charge the cell holds between top-ups, so a higher figure means longer between visits to the charger rather than more power at any one moment. The pack states the cells arrive pre-charged, so a set can go straight into a device instead of waiting overnight, and that they are made with 4% recycled batteries.
AAA is the slim cell used by remote controls, wireless keyboards and mice, digital thermometers, children's toys, head torches and the smaller games controllers. Rechargeables earn their keep in anything that empties a set quickly or predictably: a controller used every evening, a mouse in daily office use, a toy played with constantly. For a wall clock that runs a year on one set, a disposable alkaline is usually the simpler choice. A box of ten suits a household or an office that wants a charged set waiting while another set is on charge, which is where rechargeable cells save the most time.
The pack states these cells last up to four times longer in digital cameras than Energizer basic alkaline. They are charged in a charger made for NiMH cells, and we also list the Energizer 1 Hour Charger supplied with four AA 2300mAh cells. Alongside this listing we stock Energizer alkaline cells in AA, AAA, C, D and 9V, plus lithium and silver oxide coin cells. One unit of this listing is a box of ten cells, and the minimum order is twelve units, sold in multiples of twelve.

Frequently Asked
How many cells do I get, and how many boxes do I have to order?
One unit is a box of ten AAA cells, and the minimum order is twelve units sold in multiples of twelve, which comes to 120 cells.
Do I need to charge them before I use them?
The pack states they are pre-charged, so a set can go into a device straight away. Put them on charge once they first run down.
Will 1.2V be enough in a device that asks for 1.5V batteries?
1.2V is the nominal voltage of NiMH chemistry rather than a shortfall of this cell. NiMH holds its voltage fairly steadily in use, while an alkaline falls away from 1.5V as it drains.
What does the 700mAh figure actually tell me?
It is the amount of charge the cell stores, so it indicates how long a device runs between charges rather than how bright or fast that device will be.
What sort of charger do these need?
A charger made for NiMH cells that takes the AAA size. We also list the Energizer 1 Hour Charger, which is supplied with four AA 2300mAh cells.
