Description
Energizer's Recharge Universal cells in AAA size, four to a blister pack. They are nickel metal hydride, or NiMH, rated at 1.2V with a capacity of 600mAh, and the pack states they come pre-charged, so they will run a device straight away rather than needing a night on charge first. The pack marks them AAA-HR03; HR03 is the international code for a rechargeable AAA, and it is worth knowing because some device manuals list the code rather than the letter size. The 1.2V figure is standard for NiMH and sits below the 1.5V of a single use alkaline, which is the usual reason people hesitate; NiMH holds its voltage steadily through most of the discharge instead of tailing off.
These suit the devices that quietly drain a set of batteries over months: remote controls, wall clocks, wireless keyboards and mice, kitchen scales, doorbell pushes and children's toys. The pack describes them as suitable for everyday devices, and 600mAh sits at the everyday end of the AAA rechargeable scale rather than the high capacity end, so match them to steady low drain work and keep a larger cell for anything that pulls hard and fast. Four cells covers most two cell and four cell devices around the house.
You will need a NiMH charger; these cells are not single use, so a flat set goes back on charge rather than in the bin. The pack states they are made with 7% recycled batteries and that the packaging is recyclable. One unit is a pack of four cells, and our minimum order is twelve units, worth knowing if you are keeping a workshop, a classroom or a holiday let stocked. They sit alongside the wider Energizer range we stock, which runs from AA and AAA alkaline cells through lithium and silver oxide coin cells to a charger supplied with AA cells.

Frequently Asked
Will these work in a device that normally takes 1.5V alkaline AAA batteries?
Most everyday electronics are built to run on NiMH at 1.2V, and the pack states the cells are suitable for everyday devices. Where a manual asks for alkaline only, follow the manual.
Do I need to charge them before first use?
The pack states they are pre-charged, so you can fit them straight from the blister. Once they run flat, a NiMH charger brings them back for the next run.
What sort of charger do they need?
Any charger made for NiMH cells that takes the AAA size. No charging time is printed on this pack, so work to the instructions supplied with your own charger.
Is HR03 the same thing as AAA?
Yes. HR03 is the international code for a rechargeable AAA cell and the pack prints both. LR03 is the code you will see on the single use alkaline version of the same size.
What does the 600mAh figure actually tell me?
It is the capacity, meaning how much charge the cell stores. A higher figure runs longer between charges, and 600mAh is aimed at steady, lower drain devices rather than power hungry ones.
How many cells do I receive, and what is the minimum order?
Each pack holds four AAA cells. The minimum order is twelve packs, sold in multiples of twelve, which works out at forty eight cells in total.
