Description
Each of these four cells is a Panasonic Eneloop AAA, a nickel metal hydride rechargeable that arrives already charged. The pack prints a minimum capacity of 800mAh, and states that the cells are pre-charged with solar energy, so the set can go from the card into a device without a first charge. Eneloop is a low self discharge design: the pack states that 70% of capacity remains after ten years of storage, and that each cell can be recharged up to 2100 times. The outer card is plastic free and carries FSC certification.
AAA is the size behind the quiet, constant things in a house: remote controls, wireless keyboards and mice, doorbell transmitters, wall clocks, head torches, children's toys and game controller packs. Those are the jobs where disposables add up fastest, and where a cell that holds its charge in a drawer matters more than raw capacity. Keep a charged set of four to hand, swap them in when something goes quiet, and put the flat pair on charge. One thing worth knowing before you buy: NiMH is a 1.2V chemistry, where an alkaline AAA is 1.5V. Most household electronics run happily on that, though a few voltage sensitive items, including some older digital cameras, read the lower figure as a low battery.
These are cells on their own, so you will need a NiMH charger to go with them. Our wider Panasonic range includes an Eneloop charger that takes eight AA or AAA cells, the same cells in AA, and an eight pack of this AAA size if you want spares. Unlike the older nickel cadmium chemistry, NiMH does not need to be run down flat before it goes back on charge, so topping up a partly used set is fine. Store spares somewhere cool and dry. One order brings you four AAA cells, and the minimum order is a single pack.

Frequently Asked
Do these arrive charged, or do I need to charge them before first use?
The pack states that they are pre-charged with solar energy and ready to use, so you can fit them straight away and charge them once they run down.
Will 1.2V rechargeables work in a device that asks for 1.5V AAA batteries?
Most household electronics are designed to take either. A few voltage sensitive items, older digital cameras among them, may report a low battery sooner than they would on alkalines.
What charger do I need for these?
Any charger made for NiMH AAA cells. We stock an Eneloop charger that handles eight AA or AAA cells at once, which suits two packs of these together.
How many times can each cell be recharged?
The retail pack states up to 2100 recharges. In practice the figure depends on how hard the device works the cell and how it is charged.
What capacity are they?
The pack prints a minimum capacity of 800mAh for each AAA cell, which is a floor figure rather than a typical or best case number.
How long will they hold their charge if I leave the pack in a drawer?
The pack states that 70% of capacity remains after ten years of storage, so a spare set put aside should still be usable when you reach for it.
