Description
This is a four pack of JCB Recharge AAA cells, each one a nickel metal hydride rechargeable rated at 900mAh and 1.2V. The pack states they arrive charged and ready to use, so the first set can go straight into a device, and that each cell takes up to 500 charges across its working life. The 900mAh figure is capacity: it describes how much charge a cell holds between visits to the charger, rather than how hard it pushes at any one moment.
AAA is the slim cell, and it turns up in more places around a house than any size except AA: television and set top box remotes, wireless mice and keyboards, small torches, wall clocks, children's toys and games controllers. Rechargeables pay back fastest in whatever drains quickly, so if a controller or a toy eats a pair of disposables every few weeks, that is the device to move over first. A nickel metal hydride cell sits at 1.2V nominal where an alkaline sits at 1.5V; most equipment runs perfectly well on it, though a few devices with a voltage based low battery indicator may read lower than you expect even on a full cell.
These need a charger made for nickel metal hydride cells, and any NiMH charger with AAA bays will do the job. Charge all four together where you can, so the set stays matched and ages at the same rate, and it is worth keeping a second set charged if a device is in constant use. One unit of this listing is a single pack of four cells. The minimum order is 10, sold in multiples of 10, which means 40 cells in the smallest order we can take. If you run AA equipment as well, the JCB Recharge AA is on our shelves in the same four pack.

Frequently Asked
Do these arrive charged, or do I need to charge them first?
The pack states they are charged and ready to use, so the first set can go into a device straight away. Give them a full charge after that first run down.
Will 1.2V cells work in something designed for 1.5V alkalines?
In most equipment, yes. Nickel metal hydride cells are 1.2V nominal by chemistry, and the great majority of AAA devices run on them without any trouble at all.
What does the 900mAh rating actually mean for me?
It is the capacity of the cell, meaning how much charge it stores between charges. A higher figure means longer between visits to the charger in the same device.
What sort of charger do these need?
Any charger built for nickel metal hydride cells with AAA bays. Charging the whole set of four together keeps the cells matched, which helps them age at the same rate.
How many times can each cell be recharged?
The pack states up to 500 charges. Real world figures depend on how deeply the cells are run down and how often they are cycled in use.
How many cells do I receive, and what is the smallest order?
One unit is a pack of four cells. The minimum order is 10 packs, sold in multiples of 10, so the smallest order is 40 cells.
