Description
These are AAA cells from Energizer's Ultimate Lithium range, boxed ten at a time. The chemistry is what you are paying for. A lithium primary cell of this size is lighter than the alkaline equivalent, holds a steadier voltage as it drains rather than tailing off gradually, and keeps working in cold conditions that slow alkaline chemistry down. The pack prints a 20 year shelf life.
AAA is the size that ends up in the small electronics that drain a cell quickly: digital cameras and flashguns, head torches, wireless door and window sensors, smart thermostats, blood pressure monitors, games controllers and handheld GPS units. Those are the jobs where a lithium cell earns its higher price, because a high current draw is where alkaline chemistry gives up its remaining capacity least willingly. For a wall clock or a rarely used remote control, a standard alkaline AAA will do the same work for less money, so it is worth keeping both on hand and putting the lithium cells where the load is heaviest.
One unit of this listing is a single box of ten cells, and the minimum order is 12 boxes, sold in multiples of 12, which works out at 120 cells at a time. That suits a workshop, a letting agent or a site store more than a kitchen drawer. Every cell carries 1.5V, the same nominal voltage as an alkaline AAA, so nothing in the device needs to change. We also stock Energizer alkaline AAA, AA, C and D cells, 9V alkaline and lithium coin batteries if a cheaper chemistry suits the job better.

Frequently Asked
Will these work in anything that takes an ordinary AAA battery?
Yes. AAA is a standard size at 1.5V nominal, so these sit in the same holders, clips and sprung contacts as alkaline AAA cells.
How many cells do I actually receive?
Each box holds ten AAA cells. The minimum order is 12 boxes, sold in multiples of 12, so 120 cells arrive in one go.
How long will they keep before I use them?
The pack prints a 20 year shelf life.
Can these be recharged?
No. These are single use lithium cells, and putting a primary cell on a charger risks heat, leakage and damage to the charger itself.
Can I mix them with alkaline cells in the same device?
Better not to. Mixing chemistries, or old cells with new, means one cell runs down ahead of the others and the set performs unevenly.
