Description
This is a AAA alkaline cell, code LR03, rated at 1.5V, and it is priced and sold as a single cell rather than as a pack. AAA is the slim penlight size that sits below AA, and every cell built to the LR03 standard shares the same dimensions, so it will drop into any compartment marked AAA, LR03 or Micro. Alkaline is the everyday chemistry for this size: it holds more energy than a zinc carbon cell of the same dimensions and copes better with the steady current a small motor or a backlit display asks for. The pack also states 0% mercury and cadmium.
AAA cells run most of the small electronics in a house: television and set top remotes, wall clocks, digital thermometers, a wireless mouse or keyboard, kitchen scales, blood pressure monitors, children's toys, head torches and the doorbell push by the front door. Buying loose cells rather than blister packs suits anyone keeping a drawer stocked, a maintenance cupboard topped up, or a classroom, office or holiday let running. Because the price is per cell, you take the number the job actually needs instead of rounding up to whatever a retail pack happens to hold.
One unit here is one cell, and the minimum order is 10, sold in multiples of 10, so the smallest quantity we can send is ten cells and it scales up in tens from there. Fit cells as a matched set rather than putting a fresh one alongside a part used one, and keep the chemistry the same across a device, because a mixed set tends to be held back by its weakest cell. We stock other JCB cells alongside this one, including AA, AAAA, D, 9V, LR44 and CR2032 coin cells, and rechargeable AA, so one order can cover most of the sizes in the house.

Frequently Asked
How many cells do I get for the price shown?
The price is for one cell. The minimum order is 10, sold in multiples of 10, so ten cells is the smallest quantity we can send out.
Will an LR03 cell fit a device marked AAA or Micro?
Yes. AAA, LR03 and Micro are three names for the same standard cell size, so any compartment carrying one of those markings takes this cell.
Can I recharge these once they are flat?
No. Alkaline cells are single use and should go to a battery recycling point when spent. We list JCB rechargeable AA cells separately if you want a rechargeable option.
What does alkaline give me over a zinc carbon cell of the same size?
Alkaline chemistry stores more energy in the same dimensions and holds up better under steady current, so it generally runs longer in remotes, mice, toys and small torches.
Does the manufacturer state a shelf life for these cells?
No shelf life figure is printed for this line, so we do not quote one. Keep spare cells somewhere cool and dry until they are needed.
Can I put a new cell in alongside one that is already part used?
Better not to. A device runs only as well as its weakest cell, so changing the whole set together gives far more predictable running time.
