Description
Four AAA cells to a card, each one a 1.5 volt zinc battery marked AAA/R03 on the wrapper. The R03 code is the one to check against the cell you are replacing: it is the international designation for a zinc AAA, and it sits beside the familiar AAA name rather than standing in for something different. Zinc sits at the everyday end of the battery shelf, suited to steady, modest current rather than heavy bursts, and the composition is printed across the front of the card so there is no guessing about what you have picked up.
These suit the quiet appliances that sip power over months rather than draining a cell in an afternoon: television and set top box remotes, wall clocks, a kitchen timer, a door chime push, a small torch kept in a drawer. The card is explicit about the other end of the scale, printing that these cells are not suitable for digital cameras or motorized devices, and that is worth taking at face value. A camera flash or a motorised toy pulls a heavy current in short bursts, and that kind of work is where an alkaline cell earns its higher price.
Each card holds four cells and we sell the card as one unit, with a minimum order of ten cards, so a first order brings forty AAA batteries into the cupboard. That is a sensible quantity for an office, a holiday let or a household that would rather not hunt for a spare on a Sunday evening. It is good practice to change all four cells in a device together rather than mixing a fresh one with a tired one. Our wider JCB battery range runs to AA and D sizes, 9V blocks, lithium coin cells and rechargeable AA and AAA, so one order can cover most of what a house takes.

Frequently Asked
Is R03 the same thing as AAA?
Yes. R03 is the international code for a zinc AAA cell, and both markings appear on these wrappers, so a device asking for either will take them.
Can I use these in a digital camera or a motorised toy?
No. The card prints that these cells are not suitable for digital cameras or motorized devices, because those pull a heavy current in short bursts.
Will they work in anything that takes an alkaline AAA?
They are the same AAA size at the same 1.5 volts, so they fit physically. Choose alkaline instead for anything that draws power hard.
Can these be recharged?
No, zinc cells are single use. If you want cells you can put back on charge, our JCB Recharge 650mAh AAA batteries (HR03) are the ones to look at.
How many cells do I actually receive?
Each card holds four AAA cells, and the minimum order is ten cards, so the smallest order brings forty cells in total.
Does the pack print a shelf life?
The card carries no shelf life figure, so we do not quote one. The manufacturer does not state a storage life for this line anywhere we can point at.
