Description
This is a card of six CR2025 lithium coin cells from Eveready, each one a 3V cell as marked on the pack. Lithium is the chemistry used for almost every coin cell of this size, and it gives a flat, steady voltage for most of the cell's working life rather than a slow fade, which matters in a device that either works or does not. The pack states the cells are ready to use up to 10 years in storage, so a spare set kept in a drawer should still be good when you come to need it, and the card is a child resistant pack that has to be cut open rather than pushed through.
CR2025 is one of the sizes that turns up constantly around the house and the car: key fobs, gate and garage remotes, kitchen scales, digital thermometers, calculators, tealights, bike lights and a great many watches all call for it. In the IEC numbering used on coin cells the four digits describe the size, so 2025 means 20mm across and 2.5mm thick. That is worth knowing, because 20mm coin cells come in more than one thickness and a thicker one will not sit under a lid built for this size. Check the code printed on the cell you are replacing, or on the inside of the battery door, and match all four digits rather than the first two.
The cells come on a card of six, and the minimum order is 10 cards, sold in multiples of 10, so one order brings 60 cells in. That suits a maintenance cupboard, a facilities store or a shop counter. Keep unopened cards somewhere cool and dry and away from loose metal such as coins and keys. We also stock Eveready cells in AA, AAA, C, D and 9V sizes.

Frequently Asked
Can I use a CR2025 where the device asks for a CR2032?
Not reliably. Both are 20mm across, but the 2032 is thicker, so a 2025 can sit loose in the holder and lose contact. Match all four digits.
How many cells do I actually receive?
Each card holds six 3V CR2025 cells. The minimum order is 10 cards in multiples of 10, so the smallest order brings 60 cells.
How long will they keep before I use them?
The pack states the cells are ready to use up to 10 years in storage, so buying a batch for a cupboard or a van stock is sensible.
What voltage do they give, and does it drop as they drain?
They are 3V cells. Lithium coin cells hold a fairly flat voltage through most of their life, then fall away quite quickly at the end.
How should I store the spare cards?
Keep them in the sealed card, somewhere cool and dry, and away from loose coins and keys so nothing can bridge the two faces of a cell.
