Description
The CR2025 is a 3V lithium coin cell, and this listing is the Energizer version supplied on a two cell blister card. The code is a measurement as well as a name: under the IEC system for round lithium cells, 20 means 20mm across and 25 means 2.5mm thick. That matters more than it sounds, because the CR2032 sitting beside it on the shelf shares the same diameter but is 3.2mm thick. Each cell prints its own code on the face, so the surest way to order correctly is to read the one you are replacing.
Lithium coin cells of this size do the quiet jobs around a house. Car key fobs and keyless entry remotes, slim television and set top box handsets, kitchen scales, calculators, digital thermometers, small clocks and a great many watches all run on one. They sit in a sprung clip or a screw down holder, and the printed face of a coin cell is the positive side, which in most holders faces up towards the lid. A cell a fraction too thick will bow the contact, and one too thin will lose contact as the device is handled, which is why swapping thicknesses is rarely worth trying.
Lithium coin cells hold their voltage steadily rather than fading away slowly, which is what suits them to a device that draws almost nothing for months at a time. The front of the pack states 3V lithium batteries. One unit here is a sealed blister of two cells, and the minimum order is ten units, so twenty cells in all, which suits a workshop drawer or a maintenance kit rather than a single change. We stock other Energizer coin cells beside it, including CR2032, CR1220 and CR1216 lithium types and silver oxide cells.

Frequently Asked
How many cells do I actually receive?
One unit is a sealed blister card holding two CR2025 cells. The minimum order is ten units, so twenty cells in total.
Is a CR2025 the same as a CR2032?
No. Both are 20mm across, but the CR2025 is 2.5mm thick and the CR2032 is 3.2mm, so a holder sized for one may not hold the other properly.
What voltage does this cell give?
The pack states 3V lithium batteries, which is the nominal voltage for a CR type lithium coin cell of this size.
Which way round does the cell fit?
The wide printed face of a coin cell is the positive side, and in most holders it faces upwards towards the lid or the retaining clip.
Does the pack print a shelf life figure?
No shelf life figure is printed.
