Description
The CR2025 is a 3V lithium coin cell, and this listing is the two cell retail pack. The pack is coded DL/CR2025, which is one cell under two naming conventions: DL is the older manufacturer prefix and CR the IEC designation. The IEC code doubles as a size, because the first two digits give the diameter in millimetres and the last two the height in tenths of a millimetre, so a CR2025 measures 20mm across and 2.5mm thick. Lithium chemistry is what holds a cell this small at a steady 3V, where an alkaline button cell of similar size gives 1.5V.
Cells this size sit behind a car key fob, inside slim remote controls, calculators, digital thermometers, kitchen scales, fitness bands and the small clock battery on a computer motherboard. The check worth making before you buy is thickness. A CR2025 and a CR2032 share the same 20mm diameter and the same 3V, so they look interchangeable, but the 2032 is 3.2mm thick and will not seat under a clip cut for a 2.5mm cell. Read the code stamped on the face of the old cell and match it exactly. Handle a fresh one by the edges, since marks on the flat contact faces can make for a poor connection.
Each pack holds two cells, and the front of the pack is marked as a baby secure pack and battery, with a keep out of reach of children warning printed beside it. Our minimum order here is 10, sold in multiples of 10, so one order brings 20 cells: sensible for a maintenance box or a technician's drawer rather than a single swap. It sits alongside our wider range of Duracell coin cells, which includes lithium CR1616, CR1620, CR1632, CR2016, CR2032 and CR2450, silver oxide SR621, SR626, SR920 and SR927, and alkaline LR44 and LR54.

Frequently Asked
Is a CR2025 the same as a CR2032?
No. Both are 3V lithium cells of 20mm diameter, but the 2032 is 3.2mm thick against 2.5mm here, so the two are not always swappable in a holder.
What does the DL/CR2025 code on the pack mean?
DL is the older manufacturer prefix and CR the IEC designation for a lithium coin cell. Both refer to the same cell, so either marking on your old battery matches this one.
How many cells do I actually receive?
Two cells per pack. Our minimum order is 10 packs in multiples of 10, so the smallest order brings you 20 cells in all.
Can I use this in place of a 1.5V button cell such as an LR44?
No. This cell supplies 3V, double the voltage of an alkaline button cell, and fitting the wrong chemistry can damage the device or stop it working.
Is a shelf life figure given for these?
The manufacturer does not print a shelf life on this pack, so we do not quote one. Store the cells in their unopened blister, away from heat and loose metal.
Which devices commonly take a CR2025?
Car key fobs, slim remote controls, calculators, digital thermometers, kitchen and luggage scales, fitness bands, LED tealights and computer motherboard clocks all use this size.
