Energizer CR2025 Lithium Coin Batteries

This is a single Energizer CR2025 lithium coin cell, supplied one to a pack. CR2025 is a size designation rather than a brand code, and the digits describe the cell itself: 20mm across and 2.5mm deep. That matters more than it sounds, because a CR2025 and a CR2032 share the same 20mm diameter and the same 3V output, yet the 2032 is nearly a millimetre thicker. Check the number moulded into the face of the cell you are replacing, or printed inside the device's compartment, before you order.

Coin cells of this size turn up in the small things around the house that nobody thinks about until they stop: car key fobs and garage remotes, slimline calculators, kitchen timers, digital thermometers, fitness bands, LED tea lights, and the cell that keeps the clock and settings alive on a computer motherboard. Because the CR2025 is flat and light, it also suits slim cases where a thicker cell will not let the cover close. Where a device stacks two or three cells together, change them all at the same time rather than putting a fresh cell next to a tired one.

Lithium is the chemistry to want in something you rarely open. It sits well on the shelf and holds a steady 3V, against the 1.5V of an alkaline button cell, so a CR2025 is not a swap for an LR44 or similar even where the two look close in size. You receive one cell, and the minimum order is 10, sold in multiples of 10. Our other Energizer cells cover AA, AAA, C, D and 9V, along with the thicker CR2032 coin cell.

Will a CR2025 work in place of a CR2032?

Not reliably. Both measure 20mm across and both give 3V, but the CR2032 is the thicker cell of the two, so a CR2025 can sit loose against the contacts and will run down sooner. Fit the size the device asks for.

How many cells do I receive, and what is the smallest order?

One cell per pack. The minimum order on this listing is 10, sold in multiples of 10, so the smallest purchase brings you 10 single cells rather than one.

What voltage does this cell give?

3V, as printed on the pack. That is the usual figure for a lithium coin cell and double the 1.5V of an alkaline button cell such as an LR44, which is why the two are not interchangeable.

Is the packaging child resistant?

The pack states child resistant, so the blister is made to be awkward for a small child to open. Keep loose cells away from children, as a swallowed coin cell is a medical emergency.

Which devices usually take a CR2025?

Car key fobs, garage and gate remotes, slim calculators, kitchen timers, digital thermometers, fitness bands, LED tea lights and computer motherboards. Read the code stamped on the cell you take out to be sure.
