Description
A pair of 3V lithium coin cells in the CR2032 size, which is the one most households end up hunting for at some point. The code is really a measurement: the 20 means the cell is 20mm across and the 32 means it is 3.2mm thick, so anything marked CR2032 fits the same holder regardless of who made it. Lithium is what gives a coin cell its long, flat discharge, sitting close to full voltage for most of its working life rather than dimming away gradually, and it holds up better in the cold than a button cell of other chemistries. Each cell is printed CR2032 3 volts.
CR2032 turns up in more places than any other coin cell. Car key fobs and alarm remotes are the common ones, along with kitchen and luggage scales, digital thermometers, blood glucose meters, fitness bands, calculators, LED tea lights and the small backup cell on a PC motherboard that keeps the clock and settings alive. If you are replacing one, lift the old cell out and read the face: the code is stamped on it. Keeping a spare pair in a drawer is sensible, because a dead fob or a flat motherboard cell rarely gives you notice, and the two cells here are not linked, so one can wait while the other works.
One unit is a blister card of two cells. These are sold in multiples of ten cards, so the smallest order is ten packs, twenty cells in total, which suits a workshop, a lettings manager or anyone restocking a spares box. They sit alongside our other Energizer coin cells, including CR1216 and CR1220 lithium, LR44 alkaline, SR626 silver oxide and a 12 pack of this same CR2032.

Frequently Asked
How many cells do I actually receive?
One unit is a single blister card holding two CR2032 cells. The minimum order is ten cards, so the smallest quantity that can be bought is twenty cells in total.
How do I check my device takes a CR2032?
Take the old cell out and read its face. The code is stamped on the flat positive side, and any cell reading CR2032 will seat in the same holder whoever made it.
What voltage do these give?
Each cell is 3V, and the pack states 3V lithium batteries. Lithium coin cells hold close to that figure for most of their working life instead of tailing off early.
Can I fit a CR2025 instead if that is what I have?
A CR2025 is the same 20mm across but only 2.5mm thick rather than 3.2mm, so it holds less energy and may sit loosely in the contacts. Stay with the size the device asks for.
