Description
The CR2032 is the coin cell most devices mean when they ask for a 2032, and this one comes from JCB on a single cell card. It is a lithium cell rated at 3V, and both the code and the voltage are printed on the cell face, so you can check them against the battery you are replacing. The number in the designation is the size: a 2032 measures 20mm across and 3.2mm thick, which is what separates it from the thinner 2025 and 2016 cells that share the same diameter. One card, one cell.
Coin cells of this size turn up all over the house and the car. Key fobs are the common one, and a fob that needs a second press or a firmer press is usually asking for a fresh cell rather than a new key. The same cell keeps the clock and the settings alive on a computer motherboard while the machine is unplugged, and it sits behind digital kitchen scales, thermometers, tyre pressure gauges, garage door remotes, fitness bands and LED tea lights. If a device takes a small screwdriver to open a round hatch, a 2032 is a fair first guess.
Lithium coin cells hold their voltage fairly flat through most of their working life rather than fading off gradually, so a device often behaves normally and then stops within a day or two. JCB does not print a shelf life figure on this pack, so none is quoted here. Each unit is a single cell, and the minimum order is ten units, sold in multiples of ten, which suits a workshop drawer or a small stockroom better than a one-off swap. We also stock JCB lithium coin cells in CR2016 and CR2025, and CR2032 in a six pack. Coin cells are a swallowing hazard, so keep them out of reach of children and take spent cells to a battery recycling point.

Frequently Asked
Which devices usually take a CR2032?
Car key fobs, computer motherboards, digital kitchen scales, thermometers, tyre gauges, fitness bands and small LED lights are the usual homes for a 2032.
How many cells do I receive per unit?
One. Each unit of this listing is a single CR2032 cell on its own card, not a strip or a multipack of several cells.
Will this fit a holder that had a CR2025 in it?
A 2032 is the same 20mm diameter but thicker at 3.2mm, so it may not seat correctly. Fit the code your device asks for.
What voltage does it give?
3V, as marked on the cell itself. Lithium coin cells hold that voltage fairly steadily until close to the end of their working life.
Can a CR2032 be recharged?
No. Lithium coin cells of this type are single use, so never put one in a charger. Replace it and recycle the spent cell.
