Energizer CR2032 Lithium Coin Batteries - 6 Pack

This is a card of six Energizer CR2032 lithium coin cells, a 3V button battery used across a wide spread of small electronics. The code names the size: under the international naming scheme for coin cells, the 20 stands for 20mm across and the 32 for 3.2mm thick. The CR prefix marks lithium chemistry, which is what lets a cell this small give 3V rather than the 1.5V of an alkaline button cell. Each battery sits in its own bubble on the card, so you can lift one out and leave the other five sealed.

Before ordering, read the code off the cell you are replacing: it is printed on the flat positive face. A CR2025 or CR2016 shares the same 20mm diameter but is thinner, so it can sit low in the holder and lose contact. The 2032 is the cell behind car key fobs and garage remotes, kitchen and luggage scales, digital thermometers and tyre gauges, calculators, watches, fitness trackers, LED tealights and the small backup battery on a computer motherboard that keeps the clock and BIOS settings while the machine is unplugged.

One unit of this listing is a single card of six cells, and the minimum order is ten cards sold in multiples of ten, so the smallest purchase brings sixty batteries. That suits a repair bench, a workshop or a household that would rather keep spares in a drawer than hunt for one on a Sunday. Stored unopened, dry and at room temperature, lithium coin cells lose charge slowly. Coin cells are a swallowing hazard, so keep them in the pack and well out of reach of young children and pets. It sits alongside our wider Energizer range, which runs from the same 2032 in a 12 pack to the smaller CR1216 and CR1220 coin cells and the everyday AA, AAA, C, D and 9V sizes.

Will a CR2032 fit a device that specifies a CR2025 or CR2016?

No. All three measure 20mm across, but the 2032 is 3.2mm thick against 2.5mm and 1.6mm, so it will not seat in a shallower holder and a thinner cell can lose contact in a 2032 one. Match the code exactly.

How many batteries do I actually receive?

Each unit of this listing is one card holding six CR2032 cells. The minimum order is ten cards in multiples of ten, so the smallest order brings sixty cells in total.

What voltage does one cell give?

Each cell gives 3V, as printed on the pack. That is the usual output for a lithium coin cell, twice the 1.5V you get from an alkaline cell of similar shape.

Which devices usually take this size?

Car key fobs and garage remotes, kitchen and luggage scales, digital thermometers and tyre gauges, calculators, watches, fitness trackers, LED tealights, and computer motherboards that keep the clock running while unplugged.

Does the manufacturer state a shelf life?

Energizer prints no shelf life figure on this pack, so we state none. Kept unopened, dry and at normal room temperature, lithium coin cells lose charge slowly in storage.
