Energizer CR2032 Lithium Coin Batteries - 12 Pack

This listing is one box of twelve CR2032 lithium coin cells from Energizer, the 3V button cell that sits inside more of the house than most people would guess. Lithium is the chemistry worth looking for in a coin cell: it gives a steady 3 volts rather than the 1.5 volts an alkaline button cell produces, and it loses very little charge simply sitting in a drawer. That matters on a twelve pack, because most people will not use all twelve at once, and the box prints a 10 year shelf life. The cells are single use rather than rechargeable.

A CR2032 turns up in car key fobs, garage and alarm remotes, kitchen scales, digital thermometers, blood glucose meters, tyre pressure sensors, bike lights, LED tea lights, small calculators and the CMOS position on a computer motherboard, where it keeps the clock and the settings while the machine is unplugged. Twelve is a sensible quantity if you keep a spares drawer at home, run a workshop or look after the office kit, since these are the cells that always seem to die on a Sunday. Keep them in the box rather than loose in a drawer; the packaging is child resistant, which the pack states, and loose coin cells and small children are a bad combination.

Before you order, read the code off the flat face of the cell you are taking out. Coin cells look alike, but the four digits describe the size: a 2032 is 20mm across and 3.2mm thick, so a 2025 or a 2016 will rattle or sit low, and a thicker cell can stop a battery door closing. The printed face is the positive terminal and usually faces up in a holder. We sell this as one pack of twelve, minimum order one, and it sits alongside our other Energizer lithium coin cells including CR1216, CR1220 and CR1225.

Which devices take a CR2032?

Car key fobs, alarm and garage remotes, kitchen scales, digital thermometers, glucose meters, tyre pressure sensors, bike lights and the CMOS slot on a computer motherboard are the common ones.

How many cells do I actually receive?

Twelve. One unit of this listing is a single retail box holding twelve CR2032 cells, and the minimum order is one box.

Will a CR2032 replace a CR2025 or a CR2016?

No. All three are 20mm across, but the last two digits give the thickness, so a 2032 at 3.2mm is taller and may not fit a holder built for a thinner cell.

How long will the spare cells keep before I use them?

The pack states a 10 year shelf life. Lithium coin cells hold their charge well in storage, so buying twelve for a spares drawer is not wasteful.

Can these be recharged?

No. The CR prefix marks a primary lithium cell, which means it is designed to be used once and then recycled rather than put on a charger.

Which way round does the cell go in?

On a coin cell the wide printed face is the positive terminal, so in most holders the side carrying the CR2032 marking faces upwards towards you.
