Eveready CR2016 Lithium Coin Batteries - 6 Pack

The CR2016 is a 3V lithium coin cell, and this blister holds six of them. The code itself tells you the size, because a coin cell number reads as diameter and then thickness, so a CR2016 is 20mm across and 1.6mm deep. That thickness matters more than anything else when you are replacing one, since a CR2032 shares the same 20mm diameter and will not sit properly in a compartment built for a 1.6mm cell. Lithium chemistry is what gives a cell this small its 3V output and a steady voltage as it drains, rather than the slow fade of a zinc button cell.

These are the cells behind the small jobs around a house: car key fobs and remote handsets, slim calculators, digital thermometers, kitchen scales, fitness trackers and musical greetings cards. Check the old cell before you order, as the code is printed on the flat positive face of almost every coin cell. Fitting one is straightforward, because the printed side is the positive side and it faces the marked plus contact or the spring clip in the holder. Six in a pack means you can change a set of matched devices in one go and keep the rest for later.

The pack states that these cells are ready to use up to 10 years in storage, so a spare kept in a drawer should still be good when you come to need it. The blister is child resistant and needs scissors to open, which is the right precaution with cells this size. This listing is one pack of six, with a minimum order of ten packs sold in multiples of ten, which comes to sixty cells in the smallest order. We also stock Eveready Gold cells in AA, AAA, C, D and 9V, and Super Heavy Duty in the same sizes.

Is a CR2016 the same as a CR2032?

No. Both are 20mm in diameter, but the CR2032 is twice as thick at 3.2mm against 1.6mm here, so the two are not interchangeable in either direction.

What sort of devices take a CR2016?

Car key fobs, remote handsets, slim calculators, kitchen scales, digital thermometers and small wearables. Always read the code off the cell you are removing before ordering a replacement.

How many cells do I actually receive?

Each pack contains six cells, and the minimum order is ten packs in multiples of ten, so the smallest order brings sixty cells.

How long will spares keep before I use them?

The pack states the cells are ready to use up to 10 years in storage, which is why buying a few ahead is sensible.

Which way round does the cell go in?

The printed, flat face is the positive side and faces the plus marking in the holder, with the plain side against the spring contact.

Is the packaging child resistant?

Yes. The blister is marked child resistant and needs scissors to open, and loose coin cells should always be kept away from small children.
