Panasonic Lithium Coin Cell Batteries (CR2032) - 6 Pack

This is a card of six Panasonic CR2032 lithium coin cells, each one rated at 3V as printed on the pack. CR2032 is an international code rather than a brand name, so it describes the cell itself: the numbers are its size in millimetres, 20mm across and 3.2mm deep. That means you only need to match the code stamped on the old cell, or printed inside the battery compartment, and the replacement will drop straight in. Every cell on this card carries the CR2032 marking on its face.

Coin cells this size turn up in more places around the house than most people expect. Car key fobs and alarm remotes are the obvious ones, along with watches, kitchen scales, digital thermometers, key finders, flameless candles, glucose meters and the small backup cell on a computer motherboard that keeps the clock and the settings alive. Because they all call for the same code, a card of six is worth keeping in a drawer rather than hunting for a single cell the evening something goes quiet. The pack front shows watch and car key symbols for exactly that reason.

The card is printed as child safety packaging, and that matters: coin cells are small enough to be swallowed, so keep both new and spent cells away from young children and pets, and get medical help straight away if one is swallowed. The pack is also marked 0% Hg added, meaning no mercury is added to the chemistry. Store the card somewhere cool and dry, leave each cell in its blister until the moment you need it, and never let loose cells rattle around with coins or keys. Spent cells belong at a battery recycling point rather than in the household bin.

How many cells do I actually receive?

One card holding six CR2032 cells, all on a single blister. The cards themselves are sold in multiples of twenty, so the smallest order is twenty cards.

What voltage are these, and how do I check my device takes a CR2032?

Each cell is 3V, as printed on the pack and on the face of the cell. Look at the code on the old cell or inside the empty compartment; if it reads CR2032 these will fit.

Can CR2032 cells be recharged?

No. Nothing on this pack describes them as rechargeable, and cells of this type are primary cells meant for single use. Never put one in a charger.

How should I store spare coin cells?

Somewhere cool and dry, with each cell left sealed in its blister until you need it. Loose cells stored against coins, keys or other cells can short against each other.

What should I know about keeping these away from children?

The card is child safety packaging, printed as such on the front. A swallowed coin cell is a medical emergency, so store new and spent cells out of reach and seek help immediately if one is swallowed.
