Duracell CR2430 3V Lithium Coin Battery

The CR2430 is one of the larger lithium coin cells, and the code rather than the look of it is what you match on. In the IEC naming system the figures are the measurement: 2430 means a 24mm diameter and a 3.0mm height, so this cell will not seat properly in a holder built for a 2032 or a 2450, even though all three look alike in the hand. This is a 3V lithium cell from Duracell, supplied as one cell in a child resistant blister pack, carrying the code DL/CR2430.

Coin cells this size turn up in car key fobs and alarm remotes, garage door openers, digital thermometers, kitchen timers and scales, calculators, small medical monitors and the miniature LED lights used in models and decorations. The surest way to buy the right one is to take the old cell out of its holder and read the code printed on its face, since few manuals name the size. If it reads 2430 or DL2430, this is the same cell. Make a note of which way it sat before you lift it out: the marked face is the positive side, and on most holders it faces upward.

You receive one cell per pack. The blister is a child safety pack and needs scissors to open, which is deliberate: coin cells are a swallowing hazard and should be kept away from small children, and the same goes for the spent cell once it is out. The minimum order on this listing is 10 units, sold in multiples of 10, which suits a workshop, a maintenance store or anyone who would rather not chase a 2430 at short notice. Lithium holds its charge in storage better than alkaline chemistry does, so spares are worth keeping. We stock the same Duracell coin cells in CR1616, CR1620, CR2016, CR2025, CR2032 and CR2450, along with LR44 alkaline and silver oxide watch cells.

How many cells do I actually receive?

One cell per pack. The minimum order is 10 units, so the smallest order gives you 10 separate single cell packs.

Is a CR2430 interchangeable with a CR2032 or a CR2450?

No. All three are 3V lithium coin cells, but the diameters and heights differ, so a 2430 will not sit correctly in a holder made for either of the others.

What does the DL/CR2430 code on the pack mean?

DL is the older Duracell prefix and CR is the international prefix for a 3V lithium coin cell. Both codes name the same cell, so either marking on your old battery matches this one.

Which way round does the cell go in?

The flat face carrying the printed code is the positive terminal. In most holders it faces upward or outward, but note the orientation before removing the old cell.

Does the manufacturer state a shelf life for this cell?

The retail pack prints no shelf life figure for the CR2430, so we do not quote one. Store cells at room temperature in their sealed blister until needed.

Why does the blister need scissors to open?

It is a child safety pack. Coin cells of this size are a serious swallowing hazard, so the packaging is built to resist small hands rather than to tear open easily.
