Duracell CR1616 3V Lithium Coin Battery

This is a single Duracell CR1616 lithium coin cell, rated at 3V and supplied one cell to a blister card. The pack prints the code as DL/CR1616: the same cell under two naming systems, DL being Duracell's own prefix and CR the international code for a lithium coin. The four digits are a size code rather than a model number, so any cell marked 1616 is the same physical size whoever makes it. Lithium chemistry is what suits this format to small electronics, holding a steady 3V for most of its working life rather than fading slowly, so a watch keeps time and a key fob keeps its range until the cell is genuinely spent.

Coin cells of this size turn up in watches, car key fobs, calculators, digital thermometers, small remote controls and the backup cells inside some electronics. The surest way to buy the right one is to read the marking on the cell you are taking out rather than the model number of the device, because makers change cell sizes between revisions of the same product. If the old cell reads CR1616, DL1616 or 1616, this is a direct match.

Each unit is one cell on a child-resistant blister that the pack calls a Baby Secure pack, so you will need scissors to open it, and the card carries a keep out of reach of children warning. Swallowed coin cells are a medical emergency, so it is worth leaving spares sealed in the card until the moment you need them. The listing is sold as a single cell with a minimum order of 10 units, in multiples of 10, which suits anyone keeping a small stock behind the counter or in a toolbox. We also stock Duracell lithium coin cells in CR1620, CR2016, CR2025 and CR2032.

How do I know my device takes a CR1616?

Take out the old cell and read the face of it. Coin cells are marked with their own size code, and that marking is more reliable than any figure printed in the device manual.

Is DL1616 the same cell as CR1616?

Yes. The pack itself prints both, as DL/CR1616. DL is the manufacturer's own prefix and CR is the international designation for a lithium coin cell of that size.

Can I fit a CR1620 or a CR2016 instead?

No. Those digits describe a different physical size, so the cell will either sit loose in the holder or refuse to seat at all. Match the four digits exactly.

How many cells do I actually receive?

One cell per unit of this listing. The minimum order is 10 units in multiples of 10, so the smallest order brings you 10 individually carded cells.

Why does the blister need scissors to open?

The card is a child-resistant Baby Secure pack, so it cannot be torn open by hand. Cut along the guide on the card and keep the loose cell away from children.
