Duracell 1/3N 3V Lithium Coin Battery (CR1/3N)

Duracell's 1/3N is a single lithium coin cell rated at a nominal 3 volts, and it arrives as one cell on a blister card. It answers to more than one name: the pack prints the codes 2L76, CR1/3N and CR11108, while the same cell is catalogued as DL1/3N. If one of those is printed on the cell you are taking out, or quoted in your device manual, this is the part you want. Lithium chemistry gives 3 volts from a single cell, where an alkaline or silver oxide button gives around 1.5 volts, so matching the size alone is not enough.

This is a specialist size rather than a household one, so it is worth checking exactly what your equipment asks for before you order. Codes vary between manufacturers for the same cell, and a manual will often quote only one of them, so read every marking on the old cell before matching it up. Because this is not a size most shops keep on the shelf, a spare in the drawer saves a hunt later. We stock it alongside other Duracell specialist cells, including CR2032, CR2025, CR2016, CR1620 and CR1616 lithium coin cells, LR44 alkaline, the N size LR1, and 364, 371 and 376 silver oxide watch cells.

The retail pack claims 50 per cent more power, and the small print qualifies it: the comparison is against the IEC standard test minimum average duration for the CR11108 size, with results varying by device and usage. No shelf life figure is printed on the pack, so we do not quote one. The card also carries a keep out of reach of children warning, which is worth taking seriously with any coin cell: they are small enough to swallow and belong well away from children before and after use. One cell is what you receive per unit, and the minimum order is 10, sold in multiples of 10.

How do I know this is the right cell for my device?

Read the markings on the cell you are removing, or the code quoted in the device manual, and look for 1/3N, 2L76, CR1/3N, CR11108 or DL1/3N. Any one of those names this cell.

Is a CR1/3N the same thing as a 2L76 or a CR11108?

Yes. Those are different manufacturers' codes for one cell, and the pack prints all three together, so you can order against whichever code your equipment happens to quote.

Can this cell be recharged?

No. Nothing on the pack describes it as rechargeable, and primary lithium coin cells are made to be used once and then recycled rather than put on a charger.

How many cells do I get, and why is there a minimum order?

One cell per unit. This line is bought in trade quantities, so the minimum order is 10 units, sold in multiples of 10, which suits a workshop or service counter holding stock.

What does the 50 per cent more power line on the pack mean?

It is Duracell's own comparison against the IEC standard test minimum average duration for the CR11108 size. The pack adds that results vary by device and by how the cell is used.
