Description
This is a single CR2 lithium cell from Duracell, supplied in the manufacturer's own blister pack. It gives 3V, and the pack also prints the code CR15H270, which is the longer designation some device manuals and battery drawers use for the same cell. The cell is a short cylinder with the positive end marked by a plus symbol. Lithium primary cells of this type hold their voltage firmly through most of their working life rather than sagging slowly, which is why equipment that draws hard in short bursts, such as a camera flash or a laser module, is usually specified around them.
CR2 cells turn up most often in compact film and instant cameras, in laser rangefinders used for golf and surveying, and in the sensors, keypads and locks fitted to alarm and door entry systems. A number of medical and measuring instruments use them too, wherever a compact three volt supply is wanted. If you are replacing a cell, read the marking on the one you take out before you order: CR2 and CR123 sound close but are different sizes, and a holder made for one will not take the other. The pack carries a keep out of reach of children warning, which is worth respecting with any loose cell.
One unit of this listing is one cell. Our minimum order is 10, sold in multiples of 10, so the smallest purchase brings 10 individual blister packs, which suits a camera club, a facilities cupboard or a counter display better than a one off swap at home. Duracell prints no shelf life figure on this pack, so we quote none. Loose cells are best left sealed in their blisters until needed and kept away from coins and keys. This cell sits alongside our wider range of Duracell batteries, including CR123 lithium cells, CR2032 and CR1620 lithium coin cells, and LR44 alkaline cells.

Frequently Asked
Is CR15H270 the same cell as a CR2?
Yes. The retail pack prints CR2 as the size and CR15H270 as the code, so a device asking for either name is asking for this cell.
How many cells do I receive?
One unit of this listing is a single cell in its own blister. The minimum order is 10 units, so the smallest order brings 10 cells.
Can I use a CR2 where a CR123 is specified?
No. Despite the similar naming they are physically different cells, and a battery compartment built for one will not hold the other properly.
Is this cell rechargeable?
Nothing on the pack marks it as rechargeable, so treat it as single use and never put it in a charger meant for rechargeable cells.
Does the pack state a shelf life?
No shelf life figure is printed on this pack, so we quote none. Keep the cells sealed in their blisters at normal room temperature.
How does lithium chemistry behave in the cold?
Lithium cells of this kind are known for holding their output in low temperatures better than ordinary alkaline cells, which matters for outdoor kit.
