Description
The CR1225 is a lithium coin cell rated at 3V, and this listing supplies one cell. Its code describes it: under the IEC naming system, CR marks a lithium manganese dioxide coin, 12 gives a diameter of 12.5mm and 25 gives a height of 2.5mm, so a cell sold as CR1225 is the same size whoever makes it. Lithium chemistry is what gives coin cells their long, flat discharge: the voltage stays close to nominal for most of the working life rather than tailing away early.
Coin cells of this diameter are chosen where there is no room for a cylindrical battery, so the CR1225 usually sits in slim, low drain electronics. The safest way to buy a replacement is to read the code off the cell already in the device, or off the battery compartment door, and match it exactly. A CR1225 will not stand in for a CR2032 or a CR1620: all three are 3V lithium coins, but the diameter and the thickness differ and the contacts will not meet properly.
One cell arrives on a child resistant card that needs scissors to open, which is worth knowing before you go hunting for a fingernail edge. Ordering is in tens: the minimum order is ten units of this listing, sold in multiples of ten, so one order brings ten individual cells rather than one. That suits a workshop, a maintenance box, or anyone keeping spares for several devices. We stock other Energizer cells alongside this one, including CR2032 and CR1620 lithium coins, SR626 silver oxide coins and CR123 lithium cells.

Frequently Asked
How do I know my device takes a CR1225?
Read the code moulded onto the face of the spent cell, or printed inside the battery compartment. It has to read CR1225 to match.
Is a CR1225 the same as a CR1220 or a CR1216?
No. The first two digits give the diameter and the last two the height, so those cells share the 12.5mm width but are thinner than this one.
How many cells do I actually receive?
One cell per unit. Because the minimum order is ten units in multiples of ten, a first order brings you ten separate single cells.
What voltage does it give?
The pack states 3V. That is the nominal figure for a lithium coin cell, and it holds close to it for most of its working life.
Can I open the pack by hand?
Not easily. The card is a child resistant type and the pack shows scissors, so keep a pair to hand when you come to fit the cell.
Does the manufacturer state a capacity in mAh?
No capacity figure is given in the information supplied with this cell, so we quote none. The size, chemistry and voltage are what you match on.
