Description

The Energizer CR1225 is a 3V lithium coin cell battery measuring 12.5mm diameter by 2.5mm thickness, designed for compact electronic devices including watches, calculators, key fobs, remote controls and medical devices such as glucose monitors. The lithium chemistry provides stable voltage output across the battery's service life and functions reliably in temperatures from -30°C to +60°C.

Used in devices requiring a flat, low-profile power source, the CR1225 fits battery compartments designed for 12.5mm coin cells. Common applications include wristwatches (both analogue and digital), car key fobs, LED tea lights, small remote controls, fitness trackers, and medical devices where consistent 3V output is needed. The battery is also compatible with devices specifying BR1225, DL1225, ECR1225, or equivalent 12.5mm lithium coin cells.

Energizer lithium coin cells use leak-resistant construction to protect the device and surrounding components from corrosion if the battery remains installed beyond its service life. The CR1225 chemistry delivers higher energy density than alkaline button cells of similar size, meaning longer run-time between replacements in devices with continuous low-drain operation such as watches and passive sensors. Shelf life extends up to 10 years when stored at room temperature in original packaging.

Frequently Asked

What devices use a CR1225 battery?

The CR1225 fits watches, calculators, car key fobs, small LED lights, fitness trackers, remote controls and medical devices such as glucose monitors. Check your device's battery compartment or manual for the specified cell size before purchasing.

What does CR1225 mean?

CR indicates lithium manganese dioxide chemistry. 12 refers to the 12.5mm diameter, and 25 refers to the 2.5mm thickness. This standardised naming helps identify compatible replacements across brands.

Can I use a BR1225 instead of a CR1225?

BR1225 batteries use lithium carbon monofluoride chemistry and are designed for lower current drain and wider temperature ranges than CR1225. In most consumer devices (watches, key fobs) the CR1225 is the correct choice. BR1225 is typically specified for industrial or automotive applications requiring operation below -30°C.

How long does a CR1225 last in a watch?

In a typical analogue quartz watch drawing 1-3 microamps, a CR1225 runs for approximately 2-4 years depending on additional functions (backlight, alarms, chronograph). Digital watches with continuous display and frequent backlight use will see shorter service life.
