CR1225 battery

What does CR1225 stand for?

The "C" in CR1225 represents the chemical composition, lithium is the negative electrode, manganese is the positive electrode, and organic matter is the electrolyte.

The letter R indicates the shape of the battery (here is Round)

The first two digits indicate the diameter of the battery in millimeters (12mm here)

The last two digits indicate the thickness of the battery (2.5mm here)

It is easy to judge the positive and negative poles of this battery. The rough end is the negative pole, and the opposite flat side is the positive pole, which is marked as "+" on the battery.


What is the difference between BR1225 and CR1225?

Answer: BR1225 is exactly the same as CR1225, it can be used instead. They all have the same voltage and capacity, basically not much difference. However, the chemical composition of BR1225 and CR1225 is slightly different, and BR1225 uses carbon monofluoride as the negative electrode.

Both batteries can be used in low-drain applications at room temperature, but CR1225 batteries are more suitable for high-drain applications (such as watches with LED lights and alarms) and BR1225 batteries are the best choice for high-temperature applications.

What are the safety issues of CR1225 batteries?

It can be ingested by pets and small children and can cause internal damage due to chemical spills.

These are non-rechargeable batteries. It may explode if forcibly charged.

Are CR1225 and CR1220 common?

A: Although CR1225 and CR1220 are similar, they are not completely universal.

CR1225 and CR1220 are two different battery models that vary in size and voltage. Among them, the diameter of CR1225 is 12.5 mm, the thickness is 2.5 mm, and the voltage is 3 volts, while the diameter of CR1220 is 12.5 mm, the thickness is 2.0 mm, and the voltage is also 3 volts. Therefore, they differ in size and capacity and cannot be used directly as substitutes.

Therefore, if you need to replace the battery, it is recommended to carefully check the device or product manual and determine the required battery model, so as not to choose the wrong battery.
