Information

With the popularity of smart TVs and network set-top boxes, Shenzhen Liyuan and everyone will find that the remote control is also ultra-thin and compact. The battery inside has changed from the previous No. 5 or No. 7 battery to a 3V button battery. Careful observation shows that there are some types of batteries, such as CR2025 and CR2032. The CMOS battery on the desktop board is also one of these two models.

At first, it seems that the difference between the two kinds of button batteries commonly used. The rated voltages of the two batteries CR2032 and CR2025 are the same and all are 3V. The difference is the battery specifications and capacity. The capacity of CR2032 is 210 mAh, the capacity of CR2025 is 150 mAh, the thickness of CR2032 is 3.2 mm, and the thickness of CR2025 is 2.5 mm.

Take CR2025 as an example to explain the meaning of the battery model code. c represents a chemical battery with lithium metal as the negative electrode and manganese dioxide as the positive electrode. r represents the cylindrical shape of the battery. The first two digits 20 represent a battery with a diameter of 20 mm, and the second two digits 25 represent a battery with a thickness of 2.5 mm.

In addition to the two batteries commonly used in smart TVs and network set-top boxes, these batteries are also used for Bluetooth access control of many batteries. In general, two batteries can be substituted if the volume allows. There are also button batteries.

For this type of button rechargeable batteries, most of them are 1.6 thick and too thick. There are many types of model codes that are inconsistent. You can check the corresponding size and capacity of different models. LR and AG series button batteries are 1.5V button alkaline manganese batteries.

In addition to RV series rechargeable batteries and AG series rechargeable batteries, there are also LIR series rechargeable batteries. The first two digits of the battery code LR represents a 1.5V mercury rated voltage, SR represents a 1.55V mercury voltage, CR represents a 3V lithium voltage, ZA represents a 1.4V zinc air voltage, and LIR represents a 3.7V secondary lithium voltage (ie rechargeable battery).

In this way, if you understand the above knowledge and see a similar button cell, you can know its meaning. How to choose and replace it is no longer difficult. Did this short science article increase knowledge?

How to choose the right primary lithium battery
It is a new type of high-energy battery, which has the advantages of large specific energy, high voltage, wide operating temperature range, long storage life, environmental protection and no pollution. However, any type of battery must be suitable for the conditions of use of electrical appliances. Liyuan Battery Editor will make some explanations on the technical issues that need to be considered when selecting a lithium battery for customers to refer to when choosing a battery.
