Button batteries, also known as button batteries, refer to batteries that resemble a small button in size. Generally speaking, the diameter of a button battery is larger than its thickness. From the perspective of appearance, batteries can be divided into cylindrical batteries, button batteries, square batteries, and special-shaped batteries. Button batteries are generally available in 3V and 1.5V versions and are commonly used in various IC motherboards and electronic products. The 3V batteries are CR927, CR1216, CR1225, CR1620, CR16322032, etc; And 1.5V batteries are AG13, AG10, AG4, and so on. The button cell is also divided into a primary button cell and a secondary charging button cell. The difference lies in whether it can be used for secondary charging. Share some common sense and tips on using button batteries.

Common Sense and Techniques for Using Button Batteries
1. The difference between CR2032 and CR2025 The numbers behind the CR button battery have specific meanings. For example, CR2032 battery, 20 indicates the diameter of the battery is 20mm, 32 indicates the height of the battery is 3.2mm, generally the Nameplate capacity of CR2032 is 200-230mAh, and the Nameplate capacity of CR2025 is 140-170mAh.
2. The storage time and skills of button batteries mainly depend on the brand, which is the quality of the battery itself. Ordinary batteries may have problems with storage for half a year, while better quality phones can be stored for 5 years, with a capacity guarantee rate of over 80%. In terms of storage, it is necessary to avoid light and store in dark, low temperature, and enclosed conditions.
3. If you use a 3V button battery to drag a 3V LED small light, how long can it be dragged? There are several decisive factors here. Firstly, the power consumption of the product itself is low, and the battery drag time is longer. Secondly, the size or capacity of the battery. If the capacity is large, the light can be lit for more time. Generally, normal specifications can be used continuously for seven to eight hours without any problem. Of course, Adding a current limiting resistor to an LED light can also increase the time it stays on.
4. How long can a 3V button battery with a capacity of 220mA be used for infrared remote control and continuous transmission? Can it last for one month? Normally, if it is not controlled and continues to launch, it is estimated that it will be difficult to use it for a day. The current value of a typical infrared remote control is 5-15mA, so you can calculate the capacity. For 30 days a month, if you use 30mAH every day and control the working current at 1mA, you can use it for one month. Alternatively, the intermittent mode of firing for 0.1 seconds and stopping for 0.4 seconds can be used, or it can be used for one month.
