Button battery, also called button battery, is a battery whose trait size is like a small button, generally speaking the diameter of the button battery is larger than the thickness. From the shape of the battery to divide, can be divided into columnar batteries, button batteries, square batteries, shaped batteries, etc.. Coin cell batteries generally have 3v and 1.5v, mostly used in various IC motherboards and electronic products, etc. 3v batteries are CR927, CR1216, CR1225, CR1620, CR1632, 2032, etc.; and 1.5v batteries are AG13, AG10, AG4, etc.. Coin cell batteries are also divided into primary coin cell batteries and secondary rechargeable coin cell batteries, and the difference lies in whether the secondary rechargeable use. Share some general knowledge and skills on the use of coin cell batteries.、

Common sense and skills on the use of button batteries

1. CR2032 and CR2025 difference CR-type button batteries are the numbers behind the specific meaning in, such as CR2032 battery, 20 indicates that the diameter of the battery is 20mm, 32 represents the height of the battery is 3.2mm, the general CR2032 rated capacity of 200-230mAh ranging, CR2025
2. Button battery storage time and skills button battery can be stored for how long or mainly with the brand, that is, the quality of the battery itself, ordinary may be stored for six months are problematic, the general quality of better phones can be stored for 5 years, the capacity guarantee rate can reach 80% or more. In terms of storage to do away with light, in the dark, low temperature, airtight storage conditions.
3. If the 3V button battery dragging 3V LED lights, how long can drag it here are several decisive factors, first of all, the power consumption of the product itself, low power consumption, the battery dragging time is longer, and then the size or capacity of the battery, large capacity, the light can be more light time, generally Normal specifications can be used continuously for seven or eight hours no problem, of course, in the LED lights add a current limiting resistor can also increase the light time.
4. With a capacity of 220mA 3v button battery to do infrared remote control, continuous emission can generally be used for how long? Can use 1 month? Normally, if you don’t control it and keep firing, it’s hard to use one day. The general infrared remote control current value of 5-15mA, you can calculate the capacity. A month 30 days, if you use 30mAH every day, the working current control at 1mA can be used for a month. Or use the launch 0.1s stop 0.4s intermittent way, you can also use a month.
