what is a cr2032 battery
cr2032 battery Is a kind of 3V button lithium ion battery, is also one of the most widely used button type battery, because of its high energy, can be stored for a long time, safety is very high, this is the main reason why it is popular, its working principle is such, cr2032 battery is a kind of lithium battery, positive is composed of lithium alloy material and conductive agent, negative adopts carbon materials, and diaphragm use microporous polyolefin membrane, diaphragm separated them, usually inside a one-way chemical reaction, positive to negative electron release. Unnormal circumstances, the situation may be completely different, current may flow in the opposite direction, its name is also follow the IEC standard system, including "CR" with lithium metal as the anode, with manganese dioxide as positive chemical battery system, "20" said the diameter of the battery of 20 mm, "32" represents the battery of the height of 3.2mm.
cr2032 voltage range
cr2032 lithium 3v coin battery,, cr2032 battery voltage in most cases in the appearance of the product and packaging logo, well-known 3V, open circuit voltage is about 3.6volts, the capacity of cr2032 battery is about 200 mAh , this will change because of the size of the current, CR2032 battery in abnormal charging conditions, can withstand the maximum current is 5 mA.

cr2032 dimensions
Listed here are the specification, sizes, attributes, and parameters of the CR2032. size. Diameter：20 mm. Height：3.2mm. In fact, different brands are the same.
how long do cr2032 batteries last
cr2032 battery Life is usually in 4-10 years, it mainly depends on how you are to apply it, different application methods will determine its life length, constant current for 1 micro Ann or lower applications, battery life up to 10 years, of course, low power products may not necessarily can guarantee the life of CR2032, still need to rely on smart designers, how to power consumption smart application in the function of the product.
what uses cr2032 battery

| small equipment | Watches, calculators, electronic car keys, remote control, LED lights, toys, alarm clock |
| supply of power supply to keep the equipment running; | Vending machines and vending machines: |
| armamentarium | Heart rate monitor, sphygmomanometer, stethoscope, blood glucose meter |
| sports equipment | Such as sports watch, pedometer, heart rate belt, etc.; |
| Internet of Things devices | Such as sensors, smart home devices, security systems, etc. |
cr2032 how to charge it up
CR2032 Usually can not be charged, the invention of this battery is not intended to charge, because of its cheap and convenience in most cases will choose to be directly replaced, if you do need to charge, it is not impossible, need to have a special way to operate.
what is the difference between cr2032 and cr2025
| cr2032 | cr2025 | ||
Thickness is thicker | 3.2 mm | Thickness is thinner | 2.5mm |
The current is higher | 225mAh | The current is lower | 160mAh |

What you need to know here is that button batteries can be divided into rechargeable and non-rechargeable batteries. The types of charging are 3.6 VLIR series and 3 VML series, LV series. Non-rechargeable type batteries include 3 VCR series, 1.5 VLR series, and 1.55 VSR series.Bearing a discharge current of 10 mA.
how to test cr2032 battery
Generally we detect CR2032 use is universal table, it can help you test whether your battery power is weak or no short circuit problem, for example: if 3V CR2032 battery power weak, the use it electricity light may not be so much, or only bright half, this is also intuitive can test method, but universal table can do more detail.
We can use a universal meter to test a 3V voltage battery. If the test voltage is 3.3V, it means that the battery is very new, and if it is below 2.7V, it means that the battery is running out. Use a multimeter to measure the battery voltage.
how much is a cr2032 battery
cr2032 battery The price gap between different brands is relatively large, of course, you have reason to believe that the quality of different price batteries is not only the same, usually the price is: 0. [] 3-0. [] $8 or so.
how to install cr2032 battery
Usually purchased CR2032 with installation instructions, can be found Step-by-StepBattery ReplacementInstructions，Usually, you need to first locate the CR2032 slot on the system board and use a screw in gesture to naturally insert the CR2032 into place.
In the process of most Coin battery application, we can judge the quality of the battery through the reaction of electronic devices. If it can be tested with a multimeter, then we can know the situation of the battery more closely.Then the multimeter to detect CR2032 can follow the following steps：
1: First prepare the Coin battery you need to detect, and then find its voltage value, the voltage of CR2032 is 3V.
2: Set the voltage of the instrument to the DC voltage gear.
3:
Put the black pen vertically against the center of the battery. Remember that this side is the side of the battery mark.
4:
Place the red pen on the side of the battery.
5: Watch the voltage change on the meter, as shown in the figure if the detected voltage is 3.3V, then the battery is still relatively new. This reference is based on the voltage of the cr2032 that we detected.
6: If the test result is 2.6V, that means that our battery level is relatively weak. If it is 2V or 1.5V, your battery is already damaged. The lower the value, the worse the battery status.
