cr2016 and cr2032 are not universal.
The differences between the two:
1. Different thicknesses fit different battery slots. The thickness of CR2016 battery is 1.6mm. The thickness of CR2032 battery is 2.5mm.
2. Different capacities to adapt to different battery capacity requirements of electronic products. The nominal capacity of this cr2016 battery is 75mAh. The rated capacity of CR2032 battery ranges from 200 to 240 mAh.
Several common button cell models:
1. CR Button Cell Battery Models: Commonly used ones are CR2016, CR2032, CR2025, where CR stands for lithium ion cell. For manganese oxide batteries, the last four digits indicate the size. For example, CR2032 refers to a 3V button cell battery with a diameter of 20mm and a height of 3.2mm.
2. AG Series Button Cell Battery Model: The AG Commun Batterycommonly called in China is essentially a zinc-manganese alkaline battery. It is divided into 14 product series from AG0 to AG13, but it is always alkaline in the model. IEC standard. The battery labeling method is marked with the letters "LR", where L means alkaline and R means round.
3. Silver Zinc Oxide Battery: The size of the silver oxide battery can be the same as the zinc manganese alkaline button battery, but the voltage platform of the battery is different. The silver zinc oxide is relatively higher and the operating voltage is higher, its naming method is basically the same as that of the LR series. For example, “SR44” stands for silver zinc oxide battery, which is the size of LR44 and AG13.
Common rechargeable and non-rechargeable batteries include 3.6V rechargeable lithium-ion button cell (LIR series) and 3V rechargeable lithium-ion button cell ( ML or V seriesL). Non-rechargeable batteries include 3V lithium manganese button cells (CR series) and 1.5V alkaline zinc manganese button cells (LR series and SR series).
The code for button batteries generally has an R followed by a number. These numbers directly represent the diameter and thickness of the battery, such as CR3032 lithium button, which refers to a diameter of 30mm and a thickness of 32mm. Some special diameter and thickness codes, such as LR41, refer to an alkaline battery, a. A diameter of 7.9mm and a thickness of 3.6mm, SR43 refers to the silver oxide battery, 11.6mm in diameter and 4.2mm in thickness.
Here are some common button batteries:
Detailed information:
Classification of button batteries
1. Lithium battery
Ordinary disposable lithium batteries are lithium manganese batteries (C code) with a rated voltage of 3V.
A less common type of disposable lithium battery is the fluorocarbon lithium battery (Code B), its nominal voltage is 3v.
In addition, common secondary lithium batteries include ML lithium batteries (code name ML), with a rated voltage of 3V.
The size number of batteries lithium generally adopts the new IEC numbering method. The first two numbers are the diameter (mm) and the last two numbers are the thickness (0.1mm), which are very close to each other. .
2. Silver oxide
The present invention has the characteristics of long life and large capacity. The battery uses silver oxide as the positive electrode, zinc metal powder as the negative electrode, and potassium hydroxide or sodium hydroxide as the electrolyte. Electricity is produced by the chemical reaction of zinc and silver oxide.
The thickness (height) of the piThe silver oxide button is 5.4mm, 4.2mm, 3.6mm, 2.6mm and 2.1mm, and its diameter is 11.6mm and 9.5mm , 7.9mm, 6.8mm. four specifications.
You must choose one based on the size of its location. Commonly used models include AG1, AG2, AG3, AG1O, AG13, SR626, etc. AG is a Japanese standard and SR is an international standard.
3. Silver peroxide
The structure of the battery is basically the same as that of the silver oxide button cell. The main difference is that the anode (anode) of the battery is made of silver peroxide.
4. Alkaline manganese
This battery has the advantages of large capacity, good low temperature performance, cheap materials and low price, and can meet the requirements of continuous current discharge important. .
The disadvantage is that the energy density is not sufficient and the discharge voltage is not stable enough. The anode ofalkaline manganese button battery is manganese dioxide, the cathode is zinc, the electrolyte is potassium hydroxide, and the rated voltage is 1.5V.
5. Mercury
Also known as mercury battery, it can be used under high temperature conditions, stored for a long time, has stable discharge voltage and good mechanical properties. However, its low temperature characteristics are not good. The battery has a positive value for mercury and a negative value for zinc. The electrolyte may be potassium hydroxide or sodium hydroxide. Its nominal voltage is 1.35V.
6. Lithium-ion
The rated voltage of the disposable lithium manganese coin cell battery is 3V, the termination voltage is 2V, and the typical operating current is 0.1-0.2mA . It uses manganese dioxide with very stable chemical properties as the positive electrode material.ive and metallic lithium with very high specific energy as negative electrode material.
The average annual reduction in capacity does not exceed 2% and the storage life is long. The battery adopts a semi-sealed structure and is safe to use. Disposable lithium manganese button batteries have a wide temperature adaptability range and can work normally from -20 to +60 degrees Celsius.
