Button cell (button cell), also known as button cell, refers to a battery whose shape is like a small button. Generally speaking, it has a larger diameter and thinner thickness (compared to cylindrical batteries such as AA batteries on the market). The lithium manganese button battery CR2032 is non-rechargeable and is also a chemical battery. They are composed of an anode (positive electrode), a cathode (negative electrode) and its electrolyte. As shown on the right. Its appearance is made of stainless steel material and serves as the positive electrode. The negative electrode is a stainless steel circular cover. There is a sealing ring between the positive electrode and the negative electrode for insulation. The sealing ring is made of nylon. The sealing ring can prevent electrolyte leakage in addition to insulation. . The nominal voltage of lithium manganese disposable button batteries 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, and lithium metal with very high specific energy as the negative electrode material. The annual average capacity reduction is not more than 2%, and the storage life is long. The battery adopts a semi-sealed structure and is safe to use. Lithium-manganese disposable button batteries have a large temperature adaptation range and can work normally under the conditions of -20 to +60 degrees Celsius. It is mostly used in electronic dictionaries, motherboard CMOS batteries, watches and so on.

[Test Method]
A: Test: Ambient temperature: 20~25ºC Ambient humidity: 65±20%.
B: Charge with constant current 0.2mA, charge to ≥3.1 V, switch to constant voltage charge for 60 minutes; use 0.4mA Discharge to 2.0 V.

Instructions for use and precautions:
Do not hold the positive and negative poles of the battery at the same time


You should hold the edge of the battery with your fingers


Prohibition of stacking may cause short-circuit of the battery, which may cause safety hazards!

 

•  The positive and negative electrode covers of the battery are silver-plated, and the silver oxide battery can run healthy and provide long-term stable voltage.
•  The production process does not add harmful substances such as aluminum, chromium, mercury, etc., and is safe and pollution-free.
•  The appearance is Stainless steel material, good sealing performance, effectively prevent short circuit and leakage between the positive and negative electrodes of the battery, improve battery safety.
•  Low self-discharge, can be stored for 5 years, it is recommended to store in a low temperature and dry environment to relatively extend the battery storage time.
 

It is generally used as a backup power supply for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, cardiac pacemakers, electronic hearing aids, counters, cameras, etc.
