Button battery, also called button cell, coin cell, refers to a battery with a small button shape, generally larger in diameter and thinner (compared to cylindrical batteries such as AA batteries on the market);

Button batteries are divided into batteries from the appearance. The same corresponding battery classification includes cylindrical batteries, pouch batteries, and special-shaped batteries;

Button batteries generally have two types: rechargeable and non-rechargeable. The rechargeable ones include 3.6V rechargeable lithium-ion button batteries (LIR series) and 3V rechargeable lithium-ion button batteries (ML or VL series); no Rechargeable batteries include 3V lithium manganese button batteries (CR series) and 1.5V alkaline zinc manganese button batteries (LR and SR series);

The more common button batteries are CMOS batteries used on computer motherboards, the model is CR2032 for CR2025 in electronic dictionaries, and CR2016 or SR44, SR626 for electronic watches, etc.;

The English letter in front of the button battery model name indicates the type of battery, the number indicates the size, the first two digits indicate the diameter, and the last two digits indicate the thickness;

Button batteries are small in size, ranging from 4.8mm to 30mm in diameter and 1.0mm to 7.7mm in thickness.

Because of its good temperature, good sealing performance, long storage time, stable discharge voltage and many other advantages. It is generally used as a backup power supply for various electronic products, such as computer motherboards, Mp3 watches, calculators, IC cards, electronic dictionaries, electronic scales, memory cards, remote controls, tax control machines, Bluetooth headsets, hand-cranked rechargeable flashlights, toy walkie-talkies And other products.
