Generally speaking, there are two types of button batteries, rechargeable and non-rechargeable.

Button battery model diagram
, Charged include 3.6V rechargeable lithium-ion button battery (LIR series), 3V rechargeable lithium-ion button battery (ML or VL series); non-rechargeable include 3V lithium manganese button battery (CR series) and 1.5V Alkaline zinc manganese button batteries (LR and SR series);
The more common button batteries are AG3, AG10, AG13 batteries used in toys and gifts, batteries on computer motherboards, model CR2032 used in CR2025 in electronic dictionaries, CR2016 or SR44, SR626 on electronic watches, etc.;
The English letters in front of the model name of the button battery indicate the type of battery, the number indicates the size, the first two numbers indicate the diameter, and the last two indicate the thickness;
Common typical models are: 6F22 (9V), 4F22 (6V), 15F20 (22.5V), 10A (9V), 11A (6V), 23A (12V), 2 (9V), 26A (6V), 27A (12 ), 476A (6V), 120H7D (8.4V), 2X62 (3V) and so on.

application
Because of its small size, button batteries have been widely used in various miniature electronic products, with diameters ranging from 4.8mm to 30mm and thicknesses ranging from 1.0mm to 7.7mm; they are generally used as backup power supplies for various electronic products, such as Computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, pacemakers, electronic hearing aids, counters, cameras, etc.
Button batteries are also divided into two categories: chemical batteries and physical batteries, and their chemical batteries are widely used. They are composed of positive (positive), negative (negative) and their electrolytes. As shown on the right. Its surface is made of stainless steel, and as the positive, its negative is a stainless steel circular cover, there is a sealing ring between the positive and negative for insulation, the sealing ring is made of nylon, the sealing ring not only acts as insulation, but also prevents the leakage of electrolyte . There are many types of button batteries, most of which are named after the materials used, such as silver oxide batteries, lithium batteries, alkaline manganese batteries, etc.
The corresponding markings can be seen from the back of the battery: [1]
LR---Alkaline--1.5V
SR---Silver Oxide--1.55V
CR---Lithium battery--3V
ZA---Zinc Air--1.4V
