What kind of battery is AG30
AG30 is a button cell, also known as a button cell.
Generally speaking, there are two types of button batteries, rechargeable and non-rechargeable. The rechargeable ones include 3.6V rechargeable lithium-ion button batteries (LIR series), 3V rechargeable lithium-ion button batteries (ML or VL series); no Charging includes 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 AG3, AG30, AG33 batteries used in toys and gifts, batteries on computer motherboards, the model is CR2032 used in CR2025 in electronic dictionaries, CR2016 or SR44, SR626 used in electronic watches, etc.;
Extended information:
silver oxide
The button battery has the characteristics of long service life and large capacity, and is widely used, and its application volume is the largest. This kind of battery uses silver oxide as the positive electrode, metal zinc powder as the negative electrode, and the electrolyte is potassium hydroxide or sodium hydroxide. Electricity is generated through the chemical action of zinc and silver oxide.
The thickness (height) of the silver oxide button battery has five specifications of 5.4mm, 4.2mm, 3.6mm, 2.6mm, and 2.1mm, and its diameter has four specifications of 11.6mm, 9.5mm, 7.9mm, and 6.8mm. When choosing, one of them should be selected according to the size of its position. The commonly used models are AG3, AG2, AG3, AG3O, AG33, SR626, etc. The model AG is the Japanese standard, and the SR is the international standard model.
