Button battery is the shape of the button like a battery, it is actually a lithium battery. Lithium is the lightest metal, so lithium batteries are lightweight, durable, high stability, Button Cell the advantages of long-lasting power. More limited to precision instruments.
Button batteries are used for toys and gifts on the AG3, AG10, AG13 battery, the computer motherboard battery, model CR2032 for the electronic dictionary inside the CR2025, for the top of the electronic watch CR2016 or SR44, SR626;
Button battery is also very common battery, small, many models. Common button batteries are made of chemical composition such as carbon, alkaline, zinc-silver oxide, zinc-air, lithium-manganese dioxide, nickel-cadmium rechargeable button batteries, nickel-metal hydride rechargeable batteries. If the shape of the monomer and the layers of the distinction.
Button model name in front of the English letter that the battery type, the number that size, the first two digits that diameter, the latter two said thickness; common typical models are: 6F22 (9V), 4F22 (6V), 15F20 (22.5 (6V), 27A (12), 476A (6V), 120H7D (8.4V), 2X625A (3V), etc.
Coin batteries are generally available in both charging and non-charging, Button Cell including a 3.6V rechargeable lithium ion battery (LIR series), a 3V rechargeable lithium ion battery (ML or VL series), a charge and no charge Common batteries. Charging includes 3V lithium manganese button batteries (CR series) and 1.5V alkaline zinc manganese button batteries (LR and SR series);
Button battery model name in front of the English letter that the battery type, Button Cell the size of the first two digits of the diameter, the latter two said thickness;
Button batteries from small size, diameter from 4.8mm to 30mm, thickness from 1.0mm to 7.7mm range; generally used for computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory cards, remote control, electric toys and other electronic products ;
Button battery has a long life, large capacity and other characteristics, a wide range of applications, the most applications. Batteries from silver oxide as a positive electrode, Button Cell metal zinc powder as a negative electrode, the electrolyte is potassium hydroxide or sodium hydroxide. Through the chemical action of zinc and silver oxide. In the selection should be based on the size of its location, select one of them. Its common models are AG1, AG2, AG3, AG1O, AG13, SR626, etc., model AG for the Japanese standard, SR for the international standard models.
