Introduction | About button batteries: Button batteries are small in size, ranging from 4.8mm to 30mm in diameter and 1.0mm to 7.7mm in thickness; they are generally used as backup power supplies for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, and memory cards. , Remote control, electric toys, etc.; 1. Silver oxide battery: It is the most commonly used watch battery, most of the watches use silver oxide battery. The voltage of a new battery is generally between 1.55V and 1.58V, and the battery''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s shelf life is 3 years. The running time is generally not less than two years when used on a well-functioning watch. (1)Silver oxide batteries have two series: “SR××” and “SR××SW”. (2)The difference is that the silver oxide content in the battery is different: “SR××”series contain low silver content,“SR××SW”series contain The amount of silver is very high. (3) In terms of battery performance, the main difference is that the time on the 1.5V discharge platform is significantly different. The “SR××”series platform has a short discharge time; and the “SR& The times;×SW” series platform has a long discharge time, and about 90% of its life span is above 1.5V platform. 2. Lithium battery: 3V lithium button batteries are mostly used in anti-theft devices, access control, etc. Some watches are also equipped with lithium batteries.
