With the rapid development of science and technology, electronic products have become an indispensable part of our daily life. The power for these electronic products is those small batteries shaped like buttons, which we usually call "button batteries."


Button batteries with different thickness and sizes, but the shape like button so they have a common name. These batteries are widely used in a variety of electronic products, such as watches, calculators, remote controls, and so on, which brings great convenience to our lives.

For these big and small button batteries, we usually classify them according to their nominal voltage. For example, the 3V button battery we often say refers to the CR series battery in most cases, and the 1.5V button battery usually refers to the AG series battery.


In the world of button batteries, it can also be divided into non-rechargeable batteries and rechargeable batteries from the point of view of voltage. Non-rechargeable button batteries mainly include 3V lithium manganese battery (CR) series, 1.5V alkaline button battery (LR series, including AG series), 1.55V Zinc-silver oxide battery button battery (SR) series.


3V lithium manganese battery (CR) series because of its high voltage and lightweight characteristics, widely used in all kinds of electronic products, especially the need for higher voltage drive equipment. The 1.5V alkaline button battery (LR series, including AG series) has become the best choice for many home appliances and office equipment because of its stable voltage and long working time. The 1.55V Zinc-silver oxide battery button battery (SR) series is gradually favored by the market because of its high energy density and environmental protection characteristics.


Button batteries are an indispensable part of our lives, they exist in various forms in our daily life, bringing great convenience to our lives. Understanding their voltage classification can help us better choose and use these small "power sources".
