Explore the world of button batteries

With the rapid development of technology, electronic products have become an indispensable part of our daily lives. What powers these electronic products are those small button-shaped batteries, which we usually call "button batteries."

Button batteries, although they vary in thickness and size, all share the name because they resemble buttons. These batteries are widely used in various electronic products, such as watches, calculators, remote controls, etc., bringing great convenience to our lives.

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

In the world of button batteries, they can also be divided into non-rechargeable batteries and rechargeable batteries from the perspective 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, etc.

The 3V lithium manganese battery (CR) series is widely used in various electronic products due to its high voltage and lightweight characteristics, especially equipment that requires higher voltage drive. 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 due to 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 lives and bring great convenience to our lives. And understanding their voltage classification can help us better select and use these small "power sources".
