Have you ever excitedly bought a new smart device, such as a cool key tracker, a sophisticated thermometer, or a stylish desktop clock, only to be stunned when installing the batteries? Looking at the small battery compartment in my hand, and then at the dazzling array of batteries on the shelf, a series of questions popped into my head: Should I use the one that looks like a small button, or the flat cylindrical one usually called "CR2032"? They seem pretty much the same? Should I just buy any one that works? Hold on! This choice is far more important than you think. Choosing the wrong battery can lead to anything from poor device performance and reduced battery life to potentially damaging your beloved devices. Today, this practical guide will thoroughly clarify the differences between lithium manganese batteries (represented by CR2032) and the broad family of button batteries, helping you overcome your choice paralysis and become a "power expert" among your friends!

With smart devices ubiquitous today, making IoT devices more power-efficient and longer-lasting has become a challenge every engineer must face. The rapid development of the Internet of Things (IoT) has connected billions of devices to the internet, many of which rely on disposable batteries for years or even decades. In these applications, lithium-manganese button batteries have become the preferred power source due to their compact size, stable voltage, and long life.

5G IoT devices widely use button batteries, mainly due to their following advantages: Small and compact: IoT devices are becoming increasingly miniaturized, and button batteries are well suited to this demanding space requirement. High energy density: Especially in chemical systems such as lithium-manganese button batteries (such as CR2032), it can provide high energy in a small volume, meeting the long-term battery life requirements of IoT devices.

Button batteries have always been the optimal solution for the wearable devices due to their maturity and size advantages. The button batteries produced by Power Glory play an important role in wearable devices (such as smart watches, health monitoring devices, wireless headphones, etc.), especially in the quest for lightweight designs and long battery life.
