There are many styles of button batteries, from large to small, from thin to thick. Most button batteries are primary button batteries, which are dry batteries, but are different from the usually large and long cylindrical No. 1 and No. 2 batteries. Common dry batteries such as AA and AA are obviously different in appearance. So do you know how to install button batteries? I will explain it to you below.

How to install a button battery? The specific method is as follows:

Button batteries are small in size and are widely used in various microelectronic products. The diameter is between 4.8 mm and 30 mm, and the thickness is between 1.0 mm and 7.7 mm. They are generally used as backup power sources for various electronic products, such as computer motherboards. Electronic watches, electronic dictionaries, electronic scales, memory cards, remote controls, electric toys, pacemakers, electronic hearing aids, counters, cameras, etc.

Button batteries are also divided into chemical batteries and physical batteries, of which chemical batteries are the most commonly used. They are composed of anodization (positive stage), negative electrode (negative stage) and electric contact liquid. Its surface is a stainless steel plate and is used as The positive stage and the negative stage are annular covers made of stainless steel plates. There is a sealing ring insulation layer between the positive stage and the negative stage. The sealing ring is made of polyester. In addition to serving as an insulating layer, the sealing ring can also prevent the leakage of lithium battery electrolyte. There are many types of button batteries, most of which are named after commonly used raw materials, such as silver oxide rechargeable batteries, button rechargeable batteries, alkaline manganese rechargeable batteries, etc.

Regarding the installation of primary button batteries, let’s take a computer motherboard as an example. The CMOS battery on a notebook motherboard usually uses a button battery of model 2032. The installation methods basically follow the same standards, with the positive side of the alphabet facing When installing, place the positive side with English letters facing up in the battery compartment, and press it firmly into the battery compartment. The flat part of the button battery is the negative connection spring, and the protruding part is the positive connection protrusion.
