How to install button batteries?

Button batteries are small in size and are widely used in various micro electronic products, 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 motherboard , Electronic watches, electronic dictionaries, electronic scales, memory cards, remote controls, electric toys, cardiac pacemakers, electronic hearing aids, counters, cameras, etc. Button batteries are also divided into two categories: chemical batteries and physical batteries, and chemical batteries are the most common. They are composed of anode (positive electrode), cathode (negative electrode) and their electric contact. As shown on the right. Its appearance is made of stainless steel material and used as the positive electrode. The negative electrode is a stainless steel circular cover. There is a sealing ring between the positive electrode and the negative electrode for insulation. The sealing ring is made of nylon. In addition to insulating purposes, the sealing ring can also prevent electrolyte leakage. . There are many types of button batteries, most of which are named after the materials used, such as silver oxide batteries, button batteries, and alkaline manganese batteries. As for how to install the button battery, the author uses the computer motherboard as an example to explain to everyone. The CMOS battery on the computer motherboard generally uses a model 2032 button battery. The installation methods basically follow the same principle, that is, the positive side with letters is facing upwards. When installing, place the positive side with the letter up in the battery compartment, and press it into the battery compartment. The flat side of the button battery is the negative connection spring, and the protruding side is the positive connection. Reminder: A button battery can make 600 tons of water undrinkable.
