일반적인 메인보드 배터리는 CR2032 사용합니다.

메인보드 배터리 CR2032

 

 

 

 

컴퓨터 메인보드에 사용되는 배터리의 규격은 CR2032입니다. 한 번 구입할 때 200개 정도 구입합니다. 아래 사진은 방전된 배터리 (200개 가량) 중에서 가운데가 볼록하게 튀어나온 제품이 있어서 분류를 해봤습니다.

I think it is the second most used computer repair accessory after screws. I think the Simos battery on the main board is used for 5 years and usually 3 years when it is used for a long time. I don't know if there is an initial defect or if it is left unattended without electric connection, it will discharge quickly, but there are cases where it will discharge within 1-2 years.

 

 

 

 

CR2032 200 batteries

 

​

 

When I bought the batteries, I classified the batteries that I replaced before.

 

​

 

The replaced battery is also new, and products measuring 3.0V or higher can be reused, and other batteries are almost dead, so we will dispose of them. (If you take the batteries to the district office, they will exchange them for tissues or batteries, but it is not easy to visit the community center, so I think I will put them in the apartment battery collection box.)

Classifying discharged batteries

 

​

 

One of the characteristics of discharged batteries is that the center of the discharged battery is often convexly raised. I have collected only the batteries that stick out when you stand out or touch them with your fingers (like laptop or smartphone battery swelling).

Among the batteries with a protruding center, the CR2032 battery with the name KTS is the most. (Later, KTS was the largest among the discarded batteries. It seems to be a battery from the CR2032 manufacturer, which is mainly used by mainboard manufacturers.)

Dispose after organization

Finally, it is organized as follows. The number of waste batteries called KTS was the highest. Since there are many discarded batteries, there are many KTS products that are convex. (NEWSUN, MAXELL, DBV, JHF, Japanese, LIXING, BEXEL, DURACELL, ENERGIZER, PARASONIC, SONY, GP, MITSUBISHI, and TIANQIU came in in order.)
