I'm making a button cell battery for my motherboard and I'm using CR 2032 lithium manganese button cell batteries with a voltage of 3V. The motherboard uses it to save data and doesn't have many uses particular. Currently, the motherboard used is imported from Japan. Most of the batteries come from China, but in fact, there are many manufacturers of such batteries in China, especially in Guangdong. The quality is definitely not as good as imported batteries, but the main difference is only in appearance, materials and testing. in certain extreme conditions, the capacity will of course be higher than that of China and the flow curve is much more stable.
As for the poster, you can just go to the supermarket and buy a CR 2032. I don't know the price at the supermarket, but it only costs 20 cents for me, and the most the the quantity the betterEast. . . . . .
This battery is very inexpensive. It will cost you a few yuan if you go to the supermarket to buy it. You can eliminate the possibility of leakage. If this type of battery were to leak, it would be gone. already leaked.
My personal suggestion is to go to the supermarket to buy batteries from brands such as GP, VARTA, Penghui, Harry Tong, etc. Never go to watch stores (the batteries there are very bad) or large supermarkets like Wal-Mart. There are certainly choices among the brands above.
