Can two thin 3v button cell be replaced with new 3v?

No way! What I want to talk about here are two CR20 16 on the vehicle remote control. According to the high end, the height of a CR2032 is just right!

If it is in series! The voltage of the two batteries became 6V! Change the high-end OK CR2032 voltage and you can't move the product! I hope I can help you!

I also take this opportunity to popularize the knowledge of button lithium battery: CR2032 button lithium battery, the voltage is 3V, in fact, the voltage of the new battery is about 3.4V, and the voltage of high voltage 3V is a virtual voltage, which means that the voltage time from 3.4V to 3V is relatively short! CR of CR2032 stands for lithium manganese dioxide primary battery, 20 stands for diameter: 20mm, and 32 stands for height: 3.2 mm Button lithium battery is an environmentally friendly battery. The criteria for judging quality are capacity and storage time. The international nominal capacity of CR2032 is 2 10mAh (that is, the working current multiplied by the working time, that is, if you are 0.06544, you can work about 210/01= 21000 hours). At present, foreign batteries such as Panasonic, Sony, Wansheng, Mitsubishi and Ranta are all 220mAh, while domestic batteries such as Ruhu, Li Jia, Li Xing and Gaoneng Da are also 220mAh. CR2032 of Shenzhen Lida battery is.
