Built-in tire pressure sensors can actually be replaced with batteries, which depends on whether you have the ability to do it.
The first step is to pry open the back cover with a tool (feel free to pry, it is soft rubber inside, and it will come off with a little force)

The second step is to scrape the glue on the back clean with a small card, remove the four small screws, and use an electric soldering iron to melt the joints at the box (if there is no solder absorber, melt it while prying it)

The third step is to expose and remove the battery.


Once measured, only 0.07V was left from 3.68V…

Put it on the newly purchased battery, how did you remove it and put it back in like this. It’s as simple as that. I used 955 glass glue to cover the lid. I just need to apply a little bit on the edge of the lid to make it easier to replace it next time.
