After about half year of usage I found the clock shows wrong time until it get it from sat. I did not think it is something wrong to the camera until after warranty period I had to open it to replace LED display. I found the small battery related to real time clock is drawn.
As this is rechargeable battery and should be charged by clock chip, I bought new same battery and replaced it. After while I found that battery is not charging. I wonder if it is issue with firmware (Fi-27) or clock chip is faulty. As a last resort option bigger size NOT rechargeable battery can be installed and it should be good for several years. Any ideas?

10 years, many dashcams
The RTC button batteries in dashcams are most often soldered to the PCB, you can replace it if you have tinkering skills and a soldering iron.
But it is nothing like replacing a battery on a watch.
