Hello @nvko23 solitaired

after opening my M5StamPLC I found that the RTC battery is located at the underside of the CPU board. It is soldered to the board. So yes, I'd say it is replaceable, but the proper soldering tools are required.

BTW: the RTC battery in my M5StamPLC seems to be completely flat as I measure 0 volts.

Thanks
Felix

Great, thanks you very good
