I got a Pi 5 with an Argon OLED case, which also supports RTC battery and I installed that. I found that the time clock will restart from the moment before power lost, so that when I turn on the unit at home it shows about the time I left office, until internet available. I wonder if there is anyway I can check the battery status with a command, so that I will know of a flat battery, thanks !
