Comment 6 for bug 1898829

https://www.kernel.org/doc/Documentation/rtc.txt

just a bit of info on rtc drivers. While rtc is something, it's not necessarily the cmos battery, it's just a chip that the system can use to determine time. So it would not be a cmos battery it would be an RTC battery, since there would be no way for inxi to know what it was, there can be more than one for example.

This bit of data is unlikely to make it into inxi I have to admit since I would need to see much more information about variation and > 1 rtc systems and systems where the battery was dead or whatever else can happen, but in no case would it be a cmos battery state, it would be an rtc chip state, but, again, since I have no real data on this, no examples of complex systems, etc, it's unlikely this will be added.
