I thought of the rtc battery implicitly being the same powering the bios
memory, that is to keep ahci settings for example until next power up.
Sorry for having been misleading here.

I've never
seen a bad RTC battery cause a panic on a PC system, and in fact, some
OpenBSD
supported platforms don't even have a battery backed RTC. I've
installed and
ran OpenBSD on a lot of machines with dead batteries.
