I wonder if they've actually be designed to that, or people have just
observed that behaviour, and made an assumption.  I've certainly fixed
up a PC with a new battery, one that exhibited no clock problems.  The
battery was definitely low, resetting the BIOS parameters didn't help,
replacing the battery did.

In this day and age you'd expect that there ought to be a positively
identifiable alert that the battery was going flat, such as a message
saying the CMOS/BIOS battery needs replacing.  One that the BIOS
displays while booting, and another that the OS displays while running.
It's arcane knowledge that a clock might be off because of a battery on
a mains powered PC, not one that the general public would be expected to
know about.  And I wouldn't put it past some people, with prompting from
a vendor, about a PC going wonky, to replace the whole machine instead
of the battery.
