That clock/cmos battery is a racket because a tiny solar rechargable
battery could be used for the clock and the bios settings could be
stored in nonvolatile memory eeprom.

They had rechargeable cells in mobos a few years back. They were a disaster-
they would leak, often long before the mobo was obsolete, and the chemicals
would eat through the traces of the mobo rendering it useless. Also, they
were not user-replaceable.

Lithium cells are a huge step forward IMO, they don't leak and are
user-replaceable in seconds. I'm not sure why you feel they are a racket-
they generally last the life of the mobo (in terms of obsolescence), and
when they don't they are, at least in my country, extremely cheap to replace
and widely available.
