>battery is there to remember settings such as time and
start up settings not quite sure how long batteries last
(i think round about five years) but you willknow when it
is time to replace it as the clock on youe pc will lose
time, it is easy to replace and easy to find, it's looks
like a large watch battery on your motherboard.

All motherboards have a battery which is usually circular and around 20
millimetre diameter.
This holds the special bios settings if so arranged.
It means that you would have to manually reset the bios every time you start
the PC if the battery died.

The modern computer with "ATX" system is always on if your mains power is
left connected.
If left connected, your internal battery has nothing to do.
Hence it would last for many years.

Wrong! The type of batteries used has a definate shelf life. It will die
whether being used or not.,
