Yup, bios battery for sure. If you have a standard pc then it will be a CR2032 and is quite cheap to get a replacement for.

Technically speaking, cmos battery is correct. This battery supplies power to store the BIOS settings whilst the pc is shut down :).
Did you go into the BIOS and set the correct time after changing the battery?

CMOS is correct, but I'm sure the technician knew what he meant (even if a couple of quiet snickers out the back :) )
Do you actually need to reset time at BIOS these days? Have never found the need with modern Windows builds, so long as time syncing hasn't been disabled... could be wrong, so feel free to correct.
