how to change memory battery on acer aspire 8920g

Solution
What do you mean by internal memory battery? The only internal battery I know is the one on the motherboard which keeps the BIOS running.

I need to enter date/time in set up when starting the PC. It's due to replacement of the CMOS battery.
My challenge is to replace this battery and it seem to be a rather delicate job for an amateur.
