Usually a faulty CMOS battery won't produce beeps -- a faulty clock chip, however, will. Run the Dell diagnostics on the system (F12 at powerup). If you see an error relating to a bad system clock chip, it's the mainboard that will need to be replaced.
The CMOS battery is not even used if you have a charged, main battery in the system or the AC adapter is plugged in.
Changing the CMOS battery requires quite a bit of tear-down (removing the system board):
