Hi,
normally you should be able to do it but each time you will get to set the BIOS.
so, better you get the battery replaced.

If your cmos battery fail when your pc is loaded and you go to shut the system down by any chance does the pc boot backup without you pushing the power button? if this is the case then your cmos battery is on its way out. the cmos battery is there to save data in bios. you can change one really easy and simple on your motherboard it look like a watch battery just buy a new one and replace the old your pc will be as gd as new

hope this information helped mate
