Dekstop Computer Date and Time Incorrect?

I have a desktop computer that is running Windows 8 Professor, 64 bit with 2GB of RAM. It is a old computer that I upgrade to Windows 8 but runs very efficiently. It was running Windows 7 Home Premium before. However I have notice every time I turn on the computer running Windows 8 the date and time is incorrect and so I have to manually change it. Once I change it and the next time I use the computer and turn it on, the date and time is incorrect again. I am not very knowledgeable on how to fix this, Is it because of the battery that is on the motherboard ? Does that battery needs to replace ? How much would that battery cost ?

Thanks for your help.
