In your case, I would not change it until it fails. "Don't mess with what ain't broke!!" It may last as long as you have the computer, or you may meet a cmos-savvy person. In the absolutely worst case, you could have a tech do it for you at a computer store. It might take her a half-hour to get it set up again. It only takes a couple of minutes to change most batteries. It all depends on what kind of computer you have and how close the default settings match what you need. If you ever need a good reference on the cmos settings, you can try www.rojakpot.com. If your computer has run fast from day one, I doubt if it has anything to do with the battery.

Make sure that you know how to enter the cmos settings screens and that you have your manual ready to help you set them. Dean Kukral<< ~~~Oh boy, I have no idea how to do that and don't have a manual that tells how to do it. (My battery is over 5 years old, but it has made my clock run fast from the very beginning.) Do you know of a link for good directions on CMOS? I'm probably going to run out of battery any time now, and should replace it.
