However, the life of the battery gets extended to 5 years when you use it regularly. The battery provides power to CMOS memory and the real-time clock. Signs of a CMOS Battery Failure Recently the Windows clock on my Asus K53 laptop started showing the wrong time. It was set to update automatically fro If you don't keep the PC plugged in, the CMOS battery will drain much, much faster and will have to be replaced much sooner. The general lifespan of a cmos battery is actually around 20. sounds more like the CMOS just had to be reset as opposed to the battery being dead. those things last years. you'll be ready to upgrade well befor What is the standard CMOS battery? CMOS (short for complementary metal-oxide-semiconductor) is the term usually used to describe the small amount of memory on a computer motherboard that stores the BIOS settings. A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. I have read more than one time that you should get on average about 5 yrs. out of a 2032 or any typical lithium watch battery. But then I am sure t You need to use the computer regularly to extend the life of the CMOS battery. I've personally fired up computers 10+ years with no use and still had cmos information stored by battery. I wouldn't count on that as the norm but Life of battery (down to 0V): Normal Case (leakage current = 4 A).
