How long can a button battery be used on a desktop computer motherboard? what's the effect? No electricity computer can boot it?

Answer:

Battery life = battery power / G3 leakage current (G3 state: power off, the board lights do not light), generally can be used for 3 years.
The battery can generally use 8 years, at least I was like this, no battery can boot, but the date and time will not be retained, the other nothing.
That is the BIOS battery, record some of the settings used in the computer, such as time. If you do not have electricity you will find that every time after the boot is zero. Life should be in about 3 years, sell 5 dollars a piece of money.
