Once the battery is replaced turn on the computer and resetting the CMOS values to the defaults. After the values have all been entered make sure to save the settings before exiting. Many CMOS setups allow you to press a key (such as F10) to save values and exit all in one action.
If after following all the above steps you continue to experience the same error when your computer starts or your computer is still unable to keep the stored values it's likely that you're experiencing a more serious issues. Most likely causes are bad power supply or bad motherboard.
Three common reasons for losing CMOS data include power loss, such as when a computer is unplugged or the battery fails; hardware changes, like replacing the motherboard or removing components that affect the CMOS chip; and corruption due to malware or software errors, which can disrupt the settings stored in the CMOS. Regularly replacing the CMOS battery and ensuring proper shutdown procedures can help prevent these issues.

There are none. One is a battery which is used to provide passive power to the CMOS chipset to keep it from clearing itself.
The CMOS RAM battery is commonly referred to as the "CMOS battery." It is typically a small coin-cell battery, often a CR2032 lithium battery, that powers the CMOS (Complementary Metal-Oxide-Semiconductor) memory. This memory stores BIOS settings and system time when the computer is turned off. If the CMOS battery fails, users may experience issues with system settings and time retention.
Most likely the small battery inside the case that powers CMOS RAM needs replacing.

Chances are that the CMOS Battery on the motherboard is dead and needs to be replaced. Without this battery, the computer can not remember the CMOS settings when the power is turned off.
