Motherboard batteries, also known as CMOS batteries, typically last for several years before needing replacement. These batteries are primarily responsible for maintaining the system’s BIOS settings, such as date and time, when the computer is powered off. When they start to fail, you might notice issues such as incorrect date and time settings or BIOS errors during startup.

Motherboard batteries typically last around 5 to 10 years. They keep the computer’s internal clock running when it’s turned off and store BIOS settings. When they die, the computer may lose track of time or settings.
