The motherboard battery is usually a 3V lithium battery. This is because the motherboard battery is mainly used to save BIOS information and clock, it needs a long-term stable voltage supply, in lithium batteries, the voltage is relatively stable, and long service life. At the same time, it is worth extending that lithium batteries have high energy density and capacity, are not easy to leak and memory effects, and have become one of the main energy storage methods in modern electronic devices.
The motherboard battery is usually 3 volts. This is because the main role of the motherboard battery is to provide power to the
CMOS chip to keep the computer clock and BIOS Settings
correct. In general, 3 volts is sufficient to maintain these basic functions
. For more information, consult your computer motherboard manual.
The battery voltage on the computer motherboard is 3V. The computer motherboard button battery is used to record the time of the computer system, that is, to maintain the accuracy of the system clock, when the power is insufficient, the time will be back to the factory date, and to record the hardware information used to boot, that is, to maintain the CMOS BIOS information.
