the purpose of the rechargeable battery-operated on a system board is?

to save your memory stored and also to run your clock for time. If youhave a bad battery-operated or rechargable battery you wil see the system clock lose time.
To argue stored memory settings when the AC power is off somewhere flash memory can't be used.
to remember the system time when you turn it off (provides power to the clock). when it go flat, the computer resets the time to 1 JAN 1970 (some newer machines have a different Epoch).
I wasn't aware that here was a rechargeable mobile on a system board. I know there is a CMOS mobile to ensure that the settings and data of the cmos is preserved when computer is sour, but that battery, as far as i know, isn't rechargeable.
The motherboard mobile is used to preserve the computer's time and BIOS settings while the computer is turned off. Some motherboards simply need the battery-operated in shield of a power outage. They draw the needed electricity from the electrical outlet to power the clock. These motherboards save their BIOS information to EEPROM. EEPROM stands for Electrically Erasable Programmable Read Only Memory.



Most of these battery are not rechargeable and have to be replaced every two to five years. You'll know when your time is no longer correct.
