      Technotech Lithium Cell CR2032 CMOS 3V Battery(5 Pieces), Gray M.R.P.: ₹399.00 Price: ₹110.00 You Save: ₹289.00 (72%) Inclusive of all taxes.

      Is CMOS battery important?

      The CMOS battery is an important feature on motherboards, and will trigger a beep code when it is going dead. It is best to replace it, because it doesn’t just hold time or date but BIOS settings. Modern boards hold the similar settings in non-volatile memory so that they are not so easily erased.

      Does motherboard battery need replacing?

      If your PC displays errors about the clock or CMOS when starting the PC, the CMOS battery on the motherboard probably needs to be replaced. Desktop PCs use a battery to keep time when the they are off, much like a watch. Like a watch, the battery needs to be replaced when it runs low on power.
