You can replace the battery with a new one, it's just a standard 3 volt button battery. If new batteries are draining quickly then there is a fault on the motherboard itself.

I think their is earthing (ground current) problem of your pc.
Check earthing is proper.
Mobo screw connect with cabinet.
Change battery different store and some other brand.

Possibly an errant conductive path. Clean the board thoroughly

I bought a new CMOS battery about 3 days ago and on the same day after installing it may PC started showing me low battery voltage sign. It was too horrible for me. That I just bought a new battery and on the same day I just got expired! But yesterday I updated the BIOS of my PC and now the low battery sign is not there now. I am so happy 😀 and hope that it lasts for at least 1 year or more.
