So I have an MSI b850 Gaming Plus Motherboard that was purchased 4 months ago. When I turn off my PC I always leave it unplugged due for safety. In around those 4 months my CMOS was drained to 2.760 V, and I kept checking it in HWiNFO for 3 days and it stuck there. So I replaced it with a new GP CMOS CR2302. Day 1 the voltage was 3.296, at day 2 the voltage is at 3.244, at day 3 the voltage is at 3.22, at day 4 the voltage became 3.196V. I dont know if this is normal for a newly bought battery, will it stop dropping for awhile at a certain voltage? My pc still remains unplugged when turned off.
