The last EVGA motherboard I had was an X99 and now my current Z390 board have both had their CMOS batteries need to be replaced after about 1.5 years. It's not a huge deal but in my 20ish years of using computers I've only recently started having to replace these batteries during the lifetime of the board.
 
Just an FYI :)

    Alex, i only have 170 ftw, but the CMOS battery as you say is 3-4+ years life.  I wonder if the newer boars are using more power when they sleep ?  I have my MOBOs sleep about 12 hr. /day

    If you use a power strip that stops all power to the PSU or the switch on the PSU ... then the CMOS battery is being used.

    I've had my PC on a UPS for probably the last 3-4 years so aside from when I've specifically unplugged it, it never loses power. Maybe I'm just going crazy...

    you'd think after all these years we don't have a good option to the cmos bat. You'd think they would be a thing of the past by now.

    Does turning off the PSU switch(and unplugging the PSU power cable) help to prevent battery drain?

    That makes it die faster, if anything...  The battery is necessary when there is no other power in the board to hold the data in the cmos chip (bios/uefi)

    What you're saying is this is with the psu switch in the off position/surge protector off/ups off, correct? Referring to when you say the batteries last 1.5 yrs. I never leave my surge protector or power to psu off. Like ever. Gursd thats why I never have issues with having to replace cmos batteries yet. G1 sniper m5 from z87 era still works.
