X670E Aorus Master bios battery draining very quickly

[gijoe50000]

So I recently got an X670E Aorus Master and the bios battery was DOA, not holding clock or bios settings; and spending 15 minutes waiting for memory training every day is a nightmare, so I have EXPO disabled.

In HWinfo the bios battery is reading as 0.840V.

Ordinarily I would just swap out the battery, but in this case it looks like a full strip down of my watercooling loop is needed...
And I will also have to remove the motherboard from the case...
And remove the backplate from the motherboard...
So that I can remove the screws for the chipset heatsink...
To remove the heatsink...
Just to remove the CMOS battery.

Now I have no problem doing this, once, maybe twice if I still have this board in 5 year's time, but what I'm worried about is that there's a lot of talk online that the CMOS batteries just don't last very long in these motherboards. And I don't want to have to come back in 3 weeks to replace the battery again, because I'll only have just recovered from the trauma of doing it the last time.

So I'm wondering if anybody has any information on this, like is there something else on the motherboard drawing power from the CMOS battery?
Was it just a bad batch of CMOS batteries?
Or maybe some of the earlier bios versions were doing something funky with these boards?
Or perhaps some setting in the bios that I can turn off?

Anybody have anymore info on this?

All the battery does is hold the setting in the cmos. Once you replace the battery and it does it again I would contact support. Why would they do this in the first place. By putting a battery under a heat-sink???

I know right! It seems like an incredibly stupid decision, especially considering that they must have done something to the bios to make the battery drain this quickly, maybe connected the bios to the RGB on the board, or the way it connects to the desktop or something..

Greetings,
Will be curious to hear what you decided and if replacing the battery worked.  I've seen this type of design in other products as well.  Cameras specifically.  Some have a replaceable battery, others require a teardown that you as an end user don't want to do.  All for a .25 cent CR2025 battery.
