CMOS battery type for Rampage 6 Extreme?

GEEKCPA
Level 8
I started a build about 4-5 years ago with a 7900X on a Rampage VI Extreme, but I let it sit without use for several years. Now I think my CMOS battery is dead as I get a prompt to press F1 and reset AHCI or RAID in the BIOS. I get this prompt only if I have previously turned off the power to the MB, it boots fine if I leave the power to the MB on at the PSU switch.

What type of battery is used in the Rampage 6? I've scoured the manual and find nothing specifying which battery to use. Worst part of all this is I have to drain the coolant from my system and disconnect some fitting to remove the video cards to access the battery under the 2nd video card. (two 1080Ti's is SLI)

Any help you can give me is appreciated.

When I found out that I had to fully disassemble my system to get at the battery, I just ripped off the ****** "armor" from the board.

Then I saw the battery! WTF Asus???!!!

So I snipped off the wires and soldered them onto a good battery! Screw you!

Yes I know, heat and L-ion don't go well together but who cares. It worked and I saved myself a chunk of time.

Never again asus,never again...
