CMOS battery in my PC acting weird

Hey yall. This problem arised a few days ago (I think 3 days ago).

THE INITIAL PROBLEM:
I woke up and decided to use my PC. I got bugged out when it wouldnt turn on.

MY ATTEMPT AT FIXING THE ISSUE:
A youtube video later, I realised that my CMOS battery could've just ran out of juice. So I decided to put in a new battery and it worked! My PC turned on and I could use it for around 2 days.

THE LATTER PROBLEM:
After 2 days or so, guess what? It wouldnt turn on again. I knew it was the CMOS battery, but I couldn't understand why it didnt turn on. Its a new battery... Out of curiosity, I waited 5 minutes, and instead of putting in another new battery, I put the same one into my PC (The one I used to fix my initial problem). It worked, oddly.

MY CONFUSION (AND WHY IM EVEN MAKING THIS POST):
I heard from other forum threads/posts that the CMOS battery running out so fast could be a mobo problem. Which is what im thinking of right now. But the fact that I could reuse the battery by just plopping it out and putting it back in after 5 minutes really confused me. Does anyone have a logical answer to this? Maybe it could fix the whole issue at hand, because Im not sure when the same thing is going to happen again.

The voltage measurement with a VOM. 3 volts DC.
An old battery has had the slow acid effect that makes a battery work. After a time the battery goes dead. A new fresh battery with the expiration date showing that it is not expired.
Why would the old battery wear out? They are not rechargeable. You would just show a date that is the original starting date when the CMOS was made if it is a battery issue.
