2005 Escalade ESV battery voltage too high

Likely a bad cell in the battery
I had this happen before and replacing the battery fixed it after having it load tested(which of course confirmed what I already knew)

Why do you need to reply the same as me? A bad battery in almost always caused by 1 or more cells being dead. You cannot change cells in Automotive batteries.

Did you ever think maybe it was to confirm to the op by giving a second opinion?
Gees chill out
I know you can't change the cells in automotive batteries no need to be obvious about it
