Battery voltage drop - 0.43V in 33 mins

87 924S
Battery was bought in Dec. 2020. Few days ago it died when my car was parked for a week or two. I charged it. The charged battery showed 13.75V (post to post), but the voltage was slowly dropping. I monitored the multimeter for about half and hour and recorded the voltage drop from 13.12V to 12.69 over 32-33 minutes. The only two things that "consume" the energy are the stock clock and radio's clock.
Is the battery kaput?
