Headlights stay on for almost 10 min after truck is off

I have a 2021 F150 Lariat (about 57k miles now) and was having an issue with the truck entering 'battery power saving mode' when I shut off the truck. The car would do the 3-note chime when the driver door was opened and the headlights would stay on for like 10 minutes after the truck was shut off. Ford checked it out and determined the battery needed replacing, which I suspected and that seemed to fix the issues for about 4 weeks until yesterday it started doing that all again! Headlights staying on for and exceptionally long time after the truck was shut off. Has anyone else had a similar issue?
