Alternator battery or parasitic draw

Diagnosing/Repair

Going to get it tested soon, just curious on some initial thoughts.

2019 outback

Drives distances fine. Work being 30 miles away. Needs jumped after a 4 hour shift

Also needs jumped in the morning.

Sometimes needs jumped after a short trip, 5 or so minutes.

I do all my jumping with a jump box, never fails.

Autozone says alternator needs replaced, but im seeing their test may be misdiagnosing.

Any thoughts, questions, just lmk
