new 12 volt battery.
when the old battery died, i assumed it was old age and replaced it.
i am out of work with an injury, only using car once or twice a week, since i put in the new battery.
after sitting for 4 days, battery was dead. doors would not unlock. display would not light up when i opened the door.
assumed new battery was not fully charged, charged it for an hour. shop charger/starter, not a trickle charger.
next day, dead. jumped with portable jumper. drove for two hours, stopped twice. car started.
i am assuming it is not the battery because it holds the charge for a few hours.
i searched on here and saw similar problems with suggestions of a bad battery or onstar drain.
my onstar is not active.
i am thinking of charging and then disconnecting the battery and let it sit for 2 days.
if it starts, i believe that will eliminate the possibility that it is the battery.
if it starts, i will then try pulling the onstar fuse, F9, is it?

anyone have any thoughts or suggestions?

Something is running or shorted. Do you have paired bluetooth phone? That would be my guess. The car is still running the bluetooth connection even though you removed the phone.
