I have a drain on my battery with key off, my tester only goes to 150ma so I can’t tell how much drain it has. The drain is from the ADS fuse, Radio fuse, and the Accessory fuse 2 in the power dist. control under the hood. Pulling all three fuses drops the drain to 30ma, putting only one of the three will push my gauge over max The fuse box inside the car made no difference pulling one fuse at a time.
If the battery is more that four years old or getting close, I would replace it first.
Shorted battery internally(most common) but you can check the Parasitic Draw. Pretty close to the same thing here :

The battery is new because that’s what I thought was wrong.
