I had the same issue. It’s possibly a software “campaign” to fix a BCM fault which may cause the turn signal to turn on while the engine is off, this can result in total battery discharge. At least that’s what my dealer flashed onto the car and it’s been fine since, typically goes into float on my tender when I attach it weekly within an hour at low amperage.
For a battery tender my dealer’s Alfa/Maserati tech said something with a max of at least 5A for charging a deep cycled battery, 1A is sufficient for floating otherwise. I’m using the Battery Minder 128CEC1 because it’s really flexible on battery types.
Edit: there’s an eyelet on the transmission under the car. Thread a bolt into it to put it into neutral. I don’t recall the dimensions, your dealer or AlfaCare should be able to provide it. I think it’s M6x32
