Winterization

My bike's (2024 Triumph Speed 400) been stored securely behind my apartment building for about a month now as I had to leave the country for the holidays. The day before I left I had the bikes first service (600 miles), I filled up the tank, disconnected the battery, and just covered it.

I'm planning on leaving it there for another month. Is this enough or should I have added fuel stabilizer and taken the battery out and brought it in?

This is my first winter with a bike....

Edit: Thank you all. Fuel stabilizer, battery tender, and some WD40 to get the f**kn U-Lock off….ordered.
