Giulia Quadrifoglio electrical glitches – battery or alternator?

Okay so I’m hoping someone here has dealt with something similar because I’m honestly getting a bit worried about my Giulia. Over the past month or so, I’ve been getting these random electrical issues that come and go. Sometimes the infotainment screen will just go black for a few seconds, other times the auto start-stop will throw an error message, and yesterday the instrument cluster flickered for a split second while I was driving. It doesn’t happen all the time, maybe once or twice a week, but it’s enough to make me nervous. I took it to a general workshop and they plugged in a diagnostic tool and said there were some low voltage codes stored but nothing specific. They suggested it might be the battery starting to fail because these cars are really sensitive to voltage fluctuations. The car is a 2021 model and I think it’s still on the original battery so it’s about four years old now, which seems reasonable for a battery in this climate. The thing is, I’ve heard that Alfa Romeos, especially the Quadrifoglio models, have very specific battery requirements and you can’t just put any battery in there because it needs to be properly coded to the car’s computer. I’ve been looking around and I’ve seen some recommendations for a Reliable Alfa Romeo battery replacement in Sharjah from a few guys in the local car club, but I wanted to get more opinions before I commit. Has anyone here actually had this kind of intermittent electrical issue and did a new battery fix it completely? I’m trying to avoid a costly trip to the dealership if it’s just a simple battery replacement, but I also don’t want to go to some random place that doesn’t know these cars and ends up causing more problems. Any advice would be really appreciated.
