2010 Hyundai Sonata - Battery issue, car keeps dying every few months

Hello, I need some help with my car as I have been having constant battery issues for the last few years, multiple replacements and the car still dying. I'll try to give a quick history of the car.

I bought the car used in 2019. Drove it for about 4+ years with no mechanical issues at all. My car died randomly in 2023, figured the battery might be bad so I got a new battery and the car worked just fine. 2-3 months later, car died again. I took it to the dealership I bought it at and had them take a look at it, they found no issues with the current battery but since I had recently got it, maybe it was a bad battery. I got it swapped and put it in the car. Few months goes by, car dies again. I ask the dealership to check my car for a parasitic draw and they can't find anything to indicate that this is an issue. I start dealing with constant car dying issues every few months from 2024 until now. I have always been able to jump the car and drive it, but then it just dies a few days later. I even made it a point lately to use my car to drive around town when my wife and I go out to make sure it can recharge the battery enough.

I had to get an emissions test in January and had no choice but to get the battery replaced again so I did, and my car is dead again this morning. Anytime I've brought it somewhere to have it looked at for a parasitic draw, they find nothing. I jump the car and drive it around but then within a month the car is dead again. Any advice on what might be causing my car to die so often?
