Is my battery dead or could it be something worse?

 Good morning everyone, I have this issue with my car where it will crank but it won’t start, the crank gets weaker on each try until it doesn’t crank at all.

 

The battery is 2 years old and 1 month ago it has been sitting for 2 weeks straight with the radio turned on by mistake while I was somewhere else, until the car ran out of battery and I had to jump start it, it worked fine like that but today I have woken up to this issue, I just wanted to know if it seems like just a dead battery or something else could be the issue.

 

 I manually bleed the fuel using the fuel filter primer and there’s no air bubbles in the fuel, the spark plugs seem fine, the car always has a rough idle but I guess that’s because the IACV must be dirty and I’ll have to clean it, it usually starts on the second try.

Sounds like a dead battery. You should charge it completely and then measure the voltage.

+1 for putting it on the charger for a while. I would also check that the battery terminals are clean and tight.

 

If it still cranks slowly after charging, the battery itself could be damaged. Going dead flat is hard on batteries, and so is sitting around while dead flat. Hopefully yours bounces back.
