Weird problem, car just not starting

Nektsune

I didn’t know where else to put this but I’m just having this problem last night and I’m not sure what it is.

I have a 2010 model and I came back into my car from picking stuff up from home, after getting back in the car just seemed to fully lose power when I pressed the button the start it up. No clicking sound like if I had a dead battery nothing for a bit. Got out of the car to check my battery and everything was fine, light turned back on in the car again. Going back in to start it, it all turned off again. I’m assuming it was just a battery problem and might have to get a new battery. 3rd time around it started. Ran fine and normal to and back after going back out.

Today I just left auto one to just check my battery and it’s fine but idk what that problem was at all?

After a bit today now it did it again? I’m still unsure what the problem is that makes the car not start. But now I’m hearing a small tiny noise coming from the radio area.

Does anyone know what this is or had this same problem?

I’m a lurker in this forum and I’m not sure if I put this in a good place or not
