Difficulty Starting

Over this past week, I noticed my 2009 C300 struggling to start after a couple days of not driving. I took the car out yesterday afternoon with no problems, but when I took it out at night, it wouldn't start after dinner (interior lights and center screen still working). Jumpstarted it and was able to drive it home with no issue. This morning I attempted to start the car, but it wouldn't start despite interior lights and center screen still coming on. Took it to Autozone to have the battery tested, thinking the battery was the issue, but they said it was fine. Not sure what's wrong...any suggestions?

It's the battery, if a jumpstart helped. Replace it.

Even though the battery was replaced about 2 years ago and car passed battery performance test a couple months ago during a service at the dealer?

I have a suspicion something electronic is draining the battery...

I would, but that's just me. Batteries don't last that long anymore sadly.
