2019 c300 battery

Just purchased a 2019 c300 may 28, 2 weeks ago I get a notification about my battery saying I need to park it and let it run, I barely drive it because I work from home and everywhere I need to go is a 5 miles radius, what would be the reason for battery to be partially charged

You answered your own question, every time you start the vehicle, the cranking uses battery power, if you drive it for that short of a distance, the battery doesn't have time to charge up what was lost every time the vehicle is started. That is also bad for the engine as your vehicle can never reach operating temperature, make sure to take the vehicle for a 30 minute highway drive every week or so to keep the vehicle in top shape.

That said, if you can't drive it for at least 30 minutes on the highway every week, consider putting your vehicle in standby mode every time you arrive home (as it disables every time you start the vehicle). It is under vehicle settings. Make sure your vehicle is in a secure place because standby mode deactivates the anti-theft system.

2019 W205 FL C43 AMG Saloon Selenite Gray
I also just purchased a 2019 C43 AMG Saloon (300). Within 3 weeks of ownership and just turning 30,000 miles, I received the same message. I went to AutoZone and they checked my main Battery for free. It turned out to be bad. I replace it with a Duralast Platinum AGM Battery. I swapped it out right in the parking using their borrowed tools. My vehicle has been working like a charm. Message is gone. Most batteries only last 36 months nowadays.

Now to answer the impending question.... "Yes", my car is still under warranty. You may ask why I purchased my own battery? Well, because of convenience and partially laziness. For about $230 and maybe 30 minutes of my time, I fixed the problem. I didn't have to deal with the hassle and time it would have taken to get my car fixed at the dealership.

Caveat: Main battery fixed my car's issue. Your issue may be different.

I found this helpful.
