2020 c300 battery?
#4
If it's like my 2019 c300 (which I would find hard to believe it's not), it would be an H7 (or 94R, same thing different name) AGM battery. I got mine from autozone here: https://www.autozone.com/batteries-s...ext=H7+battery. Their fit checker is incorrect. To be extra safe, you can just measure the dimensions of the battery and compare it to the standardized size. However, I'm sure it's the H7 type.
