A battery is located under the hood of the 2015 mercedes benz c300, look for the large black box that has a red and black connector on the top.
The auxiliary battery or converter in the 15 c300 is under the the forward carpet under dash on right hand side. You will only need a T15 torx bit and a 10mm socket to replace. Very easy compared tomost things. Good luck.
