Mercedes-Benz W205 C300 Battery Replacement DIY (2012-2018 C250 & C350)

► The battery is an essential part of your Mercedes W205 maintenance cycle. It is responsible for providing the power needed to get your car running. When your battery starts to fail, you may experience longer than normal crank times in hot and cold weather, see error messages on the dash related to certain convenience features, or your eco start-stop may cease functioning.

Whatever the case may be, if you are experiencing any of these symptoms or have purchased a used vehicle and don’t know the history of the battery, this video will show you how to get the job done. From swapping the old battery out to putting the new one in, and also showing you how to reset your W205’s auto window function, Kyle Bascombe, FCP Euro’s Mercedes Catalog Manager has you covered in this DIY.

Mazen Kanso says:

Thanks for the video, the error disappeared once I changed the Voltage Converter Module, but on the screen the ECO light does not show up anymore and it does not start/stop even though the switch for ECO in the center console is on and lit green. Does it need some kind of hard reset. Thanks again

Slava Zayarny says:

FCP Euro, thanks for putting out valuable content like this. Please comment on:
1) The need and the tool to update the front SAM with that fact that battery was changed. Factory service manual seems to require it.
2) Your suggested approach to preserve memory settings such as radio stations, clock, etc.

I thought all these new Benz models needed a battery registration to the front SAM (N10/6) like BMW now? Great video!

Baud ToTheBone says:

Odyssey makes a fantastic battery. I have one in my Benz and it has lasted 10 years so far. Make sure it is always completely charged. Keep it on a trickle charger (noco genius is good) if you store your car over the winter.
