Thanks for your video Ed! I just did the same job an hour ago, on my GLC 350D -2017. You should begin the job by removing the start-stop-button key first (according to Mercedes instructions) and it is not necessary to mount the battery charger, it maybe for older cars (Mercedes instructions does not say anything about a charger). I didn't use a charger and it all went very well. But I also realized that you can't open the car when the battery is out... I was lucky that my new battery already was outside. My old battery was almost 6 years old (5y and 11m) and we have complained (for two years) to our local Mercedes dealer about two problem. 1. Start/stop don't work. 2. Instrument panel often was turned off during start at winter time. Totally black and you couldn't see your speed or any messages. Mercedes said that we maybe had to changed the whole instrument panel and I even started a case at my insurance company about this. Now I have fixed all these problem by myself and 20 minutes of work for a total cost of about $200 (for a Bosch battery). By the way, I didn't have to change the auxiliary battery. Regarding the Mercedes instructions, I got the info from a friend that is a car mechanic and he looked up my car in his service computer.

Good stuff, I wouldn’t say it’s an overkill with the plastic bag over the cable… if anything it shows that you care about the job at hand and are aware 👍🏼 we are thinking of buying the 250 (4cyl) and this is handy because it will be our first merc and I do all the servicing on our car so I appreciate your input and vids Keep up the good work Cheers from down under 🇦🇺👍🏼👍🏼👍🏼😊😊🇦🇺🇦🇺

Thank you for this video, it helped me swap out my 2016 GLC 300W battery!

Thank you for This video, it helped me swap out My Mercedes Benz GLC 220d 2018.! 🇨🇱

Was wondering why mine stopped going off. Started a year after I got it!

Decent Batt for these cars is now about 350 ish dollars. 250 low end, 400 higher end. YOWWWWWW

Very helpful - that battery looks heavy.

I was doing whatever u r saying and at the end my new battery was in the trunk 🤣

Awesome thank you!

the battery charger i have has 2 settings on it, one is quick charge, the other is normal charge and the last one is trickle charge, its from harbor fright, so do i put it on the trickle charge setting when changing the battery like you did?

Great idea using the trickle chsrger so you wont loose tjr memory.

I replace my battery and it fixed the problem

Glad I didn't first take the dash apart. I will replace my 4 year old battery first.

I have a similar issue. at stop engine ON/OFF is not working also a check engine P2610 code. They told me to change the main battery. Do you think that is a right diagnosis?

Hello. Was your check engine light on when and where you getting a message on the dash stating “turn engine off and leave car running?

Do you plug in the trickle charger before you take of the negative terminal?

TKS for video sir. What ampers is need to be the new battery ?

What setting do you have the battery charger at when you hook it up to the car

I just left the auto shop and got a new battery but the auto stop is still not working.. I was told that was the problem but not working.. they claim they did a diagnostic test

Do you need do battery registration ?

Rich people think you get what you pay for. I can do all that in a 2002 Toyota without doing all that, oh 245000 miles and counting, intelligent stupid German engineering at it again.
