Simply put, this is the most concise, informative and well thought out repair/replacement video I’ve ever watched on KZfaq. Your editing deserves high praise sir.

I never repaired anything in my C300 2017 4matic but after following the same steps showed in video helped me succeed replace my car battery and battery fitting is perfect. Thanks 🙏🏻

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.

Great video! One thing I did pick up on was in the beginning you mentioned the replacement was a group 49R. At the end of the video you referred to it as a group 94R. I looked at the battery leaving the box and its visible that it is a group 94R

Very useful and concise instructions! Just replaced the battery for my W205 and no issue at all, saving $150 labor at shops

Wow an amazing DIY tutorial and I was able to change the battery on my W205 without any issues. THANK YOU!

It’s crazy because I went to an auto shop and they told me they have to keep some type of electricity flowing threw my Mercedes to change the battery and without it, my car would have to be reprogrammed coasting thousands of dollars and they didn’t have that tool they claimed. That just mean they didn’t know what they were doing. 🤦🏾‍♂️ Thank you for this video

Thanks for the video Did it myself today july 19th 2021 Saved me 200$

Thank you very much. The place I purchased the battery would not swap it out because of how complicated it is. I followed your video and had no issues at all.

Thanks for the share. I went to Advanced Auto Parts today and bought a battery for my 2017 C 300. They however would not install it for reasons explained earlier in your video. I replaced it after watching this video and didn't have to reset anything. Very well-made video. Good job and thanks!

In the mercedes fatory manual they instruct to measure positive terminal that it has the voltage after disconnecting. And it should take some time to voltage to go down. Manual said that if voltage drops instantly there might be some fault on the system. So this also means, that after disconnecting the battery, you need to be extra careful not to short the positive terminal to anywhere ground. There wasn't really downsides with letting the system drain after taking battery out.

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.

Thank you so much for your video. As stated below, it was very specific and well made. It helped me change my battery and you couldn't have made it easier. Thanks again. I will be subscribing to your channel.

More W205 videos please 🙂

This is an awesome video!!! Thank You! for making it. I just replaced the battery, in like 15 minutes because of this video.

I need a battery replacement on my 2015 Mercedes Benz c300. Will my computer need to be reset afterwards?

Is it necessary to update the software so that the alternator charges differently?

I have a 2015 c400 .. can you explain how to remove battery cover as I unblock the 6 tabs but the cover does not come off nearer the windscreen

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

Very professional. Well done for both the content and the video. This fellow is very easy to watch and listen to.

If you put power to the jump start lug before removing the terminals, you keep the computer memory and radio presets.

I’m almost curtain these require a BMS reset to reset the voltage going too the battery. Also mentioning that you put in a 48AGM and put in a 94rAGM.

I want to thank you for taking the time to make this video. I was able to order the Odyssey battery and auxiliary battery from FCP. Replacement was easy with your video. Just curious if there is some kind of reset on battery? Shortly after replacement the yellow battery warning comes off and on randomly.

Great video! I had errors on my W204 C250 cluster and as you have mentioned some functions were not operational. Replaced with AGM 668 battery but errors still appears. What could have gone wrong or is it a start/stop battery in the trunk?

Only thing missing is resetting the battery counter on the front SAM module.

My 2016 c300 has a message in the dashboard saying STOP VEHICLE LEAVE ENGINE RUNNING, and apers and battery logo, should I change the battery to fix that message?

94R, not 49R

Thank you for the tutorial!

Great video! Instructed very well.

Thanks a lot! It was very useful for me!

Thank you for the video

Great vid! Lot of speculation on the need to register the new battery. Can you please confirm if it’s necessary or not? I’m planning on buying and changing on my C63s. Thanks in advance

This is amazing

Wow, perfect 🤩

Thank you!!

I bought a battery from Mercedes for my 2016 Mercedes C300, and they said if I replace it myself I have to bring it back so they can reset the computer so the car can identify the new battery and if I don’t the battery will only last about a year. They said it would cost $90 to do this. Is this true or are they trying to get more money out of me?

Great video, thanks! Question: Does this procedure leave any kind of dashboard message? I oen a C180. Thanks, again!

I want more interest in Mercedes. We want more video to follow you from Saudi Arabia😎👍🏽

Excellent video! Does anyone know if the 2018 c300 has an auxiliary battery and where it is located??

very helpful. Thank you!

Very well said. Are there any other settings besides the radio etc. to reset for the new battery to function properly?

Very good vide0..Well done thank you

My neighbor has this car , he ended up getting a new battery and changed it out..when he put the new one it it didn’t start but all the lights and interior functions worked..saw another video said to do factory reset in the system menu and still nothing…Mercedes Benz is telling him his jumping terminal is ruined and it’s gonna cost 2000 to replace it in order for the car to start…any clue or ideas on what the real issue is

I love cars

At the beginning you said group size 49R and at the end you said type 94. Which is it?

VERY NICE VIDEOS :) THANK YOU :)

Good vid. thank you.

So you didn’t have to take it to the Mercedes dealership for the battery to be calibrated to the vehicle???

My W211 the main battery is in the trunk & I prefer to use the Bosch batteries on my MB

I have a 2018 Mercedes’ Benz 300e and I was told you need a special tool to reprogram the battery to the car. That is what a Mercedes mechanic told me , is that true? Thanks

I am really confused. Just had my S205 in the service today and I told the guys that I have problem with my 1 1/2 years old VARTA AGM battery (leaving engine running message). I drive about 1x each week. Voltage is between 12.0 and 12.6. Now they told me that they initialized the battery (I just replaced the battery and bypassed it, was only unpowered for a few seconds). Some say you have to initialize it, some say you don't have to. Also I found out that the CTEK charger told me after 3 1/2 hours that the battery is fully charged - before the engine had trouble to start (tested twice, took a bit longer and I missed the strong noise) and the "leaving engine running" message also appeared. So the battery "should" be empty. But the charger can only charge it with about 17,5 Ah and the battery has 70 Ah. CTEK told me that Mercedes is known for charging problems, means... you should connect the charger directly to the battery and not to the jump start ports. Still have to test this.

Thank you very much about you

It was cringe watching you do the battery replacement with your watch on lol good vid nonetheless 💪🏽

hi; I have a 2013 C300 4Matic, your video looks like this replacement is so easy, but how about losing data settings like radio, windows etc. how to reset those in an event or I should not worry about any of that for my model MB? please advice. thanks

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

does this work on c400?

I have a 2013 c350 and was told that the new batteries need to be programmed into the car, Is that true?

Is it a good idea to hook up battery terminals to a power pack whilst changing the battery to make sure there is a continuous loop of power thus saving any reset problems ? My battery needs cha going on. 20111 C300 and I’m terrified of reset issues . Help please?

Hi, I am looking at buying a W205 C250, and I noted that the red fuse tab/switch next to the battery is in the down position over the black. What could cause this? The car is salvage hence why I trying to be careful. Thanks for your help Kind regards.

I changed my battery in my c250 no problem ,now the interior lights do not come on automatically or off ,any ideas my friend ?

To keep the memory you should connect a 12v battery to neg and positive. Then the roof and windows would never lose the memory.

Do I need a memory saver ?? While replacing a battery on a w205 for 2018 ?

lol imagine my surprise when I looked at this as a guide and only realised after removing the cover that in RHD models they moved the battery to the other side

No programming? Cool!

I realized your rear window override button light stayed stuck on. How did you fix this?

Can you oneday try to change c class w205 licence plate led light?

Would this be the same process on a 2019 amg c43? (w205, m276 engine)

I got a question how do you organize it because I wanna build a Basically any Gera motors parts fun the early 2 thousands that's my dream in my life What should I do

I know that some BMW models require programming when changing batteries. Does Mercedes need that too? ​

If I went to AutoZone and told him year and model should the battery work

Thanks for sharing this great informative video on how to replace a battery. I currently own a 2014 C Class 300 that needs a new battery. Do you if any of the major retailers such as Auto Zone will do the installation as a courtesy if you purchase the battery from them ?

What group series better is good for 2015 c300 4 matic

I am not much of a German car person but I do like similar early 2 thousands Mercedes but I just wish there's a company that makes car parts for Cadillac the CTS D TSF TS

Hi dear ..i purchased c300 from usa ...eco options is not working eco auto on & off ..what the solution ..kindly advise

Don't you need a scan tool to reset the computer so that it does not overcharge the battery?

Does the car lose memory of reading settings, etc when you have the disconnected?

After changing the battery on my 2015 C300 it appears that the car doesn’t recognize my key fob. Is there anyone that has experience the same issue. It won’t start with the button or by actually insert the key. The dashboard lights up but no bell sound like normal operation. Thanks

Mercedes Benz dealership wanted $554 for me to pay for a replacement battery I rather just go but a battery from the auto part store and have someone put one in
