Marvelous video and super helpful! Thank you so much for making it!
Per WIS, remove the battery sensor on the negative terminal first before removing the negative terminal! Great video, thank you
KillerHERTZ
Great video! Exactly what I needed.
The same seemed to work on the moon roof.
Thanks for this, especially the electrical part.
Excellent vid as always
Super clear instructions and very helpful! Thanks!
You should disconnect the BEM-Sensor cable on the left side of the negative cable before attaching it back, the sparks could damage the sensor due to voltage spikes. After tightening the bolt, you can reattach it.
Very informative video as usual thanks for giving us the clue and saving us money too top man cheers 👍👊
Thank you for your help...very simple and practical....
Excellent explanation. Cheers
Excellent content and very helpful. Thank you very much for taking the time to walk us through to minimize or avoid the pain changing the main battery.
Excellent! Very appreciated here!
Excellent, no nonsense instructions clearly stated and presented!
Glad you enjoyed it!

That tip at the end about clearing warnings on dashboard!…I’ll admit I tried it with a lot of scepticism, but it worked!
I’m sure you have saved , not only me, but a lot of others heaps of money on garage bills👏🏼
"Hi Susan. I was a bit bored so I dismantled my Corby Trouser Press. I can't put it back together again. That would be me with a car battery! Nice video mate
Here in the states i replaced battery in my 2002 e320 and on the new battery there was no plug in for the hose thingie. Also when reconnecting the battery the alarm went off and finally figured out the key needs to be in the ignition first. Yours being a newer model i could see you didn't have that problem, must be on older models only i guess. Thanks for posting
Thank you mate. I have another problem with me car. Do you think the battery replacement had anything to do with the gear change. I have taken it to mercedes slough twice on different occasions with the gear problem and they said it had no issues with the gear. Instead they fixed the turbo pipe within the engine and a software update, they also mentioned that the gearbox mounting is also affecting it but I didn't get that changed as it was an £800 job and also didn't know if it would fix the problem. Could you help me what could be the issue so I can get it fixed. P. S I have already changed the gearbox oil. Thank you
Verry helpfull thanks,A specialy with the windows problem,again thanks.
w204 c200 cgi yb2011 / did it just like that , no problem at all ! /no further setups necessary even the time set up itself after ten minutes ride./ All settings just like before ! Great thanks for the video thanks to mercedes for the easy installation ! Refer to the manual , if insecure, it is described just like that !
Thanks. Very helpful
Excellent , thank you .
Super helpful. TY👍🏽
Excellent video. Most helpful. Thx
you are my spirit animal... you own the same car and same type of phone XD
Well explained. Constructive tip; fender cover and remove watch :)
A nice clear and concise video and then the confusion starts in the comments. You need to attach external power during the change...wait, no you don't. You need to reset the computer... wait, no you don't. The Merc forums are just as bad.
Great video 👍 when ever I purchase a car I always replace the battery/ies as I know from that moment I do this I'll have 4 years worry free concern about them. My 2006 CLS 320 cdi has 2 batteries the big main in the boot which I replaced with a Varta make I consider them very good reliable batteries, the 2nd smaller one same size as a motorbike battery is in the engine bay that runs the SBS system I highly recommend you purchase the Mercedes one I've found the aftermarket ones the terminals are the wrong size M6 bolts whereas the Mercedes one's are M8 bolts.
really good video, i'm about to do the same on my older bclass 2013 W246.
Thanks mate
Worth mentioning the adjustment on the bonnet strut to allow the bonnet to come back far enough to allow space to get the battery out easily.
Yep, as featured in my video here: ruclips.net/video/fC3srVStY9s/видео.html
We have an older Mercedes that when we replaced the battery, it will start, then shut off. So far our mechanic has not been able to fix this. It ran great before the battery replacement. Any ideas?
Great video!
Hi I have a 2002 E430. And my car wouldn't crank. So I went to buy another battery. I replaced the battery but now it won't start. What should I do? Hope you can help.
the days of British cars with 6Volts and positive chassis are not so old... it kept mechanics well busy 😅
how would i reset on a v220 2003 w368? battery was off overnight i know it can be reset from the key but not sure how?
Hi mate after disconnecting the battery and taking hours to start replacing it my car doesnt try to start and i get a error message electronic ignition lock and steering column module and ideas on how to solve this? Also windows wont move other than that everything else is normal
Any help would be appreciated thanks
Hi, Thanks for the video, would this be the same constraints with a older model, I have a 2004 S430, from what i researched so far, they say its a complex computer and must never loose power to the computer while the battery is being reset. Will you method work on my model of benz? Please let me know. Thanks
Hi, Yes it should work the same on any model, cheers :)
Thank you for your informative video. I want to ask you about a problem we are having in E300 (W213) 2018. The parking pilot and hold function sometimes work and sometimes not. We changed both the auxiliary battery and main battery and after the changes they work but in the next day the problem comes back. The dealership was of no help. They had the car for around 10 days and cost around $800 and they are not sure of the cause!
The parking function has been removed by MB in some countries due to Legal issues. possibly due to that.
Cant help re: Brake hold sorry
@@killerhertzmercedes Thank you very much for your reply. It is not removed here in Oman as it works fine with others and sometimes works fine with us. I will update this comment if the problem gets fixed for reference for people who might face the same issue.
was the new battery registered?
There are two vent holes on the battery - one with the tube and one with a cap on the opposite side. You need to plug the spare hole with the red cap from the old battery seen in 3:17.
The new battery had a black cap/plug in it already so didnt need it.
It depends on the make of battery whether or not it comes with a blanking plug. I’ve just replaced the battery in my C350 with a Bosch and it didn’t come with either breather hole plugged. If the end opposite where the breather pipe fits isn’t blocked there’s a risk of acid vapours escaping and eating into the battery holder.
I purchased the same brand of battery that you fitted. I phoned the supplier to ask about the spare hole opposite the breather hose and they stated that it MUST NOT be plugged at anytime. I am now totally confused.
What year is yours? It's about time to change my 2014 CLS550. Thank you so much for your video.
2011, should be the same
Hi great vid as usual thanks, have just changed steering wheels from an AMG unit back to a woodgrain unit on a 2013 E class and now have a message coming up saying RHS air bag Fault contact workshop? Any thoughts please?
The Airbags may not be fully compatable. If you have a scanning tool try and code it out. otherwise you might need to swap it back.
Thanks for the informative video, could you please help me to get the (P & ECO) functions working? I just replaced my auxiliary battery yesterday for my E220 night edition 2016, I can see the ECO became yellow instead of green and whenever I break I see the HOLD on but the engine keeps on, also the P and the parking arrows appears for the parking assist but they are not working, I was told that I might need to reset the computer but no idea how.
I look forward to hearing from you
Thanks
You need the main battery changing, not the Aux for the Eco functions. thanks.
FYI: ECO stands for "Engine Cut Off" there are many conditions that can upset its normal functioning. The engine PCM trys to evaluate tge condition of main AGM to make sure it can safely command a stop and the car will be able to restart after sitting under 30Amp. load then 100Amp burst for starter.
✌️
Hi, Can I do the same process with replacing in the new A class model w177?
Hi, yes it should be the same.
Hi do you recommend this battery: Varta Start-Stop Silver Dynamic AGM G14 12Volt 95Ah 850A/EN 595 901 085 Starter battery
For my W212 E63 AMG 2013 ?
Yes that should be fine :)
@@killerhertzmercedes hi mate hope you doing well! , so I bought the battery and will install it soon , my question is I don’t need to charge this battery? And my battery is what I mention above is AGM G14 , I see that is little bit different from what you installed on your cls63
Awesome! Prob with back right window, as you said; trick didn't work and now window all way down. Tried a couple of times. Other windows weren't affected. Any further advice?
disconnect again and try once again. sometimes it takes a few attempts
connect a battery charger to the terminals then you dont have to reset anything
The reason you have to reset it is so that’s the slight change in voltage from the old to new battery doesn’t fry sensitive relays
That doesn't reset the learning cycle for the charging system... Read up on how they work it's quite high tech the charging cycles and battery maintenance built into the intelligent charging system
hi I have a 2011 MB C300 I need to send in my key switch (EIS) to get programmed to a new key fob the company that will be programming the key switch (EIS) to a new key fob need my key switch (EIS) I need to disconnect my battery because I need to remove my key switch (EIS) for at least two weeks. Does any one know if I will have problems with all the computers on board this car being that the battery will be disconnected for that long as I heard that Mercedes cant be with out power for a log time. pleased help thanks to all in advance.
Hi could you please tell me which model you were replacing battery ie GLA 250 ! Thank you
Hi, the car was a CLS63 AMG, the battery details can be seen on screen. cheers
hi I have recently changed the battery in my mercedes c220 cdi w205 and now having issues with the boot will not open fully but will close ok how do i resolve this please
Just quoted $860 Australian to purchase a replacement battery for a200 with the 1.3T in it. That’s Mercedes dealer racket for you, it’s just a Varta 70 A/hr 720 cca.
Found exactly the same battery for $450 , didn’t have the Mercedes sticker on the side…. I guess that’s worth $400 + .
Bastards!
You bet!!!
2014 E350c. Getting oddball electrical problems. Totally random. Has started to act like it will start, guages come on, but won't crank.
May do that once, then start, or it may take a random number or tries to start.
The brackets that pull the seatbelts out of the way extended. Driver side retracted, passenger side will not.
Is it potentially a low battery?
Almost certainly, try testing the voltage of the battery before doing anything.
Check my HowTo videos for resetting the Service Menu (for whichever is applicable for your car) to access the voltage on the dash screen.
How can I switch off the w203 alarm when I try to re-connect the negative pol of a new battery? It makes really loud alarm.
Try leaving key in the ignition
I think it is worth mentioning that I've seen a couple of other videos on changing the main battery and some say to first apply a fresh battery or a battery charger/jump starter to the jump terminals near the battery.
This way the car's main computer never loses power and you don't have to worry about all the programming issues. So + terminal slider in front of the main battery gets the positive from your outside power source and then ground - to some metal in the engine compartment.
THEN unhook your main batteries terminals.
I have not done this but I am about to since my battery is near dead.
Has anyone else done this?
I've not seen a video about it, but I have read several comments below other videos saying this is the way to do it and the way the dealer's do it. They are lazy and don't want to do any programming so I think this may be valid.
As long as you swap it over within 30mins you should be fine as it will remember all the settings.
Hi. My 2011 c250. Was repairing a common tail light fault with the negative wire. Everything wad fine. Motor, no problem. But at one point doors and boot open too long. Running the battery down. Charged up battery. All bells and whistles. But motor won’t turn over. Just hear a click. Is there something I need to reset under the hood to re activate relays or ecu. If there is, actual location would be much appreciated.
Regards KevinM
Did you ever figure out the problem? I have the same problem and 😮
Hi, I have a 2015 CLS AMG 63 S Shooting Brake 5.5 Automatic Petrol. The battery has gone flat a few times, but now OK, but some of the functions, Start Stop, Auto Lights have stopped. Do you know how to reset them, please?
They all sound symptoms of a failing/failed Aux battery. please check my other video (also filmed with a CLS).
I have a problem with tilt wheel after replacing the batteries (2), I hear switch and motor but no tilt up or down. :O~
Please.could you show the removal and replacement of the battery in modelB180CDI. 2009.thank you
I dont have a B class - it should be virtually identical to this video however.
I have 2013 E350 4Matic. I got my battery replaced few months ago and this issue started. The front passenger side window button when hold up, the window rolls down, and when hold down, the window rolls up and doesn't go all the way up.
1. I put my keys in all the way clockwise to on position with the engine not running.
2. lift up the switch all the way up to second click and hold it for 30 seconds
3. lift down the switch all the way down to second click and hold it for 30 seconds.
This is not working. Any suggestions?
Disconnect the battery again for 5 mins and try the process once again.
Was the memory and setting reset to default once disconnected?does MB has internal built in battery to back up those?
Depends upon the age of the car, all models from the past 10 years or so should save the settings for around 30mins.

Hi, very new to this platform got problem with my Mercedes e220 2015 . While driving back home last night initially message appeared on dash: battery sign and see owner manual. I stop for fuel and start the car again message didn't come for 1st 5 miles but then it came back but 2 miles away from home message changed to stop Vehicle with battery sign. Anyone have idea what that mean ? Is it the end of battery life as my car is now not starting shows voltage 9.3V
Thanks In Advance
9.3 V is too low for a car battery...your car is going to die on you...I'm thinking either the alternator is not charging or the battery is bad. Have your battery system & charging system checked out asap.
Very helpful. Question: I lost my navi module after replacing the battery. How can this be reinstalled?
Hi, how do you mean lost it sorry?
@@killerhertzmercedes when I press the navi button it says no navigation module connected. This happened after the car battery was replaced. It is a 2014 C250.
@@barbiemoss7189odd. it might have fused. If you connect it up to a diagnostic machine it should tell you.
Yes definitely remove the earth terminal first, and reconnect it last, but that is because if you work in the 12v terminal first and your spanner, socket or whatever should happen to touch any other metalwork there will be a large arc which could explode the battery if there are battery gases in the vicinity. Nothing to do with getting an electrical shock.
Do these battery's need to be programmed in 2014 c250 models
@@Dabbyalien Looking around it seems that MB don't generally need to be programmed for a replacement battery ... but some may, The best thing you can do is find a forum for your model and year and ask there.
a good ru;e of the thumb: if you are taking away thats a negative, negative first. if you are adding, thats a positive, positive first. pretty simple to remember..
@@ST-lb8wp Completely misses the point that some cars are still positive earth and on those it is the positive that has to be removed first. Hence the 'simple' thing of always removing the earth first and replacing it last.
@@paulhunt5873 Are you fn kidding me? By reading all the posts it generally seems people are have having problems...ugh Takes a village... Register the damn battery people! FOXWELL NT510
You won't get a shock by touching the positive terminal. The reason for disconnecting the negative first is to eliminate the risk of shorting the battery positive to the metalwork with the tool.
Great video, thank you.
Hi all. I have a 2015 mercedes e class diesel and it needs a new battery. I will be replacing it soon with another AGM one as thats what was factory fitted. so will it need coding so the car knows a new battery is fitted. I also have the Icarsoft CR MAX scan tool and mercedes is not an option in manufacturers list for registering batteries. Any advice or help would be great please as googling keeps bringing up mixed results. Thanks
You shouldnt need to register it/inform the car has a new battery.
Ok thanks for the reply
My 2018 cla 250 battery was failing and prior to me changing battery I put down the passenger and the back passenger window. Now with a new battery I cant seem to get those 2 windows to go back up. Any fix?
Have you tried the window reset fix on the actual window switches themselves? not from the drivers switch bank?
I hear the windows in question click however the windows do not go back up.
@@itschriselement you need to follow the reset process as per the video
How about placing the car on life support so you won't loose the computer memory in the first place, you can place a power supply like a jump starter to the jump points as you remove the terminal and replace the battery. It will act as redundancy and will make the replacement very convenient.
Wow really?!!! Thanks
I saw another post about this too. He said that you should hook up another 12V battery to the jumper + terminal and then a piece of metal in the engine compartment first, and THEN unhook the terminals from the old battery you are replacing. This makes sense to me and this way the car's main computer does not loose power during the entire process and you don't have to worry about all the programming crap.
I've not done this or confirmed it, but I need a new battery ASAP so I guess I'm going to find out.
Sounds good !!!
some cars have auxiliary battery. is it necessary to do this external jumper connection while having the aux battery to prevent loosing data? i am asking because i really don't know the function of the aux battery.
@@yalcinarik I have not been able to confirm this, but I was told that the smaller battery in the trunk, aux battery, if for the stop/start feature of the car. I don't think that is entirely true since as my main battery got low, the stop/start feature shut itself off. When I replaced my main battery last week I just left a charger connected to the jumper terminals near the battery. I don't know if the aux battery will keep everything alive while you change the main unit, but I suspect it will. I had the charger and I just didn't want to hassle with having to go to the dealer if anything went wrong.
Can you please help me? After replacing 2014 ML350 main battery, everything was normal. 2 months down the line, now I am starting to get all kinds of electrical messages that last 24 hrs then onto something new- check engine, lights turn on by themselves, asks to replace key fob battery and the latest my stereo is in continuous rebooting loop!! Is it the wrong main battery? Is it my auxiliary battery? Is it the fuse box? Was there a re-set sequence I should have done? My mechanic isn't able to help
First up, swap the main battery with another just to see if the issues still occur (ask your mechanic to do this in his shop) then if it still doesnt work, remove it and the Aux for 20mins or so, reconnect to see if it fixes it.
If not, you are going to need to get it attached to a diagnostic machine.
@@killerhertzmercedes Will do.. Thank you so much
@@killerhertzmercedes Mechanic still stumped. Screen/radio/console works at speed of 50kmh but reboots or shuts down at higher or lower speeds. This must be a battery issue no?
There was a reset sequence you should have done. Its called registering the battery. The computer doesnt know there is a new battery. So it is still telling the alternator to charge it like an old battery with too much amperage. It needs to know there is a fresh healthy battery so it doesnt charge it as much. Instead its overcharging the new battery, giving it a shorter life. Its a sickened battery now and cant hold a charge,and that is jacking up electronic systems ... the Foxwell NT510 code reader is Mercedes Benz fitted. It has the function to register your battery and a crapload of other stuff. not very expensive either. Doing this will make your battery last very long.
Just watched the video, can someone tell me if you need to code the new battery, I've been told you need it coded to reset the BMS. I'd hoped you could swap the batteries over as per the video
Depends on the model, but for the most part you shouldnt need to.
Why with a new battery my ml350 2014 starts and then doesn’t.
Great video, just done mine on my 2012 c250cdi. Any idea why I now have an airbag/ restraint system malfunction and how to clear it? Happened as soon as I power the car back up with the new battery installed. Everything else works fine.
Possibly the yellow pin connector under ether front seat as come loose and has triggered it, you will need to get it onto a diagnostic machine to tell you for sure/clear the error.
@@killerhertzmercedes many thanks for the reply, I shall investigate. Cheers
@@tonygarlingewarren7456 I have the same issue with my 2012 C200 CDI. Did you resolve your issue and how?
Try resetting your steering wheel. As per video. Move all way to one side. Hold for 5 secs and then to the other side and repeat.
@@killerhertzmercedes Thanks for this, tried it but no joy unfortunately. Tried then switching the car off after doing this and turning it back on but same error appears. Might just require a diagnostics to clear.
Pls assist we fitted a new battery but the car is not starting. It goes like it starting but does not complete the start process. The keys are locking & opening but the mirrors do not close, they remain open
Possibly fault with alternator or starter motor, you need to get it on a Diagnostic machine.
@@killerhertzmercedes will do, thank you
Hy! I have to do this operation soon. My mechanic said that after all you presented , I should reset also the car ecu and “tell” the car that it has a new battery via MB Star. Is it true? Have you heard about this? If not, did you had any problems since you changed the battery? Thank you.
Hi, you shouldnt have any more issues that mentioned at the end of the video, Windows/Steering etc :)

My R500 went into limp mode after low voltage from a weak battery.I have since replaced with an agm group 49 battery as required but the battery warning light on,it starts but It is still in limp mode .Scanned it and got a code P0748 how can I reset or clear it ?
Ratchet of what size do I need? 1/4 or 3/8?
10mm Socket
you CANNOT get an electric shock from 12 volts. even if you see sparks when you connect jumper cables, something different is happening.

How do you re-learn the automatic folding mirrors?
If you check the convienence menu, should be an option to re-activate auto fold when locking/unlocking. cheers
Worth mentioning you have to reset the BMS system. Telling the car to wipe its data on the battery and to analyse the new battery. The temp sensor on the neg terminal. The resistance. The voltage drop, etc, etc
Any instructions on how to do that? My fan keeps running after replacing the battery and it seems to be thinking it’s the old battery and needs to be reset.
@@bycnwynn8346 your best bet is this. Call Mercedes and ask them to reset it. If they say sure and begin to book you in, that suggests they can do it. Because so far. My £5000 Autel diagnosis tool cant. My £3500 tool cant. Icarsoft who makes mb scanner say they cant get the software, and Yuasas battery config tool also cant do it.

@@jamesbarratt593 So were you able to reset the BMS system? I am about to change the rear (consumer) battery in a 2005 SL55.
*BACKGROUND
My car ( Mercedes CLK) has a relatively new battery, if I don't use the car for a week or two, the car has problems to start, more time left= more difficult to start.
*PROBLEM
Recently even if I'm driving the car each 3, 4 days, each time it gets weaker and weaker even if I drive for a long distance, I thought that the problem was the alternator but once the car starts the voltage is always over 14V.
* EXAMPLE
Yesterday I checked the voltage and boosted my car : once I connected the booster the voltage was 12.85 once I started the ignition drops to 6.15 V with the booster connected and yes! the car didn't start.
I can use the car but always once I stop the engine, need to be boosted even if I stop the engine for a second last but not least, now when I connect the booster first the positive and then the negative sparks come out ( positive with positive, negative with negative)
Please any help will be greatly appreciate
Thank you very much for your time and well- appreciated advice!
You really need to get an auto electrian to have a good look at it, something is drawing power and until you address this, the problem will remain...

I doubt you could get a ‘ nasty’ shock from touching the positive post of battery, surly he is not serious?
Glad you enjoyed the video and found it useful
Ive took the battery off my merc slk 250 and never had to reset anything
Be careful people if you accidentaly touch the terminals you will explode due to too high voltage!
I heard that some Benz may have a Battery Management System (BMS) which needs to be set to know that a new battery has been installed. Can this be done without going to the dealer?
I'd like to know the answer to this as well.
After researching a bit more, I see lots of people who exchange their batteries themselves and don't do any reset, and they've never noticed any strange behavior. Furthermore, there are handheld diagnostic devices that are MBZ specific that can be used to DIY reset the BMS after installation of a new battery (they cost about 50 USD). It looks like it's nothing more than going to the correct menus and pushing a few buttons. After recently having my battery tested as well as looking through an old repair order for battery replacement in my GLA 45 AMG, it appears from the dealer notes that all they do is this simple counter reset. Others online have noted the same. It's just a matter of "registering" the new battery with the system so that it can charge a bit more aggressively as the battery ages, from what I understand.
After changing battery i have inoperative light ...
I'm getting the battery light?after replacing the battery?
How long has the new battery been sat around not being used? - it will need 'charging', go for a 30min drive etc

Shouldnt be an issue on a modern car.
03:01 tightening *wink*
2:00 'give yourself a nasty shock'? Seriously? We are talking 12V here. Good practice dictates that we disconnect the negative terminal first so that we are not dealing with a spanner which is live with respect to the vehicle chassis.
