Mercedes ML350 Main Battery Replacement 

That was great. Very thorough. And thank you for the emphasis on the vent tube. Great call on the reminder and importance of it. Thank you!!

Thanks for the video-you helped me out again. One special note. When you move the passenger seat forward please please please ALSO raise the seat to the highest it can go. I forgot to raise the seat after I disconnected the battery and I didn't have clearance pull the battery out. I took a chance that putting jumper cables on the engine jumping terminals was able to give power to the seat to raise it up. Whew! battery came out with no problem then.

What I did was to remove the front passenger seat, without disconnecting the electrical, flipped it out on the passenger door and fully gain access to the battery. It might be longer this way but it certainly saved my back pain!

Thank you! I couldn't have done it without your help!

PS. The battery weighs 55lbs. The dealership will remove the seat and charge of course for extra labor. Watching you do the job with one hand while filming was impressive and I subscribed to your channel. One of the better videos esp. related to loosing settings which many other vlogs don’t explain well. Thanks!

Thank u so much for your video you are awesome! One piece of helpful information I think missed was that needing an extension for taking out the mounting bracket.

Thanks bruh... I have an ML550 and I just picked up a platinum Diehard battery that I need to install.

Very good instructions, thank you very much

hey Keith so I have key for my 2001 ML 350 ... by turning it off and leaving the driver side door open i'll be at zero status? I have seen other videos trickle

Job well done thanks.

Hi Keith firstly thank you for all your videos, I have 2007 GL with two problems First the battery white and red warnings are showing on the dash , Ive charged the battery, replaced the battery, replaced the alternator but still have the warnings, done your alternator test and the 12 volt is showing. Second when driving the rev counter fluctuates up and down constantly surging up and down. Can you suggest what I can do please. In idle no surge.. Thanking you in advance

Thank you very much.

Thanx for posting this. Now I feel confident about replacing my battery. While you’re there, should you replace the smaller battery as well?

Great vid 👍👍👍🫡🫡🫡🫡🫡

thank-you from Tennessee!!

Do you know if it use agm or normal lead acid originally ?

So after i changed my battery in my ml350, in noticed the fan turns on randomly, it the inner vents that are blowing, any idea as to what i can do to fix that?

would you know what would cause a overnight battery drain? so thinking that i had a bad battery i changed it and its still doing the same thing. problem started on Sunday.

Thank you!, we'll described! BTW, the gas from the battery is hydrogen, not poisonous, but explosive - found mine routed to the left into the car, probably done by the professional mechanic that changed the battery last time.....

What can you do when you lose your presets. I changed my battery and now it says 🆘 malfunction. My locks my trunk don’t close the blinkers don’t work. It drives great other than that. It wasn’t like that before the battery replacement

Nice

on the level...thanks!

Thanks for sharing, does these steps goes with all types of mercedes. Mine is W222 /2015

greetings from Poland👍

We're you running on backup battery? I have a obd 2 jumper and/or a backup booster battery to connect under the hood. What is keeping the memories intact, w/o a backup power supply of some sort, or is it not needed.?

Hey Keith this is Kevin Robertson from Las Vegas I got an ML350 2008 Mercedes is there a kill switch or a dead man poster to not start your car can you tell me where it's located

I have 2015 model , how did you preserve the configuration of the computer ? usually you will connect a battery infront ?

Hey there Keith! Thanks for all your postings. Just replaced main/aux batteries. Funny thing was that I thought the purchase at Batteries Plus would be cheaper but main was the same and for the aux, they wanted me to switch the terminals, i.e., black to red and red to black. So not thanks and went thru my local MB discount window from the web and ended up getting the main for same price and the aux for only $10 more. Sweet! Replacing was a PIA though. On my 2009 ML 350 4matic, the carpet not cut so close to front seat so needed more vigorous effort to get that heavy ass main out. Finally completed. ONE DIFFERENCE FOR ME: After completing, I put key into slot and turned to #2 position and display told me to REMOVE KEY. I followed instructions and watched clock above steering wheel rotate 12 hours and stop. I then inserted Key again and got same thing so did it again. Then everything when off and I put key in again, started car and the clock updated one more time to the correct time this time and all is now good. So appreciate your vids! Will

So if I want to trickle charge my battery, do I connect to the engine bay battery or the one underneath the seat? So why when I jump start my ML i always connect to engine bay battery?? what use is that battery for then? Thank you

the "poisonous gas" is hydrogen from the battery plates... it's highly explosive. Case in point Zeplin airship was filled with hydrogen! Txs Keith 👍

If I do exactly the same on my 2007/2008 gl450 you mean I would not lose my stereo memory? I mean the enter code thing...

Thank you very much for this wonderful review. I have a question, what battery type fits in Ml 2006? I need to buy a battery and I do not know what should I look for. Please help. Thank you very much again.

can you make a video please about how to set the tailgate height

Hello! New subbie here! I own the same model.. All dash lights work...wheel turns left & right.. radio even comes on but won't turn to start.... Any suggestions? I hope to hear from you!

Update: Did the job by myself on 2006 ML500 (W164). Open your manual and follow this video, did the job in 2 hrs but was very careful concerned about error codes. There are very specific procedures in order. Used a interstate battery (Costco $177) same battery that was in ML for last 9 years. It was a lot easier that I thought. One big tip! Get a magnet pen extender, you will loose bolts and makes it easy to grab plate holding battery in tray. Also when you replace vent tube do it before you put battery in through the rubber grommet and listen for a “click” as you push it through. My mechanic didn’t have it pushed deep enough last battery replacement. Only setting I have left to adjust is sunroof and need to find map for the fuses, again refer to manual. Saved $400 in labor. Much easier than I thought but do your research. Picked up my new 55lb beast today, now for the fun part. The dealership recommended removing the passenger seat on my ML500. I have experience removing the drivers side. Do you think with the size and weight of the battery it’s worth going through this process doing it as a one man job? With regards to keeping your settings for a W164 2006 ML 500 w/ tons of electronics how about hooking up a 12V to the under the hood battery terminals to keep electric settings. I have had previously experienced issues getting to zero b/4 w/ key technique. Thoughts?

Changed auxillary battery 06 r350 now car is not fireing up

how do i move the front passenger seat if i have a dead battery?

Great video but now my radio doesn't work right. Can you help me out, please? 2008 ml350 4matic. Love the vids!

Would you recommend hooking up a small external battery instead of $#@%! driver door ...business?

how come i can't lift the battery out even trying it your way?

about the Mercedes-Benz ML350

Stupid engineers. There is no good reason to make that batter compartment that hard to get to. "Idiot"is not publicly a acceptable term to say anymore. It's a shame that just because we can't say that anymore nothing has changed with engineers. They can design safety boots but wouldn't know how to pour pee our of one.

German engineers have a great reputation, but they have some stupid ideas. They don't seem to care much about ease of repair, and their cars aren't very reliable. Mini Coopers are really BMW's, and old ones sell for pennies because they're complete garbage. German tanks had better armor and bigger guns than Shermans, but they were hell to repair, they broke down a lot, and when they burned, no one could get out. A Sherman or T-34 that runs is better than 50 Panzers that don't. Right now, my buddy is in my driveway trying to get a battery out of a 2014 GL350. The access hole is way smaller than the one in this video. I think the seat will have to come out. Mercedes designed the car so female and elderly owners can't work on it. Only men who are properly pumped up like Hans and Franz. Not very nice.

what were mercedes thinking
