- I just learned on this day that newer cars have two batteries. Technology has really amazed me.
2010 Mercedes ML 350 Auxiliary battery replacement. This really is something I learned different on this day. We really never stop learning...
We hope this video helps others out there with replacing their auxiliary battery. It was a challenge since the battery location had limited space to work at. Be careful not to injure yourself!

Love the tissue paper technique to hold the nut in the socket. Genius! I’m going to have to start using that.
And if you are eco-friendly, you can use a leaf! Lol! Use whatever is available on the spot, even a piece of newspaper. As long as you don’t forget to remove it from the battery area. We don’t want it starting a fire. Thank you for watching and subscribing! -Rjeff H2H

Thanks. I fought long and hard to get the battery up and out. Not an easy task.
After you replaced secondary battery, and then start the car was the white battery light gone?
Did you run into any issues after disconnecting and reconnecting both battery beyond radio codes. Anything you have to reset or re-program after re-installation with a OBD reader or computer. Or is it just plug-in play like most cars. I know for the S-class you have to re-calibrate some stuff.
Hello. I was asked just to replace the aux battery, and the owner never mentioned anything he needed reprogrammed/recalibrated afterwards. Sorry, I could not give you a better answer. Thanks-Rjeff H2H
I undo the front passenger seat four screws and push it forward. It gives you unrestricted access to the battery(ies) bay.
How do I know which screws that is to undo? And what tool do I need to be able to do this (not a mechanic! Lol)
badazz philipino mechanic thanks bro
Lol. Thanks for the compliment bro, you just made my day! Thank you for watching! 👍- Rjeff H2H
Nice! Should both batteries be replaced at the same time?
Hello. My opinion is just replace which one is bad. They operate independent from each other, so no sense in replacing if the other battery is still good. Hope that makes sense. Thank you for watching - Rjeff H2H
My wife has a 2020 GLB 250 are the batteries located in the same spot by chance, thanks in advance
Hello. The 2019-2020 GLB 250 auxiliary battery is located inside/under the center console. Front base of the shifter lever.
But I think you car is too young to have a bad aux battery. Check for blown fuses and/or wiring first. These batteries should last minimum of 6 years. Hope that helps. Thank you for watching! -Rjeff H2H
@@How2Helen thanks for reply! I’ll definitely check the fuses, car will not start due to bad battery definitely going to check when I get home
Do you lose the codes (radio) when you replace the main battery or the auxiliary battery, is there a way to save the codes. I don’t have the codes and the local dealer won’t work with me. Thank you
Hello. On our experience, we did not lose the radio codes. As you saw on the video, we had to remove the main battery, to get to the auxiliary battery. But I cannot guarantee if will have the same luck as we did. Sorry if that wasn’t much of a help. All I can do is wish you luck. I hope you have the same results as we did. Keep us posted!

I have just replaced the main battery and used many colourful words during the process, I was concerned about loosing coding so connected a battery charger to the pos and neg terminals under the bonnet without issues.
@@steverichardson6920 I know how you feel. They really make it a challenge just to change a battery. Maybe they did it that way so that whenever you do change your battery, you feel like you have made a big achievement and feel good about yourself. Lol.

How long does the original auxiliary battery suppose to last?
Hello. This was the original battery on the vehicle. And we replaced it in 2023. So from the owner’s experience, it lasted 13 years. But we don’t know if that is the average lifespan as this is the only one I have worked on so far. Thank you for watching! -Rjeff
How can you tell it needed to be replaced?
Hello. The battery light on the dash will be illuminated if yours need to be replaced, as seen on the first 4 seconds on the video. Is the battery light on you dash on? Let me know. Thank you for watching and subscribing -Rjeff H2H
