I'll be using your vid as reference when I change my battery this week. The ignition battery lasted 10 yrs since I bought the car. When you're not using the car for a long time, run a trickle charger and that beast of a battery (AGMs) will live longer than 4 years. Thank you for posting this.
Man your video saved me today 🙌🏾. Real talk you saved me a ton of time and worry with your detailed video. It was raining 🌧 on me while I was working so I thoroughly appreciated the socket size information as well. 💪🏾👍🏽
Thanks, after replacing my battery I thought I would add this... 4:00 pulling that forward about three inches will unclip the top section and give enough access to get the battery out and room to remove/reinstall the bolt and clip which holds the battery down. Just keep wiggling that negative cable eventually it will come out that was the hardest part for me...
@@ningliu8185 I just pulled the battery forward and the mass of the battery unclipped the top two tabs an spread open the box the battery was sitting in. Then I lifted it out of the enlarged opening using the handle on the battery. The new battery went in through the same opening once seated I closed the box opening by inserting the tabs the corresponding slots and locking the box into the original position
@@ericfraser7543 Thanks a lot, Eric! I was able to replace the battery without removing the plastic box, but then I couldn’t reinstall the side metal piece. I guess I have to unclip the box by pulling the battery forward like you said. That’s the only way to reinstall the metal piece.
If you’re looking for the exact fitment as the OEM for your 2015 CLA 250 this is the battery to get. DieHard Platinum AGM Battery, Group Size H7, (850 CCA/ 80.0 AH/140 min reserve capacity )
Question? Do I need to reset after changing new battery. If not,I can do it my self. If reset required than I have to take to mercedes dear and it would be very expensive and I don't wanted that. Help please. Thanks.
my engine light is on with a code P0562 (system voltage low) after replacing the main battery. The new battery voltage is above 13V. With engine on, the voltage is above 14V. Engine starts normal. I tried to erase the code with my old scanner, but it would not clear. Everything is working normally. Do I need a mercedes scanner to reset?
...but wait --- how do you know if it's the big battery or the auxiliary battery inside the car under the carpet on passenger side THAT needs to be replaced 😭😭😭 Should I just replace BOTH?
If your car doesn’t start it’s the main car battery under the hood. If your having interior electrical issues it’s the auxiliary battery. I’d recommend replacing both that way you don’t have to constantly replacing each on different years.
Everybody forgets to mention that mercedes batteries typically need to be registered with your pcm to have proper communication. Otherwise you can have engine, trans and other issues.
thank you good sir, just changed my battery based on your video. Very much appreciated.

Can you elaborate how you unclipped the plastic thing around the battery? Thanks!!

@@ericfraser7543 I just tried really hard and still couldn't unclip the plastic box. It is too stubborn..
Did you have to reprogram it after installing the battery?
Thank you so much my car is doing the exact same thing!
Did you notice the car shifting a little funny as the battery was dying? That trunk pop safety was a trip 😂😂
Thanks for your video was very helpful.

There's actually an alternative battery for the eco/start / stop feature but the rest your right about
Negative off first on last and always run a terminal cleaner on the new battery
do you need an extra 12 volt battery attached to the battery terminals before removing the battery to prevent computer from resetting? Thanks.
No you don’t
@@lf82301 thank you
Great stepped instructions, Sir; thanks for sharing.
Does it need to be reprogrammed after changing starter battery???
my engine light is on with a code P0562 (system voltage low) after replacing the main battery. The new battery voltage is above 13V. With engine on, the voltage is above 14V. Engine starts normal. I tried to erase the code with my old scanner, but it would not clear. Everything is working normally. Do I need a mercedes scanner to reset?
Check the auxiliary battery. Did you check the voltage of the old one?
My trunk doing the same think and it won’t start ima replace the battery rnow I swapped the auxiliary battery and key fob battery
Good job. Helped me out alot.
So you had the same issue where if you stoped the car with the auto start stop on it just wouldn’t turn back on?
I’m having these problems and I replace the main battery 2 months ago
And aux battery like 1 year ago.
Is there anything else that can be?
My top clamp on the ( - ve ) is really tight any suggesting on how to get it loose without damaging the port?
Great information and thanks 😊
Is that the same size for a 2016 cla 250??
Good work!! Thank you!
...but wait --- how do you know if it's the big battery or the auxiliary battery inside the car under the carpet on passenger side THAT needs to be replaced 😭😭😭 Should I just replace BOTH?

It will give you an error on the dashboard for the auxiliary battery
My vent tube fell off and I have no idea where it goes to as far as the end that goes to my car? Can anyone help?!?
Starts at 3:46
Tools required: 10mm and 13mm wrench, extension recommended

U don’t need to for the 1st gen CLA 250
That’s not the auxiliary battery, the auxiliary battery is the one on front of passenger seat.
Ridicule, on ne voit rien
My battery died at 61k
Mine died at 52k, but that's 5 years so a pretty good battery life
60K! 😭
Mine at 45k
Mine at 27k 😅 (5 years)
Mine made its to 8 years with the original battery 86,000 miles 😱
Horrible video man but thanks anyway
