Mercedes Benz GLK350 auxiliary battery replacement detailed tips by froggy

[@cherylbrown8531]

I am a 70 year old woman who has never attended anything mechanical. His directions were spot on. I even purchased the same battery. Though it took me almost an hour I got it snow and saved $240.00.

[@cherylbrown8531]

Oops.....meant....I got it done.

[@1947froggy]

You are awesome Cheryl!

[@StacyFisher-s4u]

Wow

[@beem6792]

Well done. I’m 42 will give is go this weekend

[@StacyFisher-s4u]

You are very smart sir and I was just in the process to see if it just needed charged or a new battery

[@christophercalle2888]

Followed along and replaced my battery with ease. Thanks, Froggy! 🐸🙌

[@Kunal_Sampat]

Thanks a lot for his video. Was able to replace the auxiliary battery successfully. I got the original Mercedes battery which cost is $197 (not cheap) and followed your video to install it. Thank you! The plastic components in the back could have been designed differently 😊

[@1947froggy]

Glad to help!

Thanks for the vote of confidence getting that cover panel out...everything worked out great!

[@gabberzabber1962]

Awesome! Thank you sir!

[@racerboy2212]

The message says, “AUXILIARY BATTERY MALFUNCTION” Thanks for posting, this really helped. One thing to know, certain electronic functions will not work when that battery fails…..like Cruise Control!

[@1947froggy]

Thanks

Will this battery mess with transmission if bad. Like going in gear

[@racerboy2212]

Thanks for the video It helped me to find it quickly Likewise any feedback after changing the battery with a different brand .Are there changes in the running condition of the car.will a different brand do the job ?as long as it has the same Amp hour rating .Thanks

[@jimpurpura9868]

Great video, not too long. I have a 2014 GLK with original batteries. Would you advise changing both?

[@1947froggy]

Usually a dying battery gives you a warning "hard/slow starting" I usually wait for the warning, but if you are especially wary of "getting stuck" somewhere, it's not a bad idea for the engine battery. The car WILL RUN with a low aux battery & IIRC there is a dash warning, so really no need to go early on the aux.

[@beem6792]

I was advised to use motorcycle terminal nuts is that okay?

[@JRHZ28]

Wifes GLK is 2014. Factory battery lasted 5 years. Purchased "Chrome" brand battery from A-zon and replaced. Lasted 5 years as well. I replaced again today with same "chrome" brand. Hope it lasts 5 years also. Not sure why GLK says theres a problem because the old battery seems fine. Holds charge, reads 13 volts and operates the hatchback just fine.

[@1947froggy]

I think when the computer reads a voltage "on the margin" it sends a msg to replace (even if all seems fine) Every 5 yrs is not too bad. :)

[@joemckendree4547]

Hey Froggy, Joe M. here. I'm not sure about Mercedes, but i can tell you from multiple experiences in the past, (GM master tech), in a GM car if you use a regular flooded battery in place of the AGM battery in the auxiliary position it WILL set DTC's. This is primarily due to the battery's chemistry and the charging algorithm the ECM uses, (AGM vs. Flooded). Again, i'm not 100% on how Mercedes handles it, but i definitely know how GM does it. Hopefully, all will be well with it. Just something to be aware of. Great channel

[@1947froggy]

From what I can tell both are agm, thanks Joe!

[@jhmcglynn]

Ok, I’ll bite. What’s a DTC? 😀

[@jensc38]

170A (EN) is the engage current AFTER eco stop/start. It is important that the new battery is not less the specs on the original battery. I replaced mine with an Exide EK131 12v/13A/200A engage current.

[@1947froggy]

Thanks, this one has been perfect since installed.

[@StacyFisher-s4u]

I want to do exactly as you did so I need your help sir

[@jhmcglynn]

My 2015 Mercedes GLK 350 displayed “Auxiliary Battery Malfunction “ message this morning. I was not able to find any reference to that message in the owners manual. I had the dealer replace the main battery a couple of months ago and he mentioned I might be getting the auxiliary battery message soon. I’ll t4y to replace it myself.

[@1947froggy]

Just follow the video, it's not hard, take your time. :)

Does a GLS has an Auxiliary battery and where is it located

[@jnealeigh]

After replacing the battery is there anything else needed to reset on the computer of the car?

[@1947froggy]

Not that I recall, you will get a msg if so.

[@jerrbear6162]

Thanks so much, used the same battery you did. I stuck a flat screwdriver under the nut in the battery terminal to lift it up so the bolt would engage . I also had to cut the positive terminal cover with a razor knife to make it fit. Easy peasy, do it yourself!

[@1947froggy]

Mine still good. :)

[@ronnronn55]

I use a piece of small diameter tubing to lift the battery nut while reconnecting the terminals.

[@jerrywhite5421]

I just replaced mine and it is very easy to remove the trim piece at the rear of the vehicle. Apply light pressure and the clips holding it in place will Release. So much easier than getting frustrated trying to wiggle the battery cover out. .The nuts are 10mm and the Torx is 45. Also, this 15 minute video should be half the length. A lot of hemming and hawing about the sunlight, etc. etc. You MUST use the same type of battery technology, that is an AGM battery.

[@1947froggy]

Thanks for the tip on the trim piece, if you watch the video I did remove it. this battery doing great months later. Find shorter videos, no problem from me. :)

Always disconnect negative cable first the positive, then install positive then negative.

[@1947froggy]

Let me give you an example, say you disconnect neg first, then accidentally touch that negative to a ground on the car. What do you get? Right, sparkler! :) Don't believe, try it. :)

[@1947froggy]

Warning some folks are posting fake info in the comments, this IS an AGM battery been a year as I write this zero codes. Be careful of "keyboard experts". Battery #ad amzn.to/3hzxtzo

[@bnoakes4899]

I have a 2011 GLK auxillary battery, what does it do

[@1947froggy]

Auxiliary batteries work with your main starter battery, and as a backup battery in the event the main battery becomes disabled. It prevents your vehicle's electrical components from dropping when starting/stopping your engine and keeps your radio, GPS, and other in-vehicle electrical components turned on.

[@bnoakes4899]

@@1947froggy Ok will it have any affect on starting/

[@1947froggy]

@@bnoakes4899 Not sure but I don't believe a battery that size would start the car, doubt it. It's just as stated.

@@keyztothecityentertainment likely due to alternator - you battery isnt being recharged. Take multimeter- measure voltage when the engine is off. Then turn the engine on and check the voltage- it should show around 14v. If not showing around 14v, then your alternator is bad or belt running it. PS in addition, it could be draining from something using the power when the engine is turned off - someone mentioned it above
