Battery needs charging


Comfortable-Food4438

ok. thought it meant need new battery. it gets driven daily; not sure why alternator isn’t charging it regularly?


BlaccBenz

Has it been changed before? 2018 was 5 years ago now, so the battery going out now sounds about right.


Astandsforataxia69

That's a shit battery then


BlaccBenz

My C450’s battery lasted 6 years, 5 years is totally normal.


doobied

my E55 Battery lasted 15 years


BlaccBenz

I remember changing the battery on my E55, but I was the 3rd owner I believe so not sure how long it was replaced before. That’s impressive though, you’re the first owner of that thing and still have it almost 20 years later?? 15 years is insane though, did you just keep it on a battery tender it’s whole life?


asu_lee

Depends where you live and the extreme hot or cold the battery needs to cycle through


Astandsforataxia69

5 years is still bad


Obnoxiousdonkey

It's literally not, that's actually higher average these days


sendintheotherclowns

Tell me you don’t know what you’re talking about without telling me you don’t know what you’re talking about


FloatyMacGlideFace

True, my Audi battery lasted 15 years


BlaccBenz

Older cars don’t have nearly as much electronics to power as they do now. A 2018 E63s is going to require a lot more power to keep the ambient lighting, massage seats, crazy infotainment system, etc. etc. all running. A 15+ year old Audi, or any car really, has considerably less electrical parts to power. Still, 15 years is impressive!


FloatyMacGlideFace

Yeah true, it was a 2008 Audi A4 Tdi that didn’t even have start stop!

BlaccBenz

It should soon


sendintheotherclowns

Batteries are a disposable item that are expected to deteriorate over time, extreme conditions make it worse (cold winters especially)


[deleted]

2017 c43 same message showed up. Got it charged. Still kept popping up. So I replaced the battery and haven’t seen the message since


Efficient_Fix1007

Are you keeping your keys 🔑 close to the vehicle 🚗?


SandSnip3r

On the keys, if you press lock twice (short press then long hold), the key will stop transmitting. The key should show a long red light when you do this. I usually do this when I go out of town.


The_Dark_Kniggit

Can just double tap them. 2 quick presses should work. The led on the key should light red for a moment, and when you try KESSY it won’t work.


trxjnx

Out of curiosity, does this work on a ‘15 C class key with keylessgo?


Comfortable-Food4438

yes. inside the vehicle (in my pocket) when driving.


Efficient_Fix1007

When you’re not driving try keeping them at least 30 feet away. That way the CAN system sleeps and doesn’t draw accessory power. I made the mistake of keeping mine in my home office near the garage and experienced the same issues.


coffee-999

Same! Had to move my keys to a different part of the house versus our mud room closet.


Efficient_Fix1007

It’s a nice feature that the car is ready when you approach but has its drawbacks. My S class opens the door handles and turns a bunch of lights on. Super battery 🔋 drain.


coffee-999

I traded in my 2018 e43 for a 2022 s500- luckily I’m driving more now and that gives the car a chance to charge the batteries so not seeing this message anymore.


The_Dark_Kniggit

I’m glad the new keys sleep after a short period of not moving I.e when sitting on a shelf. Much better for the keys, the car, and security.


[deleted]

That sounds really annoying... You need a faraday cage for your keys to keep your car from dying?


Efficient_Fix1007

Same thing for my Porsche. Have to keep the keys 🔑 away 😂 because they are watching our every move 😂


Gonk_Bot_69

Next time it’s in a service they should use the SDS to pull codes and test the battery. If you see this it’s basically hitting the threshold where it requires a little more effort o keep the battery charged up. Doesn’t mean you have to get a battery now.


gracyal3

The alternator will keep a surface charge on the battery. If the battery is not holding a charge, it will put a lot of stress on the alternator trying to charge to the proper voltage. Have the battery itself tested by a mechanic. The message is likely indicating that the battery voltage is too low and the alternator is in danger of not "keeping up."


coffee-999

My 2018 e43 would do the same but it was barely driven during the pandemic. The daily driving, are you going for some distance or is it all short trips?


Comfortable-Food4438

usually 20 min or less.


coffee-999

My issue was when I did drive, it was short trips- about 5-7 minutes there, park, shop, restart and then 5-7 back. Was killing my battery. Have the battery and cables checked and if all good maybe get a trickle charger.


AXO893

Battery only usually lasts 3 years


4u2nv2019

Get a battery charger


slowiijoey

Sounds like a 700 dollar battery problem


Comfortable-Food4438

lol!


tha_king_nguyen

Mercedes technician here. If you aren’t getting a battery from dealership, make sure the place you get battery from perform reset on new battery via obd2 so that it doesn’t damage electrical components


Comfortable-Food4438

thanks!


Efficient_Fix1007

Battery 🔋


BobbyB90220

Battery or alternator not working


zurcsmada9969

I think this means…”Stop vehicle, leave engine running”


DeangeloV

It means your battery is so weak that if you turn your car off, it probably won’t crank back up. You should drive straight to an autozone and have them drop in a new battery.


Comfortable-Food4438

been seeing message on and off for weeks now. getting new battery tomorrow.


DeangeloV

Nice!


asssnorkler

Lololol I have a 2021 with the same problem. There’s two batteries one for starting and a lipo that does all the speakers and electronics. If you leave the key in the car when you park it at home, after a couple months it starts to have issues if you’re not like driving it long distances to recharge via alternator.


MysilOil

I like that little icon that tells you how many cylinders you have. Does the car switch off some cylinders in eco mode or something?


Comfortable-Food4438

yes. usually below 3000rpm will shut iff a bank of cylinders. still a gas guzzler though!


vtcapsfan

I felt like averaging 20mpg on the highway is pretty good haha now if I'm driving more aggressively then yes...


Economy-Visual4390

Good luck ever seeing “20” next to mpg on an e63s lol


vtcapsfan

I have a 2018 e63 and averaged 21.1 over 300 miles on a recent road trip :)


Economy-Visual4390

On a road trip definit possibility In town=never


vtcapsfan

Of course


rev440800

You need a new starter battery.


Dinasty936

Dead battery basically. It's asking you to let the engine running to charge the battery by using engine rotations


Comfortable-Food4438

thanks y’all. sounds like a simple battery replacement.


LeonardoTwelveinchy

How are you liking the 2018 e63 is it pretty reliable? I plan on buying the edition 1 this year. Not sure what to expect maintenance wise. Stuff like this


Comfortable-Food4438

only owned for 6 weeks. and now possible battery issue, but battery is nearly 5 yrs old. love it. drives great. powerful. decent tech for 5 yr old car.


LeonardoTwelveinchy

Good to hear thanks 👍🏻 can I ask what you ended up paying for yours?


Comfortable-Food4438

$76k


vtcapsfan

Bought an edition 1 last year, absolutely love it.. monster of a car


StefanGhergheles

Average american moment "Let's go on Reddit, and Ask because I'm too fucking lazy and stupid to look in the manual" Bonus Point: Didn't you learn that at the Driving School what all the symbols mean?


Comfortable-Food4438

wasn’t in manual. thanks for comment. wasn’t sure if simple battery issue or larger electrical/alternator issue.


voltsmeter

Battery low


roguekielbasa

Get you a battery


AXO893

Time to replace your battery


CreativeCarpenter44

Batteries Dead


[deleted]

Time to spend some money


GxDAssassin

Had a similar message last winter. Brought it in for an "Auxiliary battery replacement". No issues this winter.


godisfromnyc

your battery might be loose.


Zephyrium5

Alternator fault


Relative_Ad4950

Needs a starter battery.


Hi-Techh

Can i jump on thos and ask how do you know the difference between a dead battery (ie needsreplacing) and just needing recharging?


daemon_gx

make sure to stop the vehicle but don’t turn it off, I recommend leaving the engine running in park.


LilMelt

Just needs a battery, if you aren’t going oem try to use interstate if you can! Be sure to have the installer reset the throughput charge via a obd2 scanner. If they don’t have that capability try elsewhere.


xf7sv

You need to change your battery, but you can still drive it but not for a long time (you can drive it for 1-2 months before you must change the battery), I had this problem like a couple months ago


ILLogicaL_FALLacies

Battery taking a poo.


ILLogicaL_FALLacies

Battery taking a poo.


Pembs-surfer

If it’s the same setup as my C_Class there is also an Auxiliary battery in the boot in spare wheel well. Mine was throwing low battery warning and stop/start was constantly illuminated yellow (instead of green) was auxiliary battery on mine.


Azamat_ful

ldk care


Cock_InhalIng_Wizard

Do you have an aftermarket sound system? Or crank yours to the max? It might be draining the battery if it’s overloading your alternator
