Battery OEM Volkswagen or OEM Mercedes

Update: it was just the battery, everything works fine after replacement and coding/adaptation. No error codes. Thanks everyone

Historically, OEM Mercedes batteries are really good and last many years.

Everyone's suggesting things that might save you half a percent or so, but no one has pointed out that by driving at 80mph, you lose *around 30% more battery* than if you were doing 70mph over the same distance

For my Mercedes sprinter I had the same battery in it for 10 years. I went and bought it at the dealership. Since the last one lasted 10 years. I shouldn’t have a problem with it.

wir haben unseren ID4 mit 50.000km gekauft und EZ 08/2023 sorich recht viel in kurzer Zeit geladen, da vorbesitzer ihn als Firmenwagen hatte. Beim Kauf war SoH vei 94% und die ersten Prozente degradieren ja schneller sprich je geringer SoH desto weniger degration. Weshalb ich auch behaupten möchte, der Akku hält länger als das Auto

I’ve had my id3 5 years now and had very few problems with the car or charging. I’ll get maybe 180 miles on the motorway but close to 240 miles cross country. Manchester to Sheffield to Nottingham and back to Manchester left me with around 50 miles range, but I can’t get from Manchester to London, or Manchester to Glasgow without charging.

I just preemptively changed my 2007 VW golf battery at 120k...I probably could have gone farther but every now and again I would get a weird code that likely was voltage relative.

On the day of delivery itself, the car wouldn\u2019t start. The dealership jump-started it and said there was a small battery issue, assuring me that it won\u2019t happen again. But from that day onwards, the vehicle has never been reliable.

I don’t have an AMG, but a 2024 CLA 200d and having battery drain problem is annoying to say the least and haven’t even had the car for a month when it all started happening. It’s been at the dealer for the past 3 days and no voltage drop there. They gave me the signal blocking key case and they upgraded the software and still can’t find the problem. Third visit in the month and new battery installed too.

same issue with daily driver 2021 E63. In this case though, the car doesnt give me a warning as much as the Mercedes app on my phone - it alerts to low battery -even critically low, but when I get into the car it starts and there is no message.
