Battery OEM Hyundai or OEM Mercedes
Schedule the car to start, pre condition the battery if cold, climate to start, hop in and go.
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.
Unser Ioniq5 hat nach 4 Jahren und knapp 60.000€ immer noch einen SoH von 100%. Haben zwecks Weiterverkauf extra auslesen und dokumentieren lassen. Zudem gibt Hyundai 5 Jahre allgemeine Garantie und 8 Jahre Garantie auf den Akku. Wir waren sehr zufrieden mit dem Kauf und mögen den IONiQ immer noch sehr.
Mine on my previous car, a 2016 elantra lasted 8 years with huge winter temp drops up to -45 celcius
They battery they install is pretty good, other people around here need to change it after 5 years
If the battery dropped to 9V it is probably defective.
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.
Just bought a new G63, same issue!
My I6 battery died after 4mo and 2200km (1370mi). Car is sitting at the dealership awaiting warranty decision.
