Battery OEM Honda or OEM Mercedes
Best upgrade I did for my fit was upgrading to a 51r battery. Just the other day I left my interior lights on all night and I didn't notice until I went to work in the morning, but it started up no problem.
Historically, OEM Mercedes batteries are really good and last many years.
Cells in the battery are probably done. Happened to my wife\u2019s accord. Said the battery was fine and wouldn\u2019t charge because she barely drives it since she works from home and recommended we get a battery tender. Come to find out the charge of the battery was fine but the cells were dead which is why it wouldn\u2019t charge. Time for a new battery.
I\u2019ve jumpstarted my 2019 freightliner from a Honda Accord before.
I have gone through two batteries already. They seem to only last 3-4 years on this car - at least in my experience.
And the super small battery…
3 yrs on a Honda battery had me smh honestly.
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!
