Battery Duracell or OEM Mercedes

I had the same issue on my w213 - same warning every now and then until one day it just didn’t start. Replaced the battery and solved the issue.

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

I still prefer Duracell.

I've had good results from East Penn Duracell at Sam's Club. I just replaced one nearly 8 years old.

The best way to check is to go with a multimeter and get the highest voltage/closest manufactured date. Duracell might just be EverStart rebranded BUT NO the Walmart battery will last around 1-2 years, maybe less. If you want to make sure your covered with a good battery, that’s when you go to Advance Auto or AutoZone and get the battery with 3 years of warranty and swap it out right before the 3rd year ends and I find the batteries last me forever.

How's the Duracell Vs the oem? I have 6 battery to buy (2 per pack) for a similar ups (1300va from apc with same lcd).

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.

Power Sonic or Yuasa. Duracell is great for lots of service every year after an inspection. Never seen them make it to the next inspection alive.

My company uses Duracells. Do not recommend

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.
