vs
Battery Energizer or OEM Mercedes
Reviews
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.
Pros: long lasting, reliable
Vehicle:
Mercedes Sprinter
I put a Japan made energizer 2300mh storage at least for 8 monts, charged before storage and surprise, they make my flash work very quick even at maximum power, recycling flash time is even better than manufacturer specs.
Pros: quick flash, better specs
Cons: weak chinese made
I typically use what is shipped with the packaging. Most of my red dots are trijicon and they ship with energizer so I will continue to use it. I feel the companies do their own testing trail and error with battery life and usage at all power levels under all temperatures.
Pros: good battery life
Energizer. Better QC than Duracell imho.
Pros: better quality control
Duracell lasted 18 months on my RMR 3.25 Type 2 on auto setting, Energizer lasted 23 months on same setting!
Pros: Energizer lasts longer
Cons: Duracell shorter lifespan
Having ran both Duracell procell, and Energizer lithiums in RMR's, the energizers last 3+ years. I've gotten 2-2.5 years out of Duracell.
Pros: Energizer lasts longer
Cons: Duracell shorter lifespan
If the battery dropped to 9V it is probably defective.
Cons: battery 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.
Cons: battery drain problem, annoying, problem persists after new battery
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.
Cons: low battery alerts, critically low battery
Just bought a new G63, same issue!
Cons: same issue
