vs
Battery OEM BMW or OEM Mercedes
Reviews
Currently have a MB EQS that’s fantastic for about 1/3 of what it cost new.
Pros: fantastic, great value
I have a 2020 GLB250 and mine was saying "12V battery" on and off for a few weeks. I checked under the hood with a multimeter and my main battery did have a low voltage while the car was off. I replaced it a few weeks back. No more notification.
Pros: no more notification
Cons: low voltage, on and off
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.
Pros: solved the issue
Cons: warning every now and then
Historically, OEM Mercedes batteries are really good and last many years.
Pros: good, last many years
But during the ownership i found it really reliable, the only things i needed fixing were: battery (it was the original one over 7 years old), tyres and brake discs/pads (consumables on any car) and the regular oil/filter services.
Pros: really reliable
Vehicle:
BMW X1
m.b. buy a Benz battery?
If the battery dropped to 9V it is probably defective.
Cons: battery probably defective
In the 166 body MB ML/GL, its under the passenger seat, with barely enough room to reach the rear terminal. It's also so far forward that you can barely grab the fuckin thing. Oh, did I mention that it is a group 49 battery.
Cons: hard to reach
My new BMW X3 was reliable.
It reliably would NOT start whenever the temperature dropped below -20C, even with a battery tender on it. The dealer couldn’t find anything wrong with it.
Cons: would not start
Vehicle:
BMW X3
The battery lasted about two years. I had a company car at the time and only drove the BMW on my days off, and didn't drive long or far. The short, infrequent drives basically never allowed the battery to completely charge, resulting in it's early death.
Cons: early death, lasted two years
Vehicle:
BMW
