vs
Battery Energizer 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
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
Cons: lose battery at 80mph
m.b. buy a Benz battery?
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
Energizer is a shit battery. I had to put an Energizer one out of no options and that barely lasted a year.
Cons: barely lasted a year
This is the worst battery i tried, Enegizer lasted less than a year, maybe around 6 months only and it started dying.
Cons: died in 6 months
It's not only Energizer, its also whatever cheap brand I have. Might be a law, I think.
I do hate them, either cutting your fingers or have the cell fly out like a chemical saucer.
Pros: null
Cons: cutting fingers, cell fly
