vs
Battery Duralast 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
You need this one, and it takes about 10 minutes to install. Just hop into the front trunk, unbolt the bar from the firewall that braces the battery -- iirc 13mm. Remove the tire inflator and the box (pulls right out), remove the other bolt, unscrew the two terminals (10mm probably), swap batteries. Done.
Pros: easy to install, 10 minutes
Vehicle:
Porsche Cayman
Historically, OEM Mercedes batteries are really good and last many years.
Pros: good, last many years
Just had a 5yo Napa battery die, put a new Duralast Platinum Elite in there, back to running normal except 2 things: 1/ Random engine fan activation seems to be what killed the previous battery. Still happening.
Pros: back to running normal
Cons: random fan activation, battery died
Vehicle:
Volkswagen Golf
m.b. buy a Benz battery?
Duralast is almost always johnson controls, made in mexico.
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
Last December, the OEM battery died and I replaced it with a new Duralast battery from AutoZone. Fast forward to today, the car wouldn\u2019t start at all. Had to jump it just to get it running and drove straight to AutoZone to get it tested.\n\nBattery tested good. Starter tested good.\nBut the alternator failed, specifically the charging current test.
Cons: alternator failed charging test
Vehicle:
Mazda
Mileage: 31000 km
