vs
Battery OEM KIA or OEM Mercedes
Reviews
Even though the battery tested fine the problem went when I replaced the battery.
Pros: problem went away
Vehicle:
Kia Ceed
Currently have a MB EQS that’s fantastic for about 1/3 of what it cost new.
Pros: fantastic, great value
Also, most car manufacturers know that customers are generally bad at doing the "correct" thing, so they protect their batteries by design.
When you are charging to 100% you are actually closer to 95-97%, when you run your car to 0% it's actually 5-7%
All because it's easier to show you another number and build the protection into the system, than to change people's habits.
Pros: batteries protected by design
Vehicle:
Kia
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
m.b. buy a Benz battery?
If the battery dropped to 9V it is probably defective.
Cons: battery probably defective
I bought a ‘24 GT with 5k miles and regret it every day. The battery had to be replaced at 9k miles and we had a loaner for a 5 weeks. Everyday issues like Carplay not working 50% of the time and the backup sensors being way too sensitive drive me insane.
Cons: battery replaced, carplay issues
Vehicle:
Kia
Mileage: 5000 km
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
I have a Kia Soul that goes through the OEM batteries every two-three years.
Cons: short lifespan, lasts 2-3 years
Vehicle:
Kia Soul
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
