Yuasa builds a damn fine battery. The one in my C14 is still hanging in there after 6 years.
Yuasa is the good stuff. It's all I'll use in my bikes.
My battery was the [factory one from 2007], changed it in 2023. Couldn't find a replacement Varta back then and had to choose fast, so I picked Yuasa (Japanese brand) and it's working good till now.
I bought a shorter mobility scooter battery with same chemistry as the original, YUASA REC36-12, however the polarity was reversed. I extended the negative pole and installed it without an issue and car came back to normal.
Currently have a MB EQS that’s fantastic for about 1/3 of what it cost new.
Nice hack. I have a Yuasa that will be 13 years old this year and still going.
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.
m.b. buy a Benz battery?
Unfortunately have to disagree about Yuasa, This 2018 battery is not the same as what you will get as a replacement from Yuasa today. I think they moved manufacturing from Taiwan and the quality has fell. My last two DRZ400 batteries were Yuasa and they didnt last 2 years. Even with tender on for the few months I didnt ride the bike.
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.
