Battery OEM Nissan or OEM Mercedes

Put one in my Frontier last winter, and had more consistent starts. Cost half of Nissan dealership with higer CCA.

Saturday morning, we pull up to the house outside of Palmdale to this scene - a beat ass Chevy Celebrity trying to jump start an even more thrashed Nissan Stanza. The battery was fully charged, but it wouldn't start because it was still in 'drive.' After almost burning the thing down with improperly attached jumper cables, we were ready for a test drive. It ran... kinda. It was firing on 3...sometimes 4 cylinders, and the oil was overfilled by about 2 quarts.

I had the same problem. My car was brand new too but was sitting for a bit before it was sold to me. I brought it in to get charged a few times but the message was still coming up and I was definitely driving it enough. Eventually they just changed the battery under warranty.

The batteries Mercedes uses seem to be really poor quality. I have a daily class and it seems they are changing the battery every 1.5 years so far on average…

I've dealt with this issue on both of my newer AMG vehicles. My older ones never had this problem. From my understanding, this is caused by the new mbux system being a bit of a power hog. I eventually had to invest in a trickle charger, and I have to charge both of my AMGs 3-4 times per year. It gets worse as your battery gets toward the end of its lifespan.
