Battery OEM Subaru or OEM Mercedes

When you say, \u201ctwo new batteries\u201d are you speaking of the big ones? There is a small one that operate your convenience/comfort items. It looks like a small garage door battery.

So we bought a new 550CCA battery and installed it and it started right up. When I pulled the 18 month old OEM battery out, I was shocked at the CCA rating: 356. 356!!!! That's insane.

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.

My battery keeps dying if I dont use my car for 1-2 days and Subaru is failing to address the issues.

Subaru has had a problem with their electrical systems since 2014. Batteries last 2 years, max. 2018 legacy is on its third battery in 4 years. 13,000 miles. $600.00 in batteries.

Subaru batteries aren't great in the cold either

My battery made for Subaru died on my 2017 Forester 2 weeks before the warranty ran out. SUBARU has their own problems with their batteries.

Subaru batteries suck
