Battery Duracell or OEM Mercedes

Duracell flooded lead acid would be a good choice and around $200.

I bought Duracell from Sams club. relatively easy coding with OBD11

the only time it failed me was when the battery died after 100k miles.

My 2015 Jeep Patriot's factory battery from Chrysler had one, until I replaced it last year with a Sam's Club Duracell special

I got a Duracell from batteries plus because it has a two year warranty. Starts strong so far, but it’s only been maybe 4 months.

CYL10014 Duracell Ultra 14AH-BS 12V 220CCA AGM Powersport Battery. First thing I switched when I brought the rogue home. Goodbye tender.

Just used Duracell. We will see how long they last.

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.

Duracell killed 6 pieces of electronics of mine over 10 years. If you paid me, I would not use them.

We refuse to buy Duracell. They leak and are awful. Never again.
