Battery OPTIMA or OEM Mercedes

I did and what a misnomer 'dry cell' is. Yes they are great and expensive. Both standard and 'drycell' have liquid eletrolyte so it's weird to start talking about 'drycell'

My old car had an Optima Red Top in it for 10 years and never had a battery issue- but again, sitting on a tender most of the time.

Personally, I have a fondness for Optima batteries, particularly the Yellow Top, in any vehicle where there are a lot of accessories to run, though I have a Red Top in my daily driver.

I don't know, but I just bought an Optima Red Top battery with a three year waranty sold at a store that has a store in every city.

I use optima. Highly recommend it too

Hrp: Optima. Best batteries out there. Have only had 2 since 2001! Red top, yellow and blue. Red should be sufficient unless you've got mega stereo. 800 watts.

The red top really isn't that special and optima's tech in general is more beneficial in regard to durability than current delivery.

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.

I went through two of them in a season in my trail Jeep. I think years ago they were great batteries and the quality was there but now it’s just a brand name but junk product.
