Battery Bosch or OEM Mercedes

I have recently had both batteries replaced and the garage I use recommends Bosch as they have a 6 year ' no quibble ' (unlike VW) warranty . They are to the same spec as the Varta batteries and the right one is a 62ah normal lead acid type .

Dude save your money and chance battery yourself. I disconnected battery million times before and all i needed to do is "relearning window position". I bought Bosch group size 48 battery from Pepboys. It fits like glove and has 3 year warranty.

Alright so i picked up a bosch 750 cca battery and threw that in her on another -10 F day, cycled the glow plugs once and she fired up like it was a mid summer day. Hasnt given me any trouble since and its been nothing but cold here.

I'm using a Bosch Group 48 battery (it is 26 months old now) from Pep-boys. Their testing machine result says 'good battery' The guy at the store said, it was as good as a new one.

Bosch Battery from Pep Boys 80 Bucks with a 20 dollar rebate. OEM fit.

I've done all the scheduled maintenance on the car over the last 6 months including: Bosch S5 Battery

Walmart everstart battery lasted about a year from my experience. This used car i bought came with a Bosch battery. it died right before 3 year free replacement. I took it to the pepboys and they gave new one for free.

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've been seeing the same issue with batteries branded under Bosch and Champion. On several cars, I rarely had to replace batteries, now it seems like it is a 1-2 year thing on any battery. They are dying faster without ability to recharge. I just posted in the Scirocco forums that my 3 year warrantied Bosch battery is no longer holding a charge and its not even 11 months since I bought it. Glad to know that I'm not alone in seeing that engineered battery obsolescence seems to have arrived.
