Battery

Is there anything special about the main battery on a 2015 s550? Mine is getting old, and I’ll probably change it before it gets cold. Any reason not to use NTB or Walmart for the swap?

Walmart or any auto store can likely replace your battery. Being 10 years old and with winter ensuing, it's a wise preventative decision.

Nothing special about it. Easy DYI or go to a place you like. Might be a good time to replace the auxiliary battery too.

I only got 8 years out of my 1st battery (2015 S-600) and it hardly gets cold in Texas.

Still, 8 years for a battery is pretty decent.

As others mentioned. It is your typical battery, get a costco battery along with their warranty benefits for a peace of mind if you like.

Because these vehicles with their sensitive electronics are so finicky, I always go back with OEM batteries. My practice over the years is to replace batteries and tires every 5 years regardless of mileage. It’s been cheap insurance against the unexpected for the 70 years I’ve been driving. 🔋

Hard to argue with verifiable results.
