Battery OPTIMA or Exide

I put an Optima Yellow Top battery into my 2018 OB 3.6R because the CCAs of the stock battery were pitiful (490 vs 720). Maybe check out other brands aside from Duralast? Also, get something that’s way beefier than the stock battery, especially if you live in hot or cold climates.

I don't see it as overkill. It might have unused capacity, but I'd also rather have a battery that stands up to more than just enough.

I don't think they are good at inverters, but I have used their battery for ups which lasted 4 years, now i am using the second one which completed one year

VW lists 3 batteries, 1 AGM (68 Ah, Varta) and 2 flooded (72 Ah, Varta and 59 Ah, Exide) that may be used.

I e been happy with them in my last 3 vehicles.

I had an Optima red top in my 89 4runner and that thing lasted for 12 fucking years. Needless to say I bought another one.

I run the red top. I haven't noticed any issues except it doesn't fit the stock tray.

Yes it's overkill if you don't need it. Standard batteries are perfectly fine for 99% of use cases

It literally is of 0 benefit and in fact they have shown to have a shorter lifetime in these applications.

Optimas quality fell off hard when they moved manufacturing to Mexico. They've been riding on their previous reputation ever since.
